<?php
$file_path = "test.txt";
if (file_exists($file_path))
{
$fp=fopen($file_path, "a+");
$con=fread($fp, filesize($file_path));
echo $con;
}else
{
echo "文件不存在";
}
fclose($fp);
?>
上面的写法为啥当文件test.txt是0字节的时候提示这个呢
Warning: fread() [function.fread]: Length parameter must be greater than 0 in D:\APMServ5.2.6\www\htdocs\01\file.php on line 7
另外上面和下面这两种读取方式哪个更好点
<?php
$file_path = "test.txt";
$con=file_get_contents($file_path);
$con=str_replace("\r\n","<br/>",$con);
echo $con;
?>
------解决思路----------------------
下面的要好点,上面的fread有各种限制
