在php中file_get_contents函数可直接采集远程服务器内容,然后保存到一个变量中了,介理一般都会把file_get_contents、fsockopen等一些IO操作的函数禁用掉,因为它们怕被 DDOS
那么一般情况下,我们改不了服务器的 inc.php,只能自己写一套IO来代替上面的PHP函数了。

我们可以用下面的代码代替

//禁用file_get_contents的解决办法 |
curl是一个利用URL语法规定来传输文件和数据的工具,支持很多协议,如HTTP、FTP、TELNET等,它不会被服务器禁用,所以我们可以用来模拟file_get_contents一样打开一条URL。
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
代码如下 | 复制代码 |
function 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; } ?> |
