curl实现put请求

<?php

function curlrequest($url,$data,$method='post'){
    $ch = curl_init(); //初始化CURL句柄
    curl_setopt($ch, CURLOPT_URL, $url); //设置请求的URL
    curl_setopt($ch, CURLOPT_RETURNTRANSFER,1); //设为TRUE把curl_exec()结果转化为字串，而不是直接输出
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, $method); //设置请求方式

    curl_setopt($ch,CURLOPT_HTTPHEADER,array("X-HTTP-Method-Override: $method"));//设置HTTP头信息
    curl_setopt($ch, CURLOPT_POSTFIELDS, $data);//设置提交的字符串
    $document = curl_exec($ch);//执行预定义的CURL
    if(!curl_errno($ch)){
      $info = curl_getinfo($ch);
      echo 'Took ' . $info['total_time'] . ' seconds to send a request to ' . $info['url'];
    } else {
      echo 'Curl error: ' . curl_error($ch);
    }
    curl_close($ch);

    return $document;
}

$url = 'http://localhost/test/curl.php';
$data = "request from put method";
$return = curlrequest($url, $data, 'put');

var_dump($return);exit;
?>

<?php
$arguments = file_get_contents('php://input');
print_r($arguments);
