file_get_contents函数
$file_contents = file_get_contents('http://www.5imoban.net/'); 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
$ch = curl_init(); $timeout = 5; curl_setopt ($ch, CURLOPT_URL, 'http://www.5imoban.net'); curl_setopt ($ch, CURLOPT_RETURNTRANSFER, 1); curl_setopt ($ch, CURLOPT_CONNECTTIMEOUT, $timeout); $file_contents = curl_exec($ch); curl_close($ch); echo $file_contents;利用function_exists函数来判断php是否支持一个函数可以轻松写出下面函数
function vita_get_url_content($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; }
