php調用遠路url的四種方法

php調用遠程url的四種方法
1、 用file_get_contents 以get方式擷取內容
樣本：

$html = file_get_contents($url); 

2、 用fopen開啟url, 以get方式擷取內容
樣本：

$fp = fopen($url, 'r'); $html = stream_get_meta_data($fp); 

3、用 file_get_contents函數,以post方式擷取url

 $data = array ('test' => 'hellword'); $data = http_build_query($data); $opts = array (  'http' => array (  'method' => 'POST',  'header'=> "Content-type: application/x-www-form-urlencoded\r\n" .     "Content-Length: " . strlen($data) . "\r\n",  'content' => $data  ), ); $context = stream_context_create($opts); $html = file_get_contents($url, false, $context);

4、使用curl庫，使用 curl庫之前，需先確認有開啟curl擴充

$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); echo $file_contents;
