< ?php

$file_contents = file_get_contents('http://www.ccvita.com/');echo $file_contents;?>

有些主机服务商把php的allow_url_fopen选项是关闭了，就是没法直接使用file_get_contents来获取远程web页面的内容。那就是可以使用另外一个函数curl。

　

< ?php$ch = curl_init();$timeout = 5; curl_setopt ($ch, CURLOPT_URL, 'http://www.ccvita.com');curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);$file_contents = curl_exec($ch);curl_close($ch);echo $file_contents;?>

利用function_exists函数来判断php是否支持一个函数可以轻松写出下面函数< ?phpfunction vita_get_url_content($url) {if(function_exists('file_get_contents')) {$file_contents = file_get_contents($url);} else {$ch = curl_init();$timeout = 5; curl_setopt ($ch, CURLOPT_URL, $url);curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);$file_contents = curl_exec($ch);curl_close($ch);}return $file_contents;}?>
