php中运用http调用的GET和POST方法示例

使用到的函数是curl_init, curl_setopt, curl_exec,curl_close。

默认是GET方法，可以选择是否使用Header：

$ch = curl_init();curl_setopt($ch, CURLOPT_URL, "$url");curl_setopt($ch, CURLOPT_TIMEOUT, 2);curl_setopt($ch, CURLOPT_HEADER, 1); //如果设为0，则不使用headercurl_setopt($ch,CURLOPT_RETURNTRANSFER,1);$result = curl_exec($ch);curl_close($ch);

POST方法：

$ch = curl_init();curl_setopt($ch,CURLOPT_URL,'＄url');curl_setopt($ch,CURLOPT_POST,1);curl_setopt($ch,CURLOPT_RETURNTRANSFER,TRUE);$vars =sprintf('from=%d&to=%d&subject=%s&body=%s',$from, $to, urlencode($subject), urlencode($body));curl_setopt($ch,CURLOPT_POSTFIELDS,$vars);$ret = curl_exec($ch);curl_close($ch);
