在ubuntu中php环境的配置相对容易，可参看http://www.cnblogs.com/aqhistory/archive/2011/04/10/2011713.html
主要命令sudo apt-get install apache2 mysql-server mysql-client php5 php5-gd php5-mysql
sudo apt-get install phpmyadmin
window下PHP环境的配置，相对复杂一些，我2个星期才搞定，惭愧。现在此记录安装过程。
1、实现安装了mysql5.5完整版，进行了配置，并能正常使用（配置环境变量path）
2、安装了apache2.2，配置文件 ../conf/httpd.conf 。默认端口Listen 80，可以不改动（但要记得与IIS服务器会发生端口占用冲突），也可以改成其他（非80时浏览器访问要加上端口。出现如下界面，表示apache单独的配置成功。
3、官网下载php5-2-17，解压某位置（文件夹可以重命名）
php5的配置文件是php.ini
为了顺利地加载模块，需要将php的主目录和php下ext子目录，加入到环境变量|系统变量Path中
下面是配置的重点，关联php和apache，php关联mysql
4、修改apache配置文件httpd.conf
下面是我目前系统的apache配置完整文档，主要修改增加的几处用红色标记。
## This is the main Apache HTTP server configuration file. It contains the# configuration directives that give the server its instructions.# See <URL:http://httpd.apache.org/docs/2.2> for detailed information.# In particular, see # <URL:http://httpd.apache.org/docs/2.2/mod/directives.html># for a discussion of each configuration directive.## Do NOT simply read the instructions in here without understanding# what they do. They're here only as hints or reminders. If you are unsure# consult the online docs. You have been warned. ## Configuration and logfile names: If the filenames you specify for many# of the server's control files begin with "/" (or "drive:/" for Win32), the# server will use that explicit path. If the filenames do *not* begin# with "/", the value of ServerRoot is prepended -- so "logs/foo.log"# with ServerRoot set to "D:/Program Files/Apache Software Foundation/Apache2.2" will be interpreted by the# server as "D:/Program Files/Apache Software Foundation/Apache2.2/logs/foo.log".## NOTE: Where filenames are specified, you must use forward slashes# instead of backslashes (e.g., "c:/apache" instead of "c:\apache").# If a drive letter is omitted, the drive on which httpd.exe is located# will be used by default. It is recommended that you always supply# an explicit drive letter in absolute paths to avoid confusion.## ServerRoot: The top of the directory tree under which the server's# configuration, error, and log files are kept.## Do not add a slash at the end of the directory path. If you point# ServerRoot at a non-local disk, be sure to point the LockFile directive# at a local disk. If you wish to share the same ServerRoot for multiple# httpd daemons, you will need to change at least LockFile and PidFile.#ServerRoot "D:/Program Files/Apache Software Foundation/Apache2.2"## Listen: Allows you to bind Apache to specific IP addresses and/or# ports, instead of the default. See also the <VirtualHost># directive.## Change this to Listen on specific IP addresses as shown below to # prevent Apache from glomming onto all bound IP addresses.##Listen 12.34.56.78:80Listen 80## Dynamic Shared Object (DSO) Support## To be able to use the functionality of a module which was built as a DSO you# have to place corresponding `LoadModule' lines at this location so the# directives contained in it are actually available _before_ they are used.# Statically compiled modules (those listed by `httpd -l') do not need# to be loaded here.## Example:# LoadModule foo_module modules/mod_foo.so#LoadModule actions_module modules/mod_actions.soLoadModule alias_module modules/mod_alias.soLoadModule asis_module modules/mod_asis.soLoadModule auth_basic_module modules/mod_auth_basic.so#LoadModule auth_digest_module modules/mod_auth_digest.so#LoadModule authn_alias_module modules/mod_authn_alias.so#LoadModule authn_anon_module modules/mod_authn_anon.so#LoadModule authn_dbd_module modules/mod_authn_dbd.so#LoadModule authn_dbm_module modules/mod_authn_dbm.soLoadModule authn_default_module modules/mod_authn_default.soLoadModule authn_file_module modules/mod_authn_file.so#LoadModule authnz_ldap_module modules/mod_authnz_ldap.so#LoadModule authz_dbm_module modules/mod_authz_dbm.soLoadModule authz_default_module modules/mod_authz_default.soLoadModule authz_groupfile_module modules/mod_authz_groupfile.soLoadModule authz_host_module modules/mod_authz_host.so#LoadModule authz_owner_module modules/mod_authz_owner.soLoadModule authz_user_module modules/mod_authz_user.soLoadModule autoindex_module modules/mod_autoindex.so#LoadModule cache_module modules/mod_cache.so#LoadModule cern_meta_module modules/mod_cern_meta.soLoadModule cgi_module modules/mod_cgi.so#LoadModule charset_lite_module modules/mod_charset_lite.so#LoadModule dav_module modules/mod_dav.so#LoadModule dav_fs_module modules/mod_dav_fs.so#LoadModule dav_lock_module modules/mod_dav_lock.so#LoadModule dbd_module modules/mod_dbd.so#LoadModule deflate_module modules/mod_deflate.soLoadModule dir_module modules/mod_dir.so#LoadModule disk_cache_module modules/mod_disk_cache.so#LoadModule dumpio_module modules/mod_dumpio.soLoadModule env_module modules/mod_env.so#LoadModule expires_module modules/mod_expires.so#LoadModule ext_filter_module modules/mod_ext_filter.so#LoadModule file_cache_module modules/mod_file_cache.so#LoadModule filter_module modules/mod_filter.so#LoadModule headers_module modules/mod_headers.so#LoadModule ident_module modules/mod_ident.so#LoadModule imagemap_module modules/mod_imagemap.soLoadModule include_module modules/mod_include.so#LoadModule info_module modules/mod_info.soLoadModule isapi_module modules/mod_isapi.so#LoadModule ldap_module modules/mod_ldap.so#LoadModule logio_module modules/mod_logio.soLoadModule log_config_module modules/mod_log_config.so#LoadModule log_forensic_module modules/mod_log_forensic.so#LoadModule mem_cache_module modules/mod_mem_cache.soLoadModule mime_module modules/mod_mime.so#LoadModule mime_magic_module modules/mod_mime_magic.soLoadModule negotiation_module modules/mod_negotiation.so#LoadModule proxy_module modules/mod_proxy.so#LoadModule proxy_ajp_module modules/mod_proxy_ajp.so#LoadModule proxy_balancer_module modules/mod_proxy_balancer.so#LoadModule proxy_connect_module modules/mod_proxy_connect.so#LoadModule proxy_ftp_module modules/mod_proxy_ftp.so#LoadModule proxy_http_module modules/mod_proxy_http.so#LoadModule proxy_scgi_module modules/mod_proxy_scgi.so#LoadModule reqtimeout_module modules/mod_reqtimeout.so#LoadModule rewrite_module modules/mod_rewrite.soLoadModule setenvif_module modules/mod_setenvif.so#LoadModule speling_module modules/mod_speling.so#LoadModule ssl_module modules/mod_ssl.so#LoadModule status_module modules/mod_status.so#LoadModule substitute_module modules/mod_substitute.so#LoadModule unique_id_module modules/mod_unique_id.so#LoadModule userdir_module modules/mod_userdir.so#LoadModule usertrack_module modules/mod_usertrack.so#LoadModule version_module modules/mod_version.so#LoadModule vhost_alias_module modules/mod_vhost_alias.soLoadModule php5_module "d:/Program Files/php-5.2.17-Win32-VC6-x86/php5apache2_2.dll" PHPIniDir "d:/Program Files/php-5.2.17-Win32-VC6-x86"<IfModule !mpm_netware_module><IfModule !mpm_winnt_module>## If you wish httpd to run as a different user or group, you must run# httpd as root initially and it will switch. ## User/Group: The name (or #number) of the user/group to run httpd as.# It is usually good practice to create a dedicated user and group for# running httpd, as with most system services.#User daemonGroup daemon</IfModule></IfModule># 'Main' server configuration## The directives in this section set up the values used by the 'main'# server, which responds to any requests that aren't handled by a# <VirtualHost> definition.

5、php的配置
我目前系统php配置文件php.ini完整内容如下，主要增、改的地方用红色标记
[PHP];;;;;;;;;;;; WARNING ;;;;;;;;;;;;; This is the default settings file for new PHP installations.; By default, PHP installs itself with a configuration suitable for; development purposes, and *NOT* for production purposes.; For several security-oriented considerations that should be taken; before going online with your site, please consult php.ini-recommended; and http://php.net/manual/en/security.php.;;;;;;;;;;;;;;;;;;;; About php.ini ;;;;;;;;;;;;;;;;;;;;; This file controls many aspects of PHP's behavior. In order for PHP to; read it, it must be named 'php.ini'. PHP looks for it in the current; working directory, in the path designated by the environment variable; PHPRC, and in the path that was defined in compile time (in that order).; Under Windows, the compile-time path is the Windows directory. The; path in which the php.ini file is looked for can be overridden using; the -c argument in command line mode.;; The syntax of the file is extremely simple. Whitespace and Lines; beginning with a semicolon are silently ignored (as you probably guessed).; Section headers (e.g. [Foo]) are also silently ignored, even though; they might mean something in the future.;; Directives are specified using the following syntax:; directive = value; Directive names are *case sensitive* - foo=bar is different from FOO=bar.;; The value can be a string, a number, a PHP constant (e.g. E_ALL or M_PI), one; of the INI constants (On, Off, True, False, Yes, No and None) or an expression; (e.g. E_ALL & ~E_NOTICE), or a quoted string ("foo").;; Expressions in the INI file are limited to bitwise operators and parentheses:; | bitwise OR; & bitwise AND; ~ bitwise NOT; ! boolean NOT;; Boolean flags can be turned on using the values 1, On, True or Yes.; They can be turned off using the values 0, Off, False or No.;; An empty string can be denoted by simply not writing anything after the equal; sign, or by using the None keyword:;; foo = ; sets foo to an empty string; foo = none ; sets foo to an empty string; foo = "none" ; sets foo to the string 'none';; If you use constants in your value, and these constants belong to a; dynamically loaded extension (either a PHP extension or a Zend extension),; you may only use these constants *after* the line that loads the extension.;;;;;;;;;;;;;;;;;;;;;; About this file ;;;;;;;;;;;;;;;;;;;;; All the values in the php.ini-dist file correspond to the builtin; defaults (that is, if no php.ini is used, or if you delete these lines,; the builtin defaults will be identical).;;;;;;;;;;;;;;;;;;;;; Language Options ;;;;;;;;;;;;;;;;;;;;;; Enable the PHP scripting language engine under Apache.engine = On; Enable compatibility mode with Zend Engine 1 (PHP 4.x)zend.ze1_compatibility_mode = Off; Allow the <? tag. Otherwise, only <?php and <script> tags are recognized.; NOTE: Using short tags should be avoided when developing applications or; libraries that are meant for redistribution, or deployment on PHP; servers which are not under your control, because short tags may not; be supported on the target server. For portable, redistributable code,; be sure not to use short tags.short_open_tag = On; Allow ASP-style <% %> tags.asp_tags = Off; The number of significant digits displayed in floating point numbers.precision = 12; Enforce year 2000 compliance (will cause problems with non-compliant browsers)y2k_compliance = On; Output buffering allows you to send header lines (including cookies) even; after you send body content, at the price of slowing PHP's output layer a; bit. You can enable output buffering during runtime by calling the output; buffering functions. You can also enable output buffering for all files by; setting this directive to On. If you wish to limit the size of the buffer; to a certain size - you can use a maximum number of bytes instead of 'On', as; a value for this directive (e.g., output_buffering=4096).output_buffering = Off; You can redirect all of the output of your scripts to a function. For; example, if you set output_handler to "mb_output_handler", character; encoding will be transparently converted to the specified encoding.; Setting any output handler automatically turns on output buffering.; Note: People who wrote portable scripts should not depend on this ini; directive. Instead, explicitly set the output handler using ob_start().; Using this ini directive may cause problems unless you know what script; is doing.; Note: You cannot use both "mb_output_handler" with "ob_iconv_handler"; and you cannot use both "ob_gzhandler" and "zlib.output_compression".; Note: output_handler must be empty if this is set 'On' !!!!; Instead you must use zlib.output_handler.;output_handler =; Transparent output compression using the zlib library; Valid values for this option are 'off', 'on', or a specific buffer size; to be used for compression (default is 4KB); Note: Resulting chunk size may vary due to nature of compression. PHP; outputs chunks that are few hundreds bytes each as a result of; compression. If you prefer a larger chunk size for better; performance, enable output_buffering in addition.; Note: You need to use zlib.output_handler instead of the standard; output_handler, or otherwise the output will be corrupted.zlib.output_compression = Off;zlib.output_compression_level = -1; You cannot specify additional output handlers if zlib.output_compression; is activated here.

This method is deprecated and is likely to be; unsupported in future versions of PHP/Zend. The encouraged method of; specifying which arguments should be passed by reference is in the function; declaration. You're encouraged to try and turn this option Off and make; sure your scripts work properly with it in order to ensure they will work; with future versions of the language (you will receive a warning each time; you use this feature, and the argument will be passed by value instead of by; reference).allow_call_time_pass_reference = On;; Safe Mode;safe_mode = Off; By default, Safe Mode does a UID compare check when; opening files.

ps: 我在安装的时候参考了很多网上文章，有些细节配置不太相同，不知道怎么回事，我在php5中加载了（去掉了下面2句前的；注释）
;extension=php_pdo_mssql.dll;extension=php_pdo_mysql.dll这2个模块，启动apache时，报错，从apache的错误日志../apache主目录/logs/error.txt看
在dos窗口中直接输入php也弹出提示
注释掉这2句，apache能正常启动，不再报错。dos环境中的php命令也正常了。
5、建立php项目，开始php之旅
可以直接在apache应用目录下，建立php项目。适合小型项目。
也可以用php IDE，zend studio , eclipse php studio ,eclipse中php插件，NetBeans IDE
本人起初安装了eclipse php studio，zend studio没有配置成功。在保证以上4不完成后，安装NetBeans后几乎不用什么额外配置。
用NetBeans开发的第一个php程序如下。
新建php项目（如果netbean没有配php5插件，需要手动下载），点击“下一步”，NetBeans IDE会自动找到系统的apache web和php.
再点击“下一步”，显示项目url访问地址，项目源文件会自动放置到apache应用目录htdocs中。点击“完成”
建立简单的php文件，主要代码是 phpinfo().
现在就可以点击，运行了。点击菜单栏的绿色运行按钮，就自动在浏览器中访问该新建的项目。
