深入file_get_contents函数抓取内容失败的原因分析_PHP
用file_get_contents来抓取页面内容不成功，可能是因为有些主机服务商把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。
下面是file_get_contents和curl两个函数同样功能的不同写法
file_get_contents函数的使用示例:
复制代码 代码如下:
$file_contents = file_get_contents(‘http://www.bitsCN.com');
echo $file_contents;
?>
换成curl函数的使用示例:
复制代码 代码如下:
$ch = curl_init();
$timeout = 5;
curl_setopt ($ch, CURLOPT_URL, ‘http://www.bitsCN.com');
curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1);
curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout);
$file_contents = curl_exec($ch);
curl_close($ch);
echo $file_contents;
?>
