前面已经分享了PHP常用功能代码片段(1~5)和PHP常用功能代码片段(6~10)，今天是第三篇，也就是第11到15这5个实现代码片段，希望可以帮到jquery学堂群里面的成员和广大对PHP开发的网友们提高开发效率，以下是第三篇文章。
11、PHP实现如何获取网址的PR值
/**功能:对URL进行编码*参数说明:$web_url 网站URL，不包含"http://"*/function HashURL($url){ $SEED = "Mining PageRank is AGAINST GOOGLE’S TERMS OF SERVICE. Yes, I’m talking to you, scammer."; $Result = 0x01020345; for ($i=0; $i<strlen($url); $i++) { $Result ^= ord($SEED{$i%87}) ^ ord($url{$i}); $Result = (($Result >> 23) & 0x1FF) | $Result << 9; } return sprintf("8%x", $Result);}/**功能:根据google提供的pr查询接口获取pagerank*参数说明:$domain 网站域名，不包含"http://"*/function pagerank($domain){ $StartURL = "http://toolbarqueries.google.com/tbr?client=navclient-auto&features=Rank:&q=info:"; $GoogleURL = $StartURL.$domain. '&ch='.HashURL($domain); echo $GoogleURL.'<br>'; $fcontents = file_get_contents("$GoogleURL"); $pagerank = substr($fcontents,9); if (!$pagerank) return "0";else return $pagerank;}//调用方法echo pagerank("www.jq-school.com");
12、PHP实现为post过来的数据转换编码
$info = array();foreach($_POST as $key => $value){ $info[$key] = iconv("utf-8","gb2312",$value);}
13、PHP实现获取客户端IP地址及所在地区
function address($ip) { $info = json_decode(file_get_contents('http://int.dpool.sina.com.cn/iplookup/iplookup.php?ip='.$ip.'&format=json'), false); if ($info ->ret == 1) { if ($info ->province != $info ->city) { return $info ->country.",".$info ->province."(".$info ->city.") ".$info ->district." ".$info ->desc; } else { return $info ->country.",".$info ->province." ".$info ->district." ".$info ->desc; } } else { return '地球'; }}
14、PHP实现取得客户端浏览器版本
function browser($ua) { if (stripos($ua, "Googlebot")) { $browser = "谷歌蜘蛛"; } elseif(stripos($ua, "Baiduspider") !== false) { $browser = "百度蜘蛛"; } elseif(stripos($ua, "Yahoo!") !== false) { $browser = "雅虎蜘蛛"; } elseif(stripos($ua, "bingbot")) { $browser = "必应蜘蛛"; } elseif(stripos($ua, "YRSpider")) { $browser = "云壤蜘蛛"; } elseif(stripos($ua, "Yeti") !== false) { $browser = "Naver蜘蛛"; } elseif(stripos($ua, "Maxthon")) { if (stripos($ua, "AppleWebKit")) { $browser = "遨游浏览器(极速模式)"; } elseif(stripos($ua, "Trident")) { $browser = "遨游浏览器(兼容模式)"; } elseif(stripos($ua, "MAXTHON 2.0")) { $browser = "遨游浏览器2.0"; } } elseif(stripos($ua, "Firefox")) { $browser = "火狐浏览器"; } elseif(stripos($ua, "Opera") == 0 && stripos($ua, "Presto")) { $browser = "Opera"; } elseif(stripos($ua, "BIDUBrowser")) { if (stripos($ua, "Trident")) { $browser = "百度浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebKit")) { $browser = "百度浏览器(极速模式)"; } } elseif(stripos($ua, "Ruibin")) { $browser = "瑞影浏览器"; } elseif(stripos($ua, "qihu theworld")) { if (stripos($ua, "Trident")) { $browser = "世界之窗浏览器"; } elseif(stripos($ua, "AppleWebKit")) { $browser = "世界之窗浏览器(极速模式)"; } } elseif(stripos($ua, "MetaSr")) { if (stripos($ua, "Trident")) { $browser = "搜狗高速浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebKit")) { $browser = "搜狗高速浏览器(极速模式)"; } } elseif(stripos($ua, "LBBROWSER")) { if (stripos($ua, "Trident")) { $browser = "猎豹浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebKit")) { $browser = "猎豹浏览器(极速模式)"; } } elseif(stripos($ua, "YLMFBR")) { $browser = "115浏览器"; } elseif(stripos($ua, "QQBrowser")) { if (stripos($ua, "Trident")) { $browser = "QQ浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebKit")) { $browser = "QQ浏览器(极速模式)"; } } elseif(stripos($ua, "TencentTraveler")) { $browser = "腾讯TT浏览器"; } elseif(stripos($ua, "TaoBrowser")) { if (stripos($ua, "Trident")) { $browser = "淘宝浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebkit")) { $browser = "淘宝浏览器(极速模式)"; } } elseif(stripos($ua, "CoolNovo")) { $browser = "枫树浏览器"; } elseif(stripos($ua, "SaaYaa")) { $browser = "闪游浏览器"; } elseif(stripos($ua, "360SE")) { $browser = "360安全浏览器"; } elseif(stripos($ua, "360EE")) { if (stripos($ua, "Trident")) { $browser = "360极速浏览器(兼容模式)"; } elseif(stripos($ua, "AppleWebkit")) { $browser = "360极速浏览器(极速模式)"; } } elseif(stripos($ua, "Konqueror")) { $browser = "Konqueror"; } elseif(stripos($ua, "Chrome")) { $browser = "谷歌浏览器"; } elseif(stripos($ua, "Safari")) { $browser = "Safari"; } elseif(stripos($ua, "MSIE")) { $ver = explode(";", substr($ua, stripos($ua, "MSIE") + 5, 4)); $ver = $ver[0]; $browser = "IE ".$ver; } elseif(stripos($ua, "UCWEB")) { $browser = "UCWEB浏览器"; } elseif(stripos($ua, "WAP")) { $browser = "Mobile浏览器"; } else { $browser = $ua; } if ($browser == '') $browser = $ua; return $browser;}
15、PHP实现取得客户端操作系统版本
function os($ua) { $os = ""; if (stripos($ua, "Googlebot")) { $os = "谷歌蜘蛛"; } elseif(stripos($ua, "Baiduspider") !== false) { $os = "百度蜘蛛"; } elseif(stripos($ua, "Yahoo!") !== false) { $os = "雅虎蜘蛛"; } elseif(stripos($ua, "bingbot")) { $os = "必应蜘蛛"; } elseif(stripos($ua, "YRSpider")) { $os = "云壤蜘蛛"; } elseif(stripos($ua, "Yeti") !== false) { $os = "Naver蜘蛛"; } elseif(stripos($ua, "Windows NT")) { switch (substr($ua, stripos($ua, "Windows NT") + 11, 3)) { case 5.0: { $os = "Windows 2000"; break; } case 5.1: { $os = "Windows XP"; break; } case 5.2: { $os = "Windows 2003"; break; } case 6.0: { $os = "Windows Vista/2008"; break; } case 6.1: { $os = "Windows 7"; break; } case 6.2: { $os = "Windows 8"; break; } default: { $os = "Windows"; break; } } if (stripos($ua, "WOW64")) { $os.= "(X64)"; } else { $os.= "(X86)"; } } elseif(stripos($ua, "Android")) { $os = substr($ua, stripos($ua, "Android"), 11); } elseif(stripos($ua, "Linux")) { if (stripos($ua, "i686")) { $os = "Linux X86"; } else { $os = "Linux"; } if (stripos($ua, "X11")) { $os.= "(X Window)"; } } elseif(stripos($ua, "Macintosh")) { $os = "Mac"; } elseif(stripos($ua, "IOS")) { $os = "iOS"; } elseif(stripos($ua, "ZTE")) { $os = "ZTE"; } elseif(stripos($ua, "Windows 98")) { $os = "Windows 98"; } else { $os = "未知系统"; } return $os;}?
