这里有这样的代码:

<?php
$postdata = http_build_query(
    array(
        'name' => 'Robert',
        'id' => '1'
    )
);
$opts = array('http' =>
    array(
        'method' => 'POST',
        'header' => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);
$context = stream_context_create($opts);
$result = file_get_contents('http://localhost:8000/api/test', false, $context);
echo $result;?>

尝试PEAR的HTTP_Request2包来轻松地发送POST请求。或者，您可以使用PHP的curl函数或使用PHP流上下文。

HTTP_Request2还使模拟服务器成为可能，因此您可以轻松地对代码进行单元测试

这里有这样的代码:

<?php
$postdata = http_build_query(
    array(
        'name' => 'Robert',
        'id' => '1'
    )
);
$opts = array('http' =>
    array(
        'method' => 'POST',
        'header' => 'Content-type: application/x-www-form-urlencoded',
        'content' => $postdata
    )
);
$context = stream_context_create($opts);
$result = file_get_contents('http://localhost:8000/api/test', false, $context);
echo $result;?>

你可以使用cURL:

<?php
//The url you wish to send the POST request to
$url = $file_name;

//The data you want to send via POST
$fields = [
    '__VIEWSTATE '      => $state,
    '__EVENTVALIDATION' => $valid,
    'btnSubmit'         => 'Submit'
];

//url-ify the data for the POST
$fields_string = http_build_query($fields);

//open connection
$ch = curl_init();

//set the url, number of POST vars, POST data
curl_setopt($ch,CURLOPT_URL, $url);
curl_setopt($ch,CURLOPT_POST, true);
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

//So that curl_exec returns the contents of the cURL; rather than echoing it
curl_setopt($ch,CURLOPT_RETURNTRANSFER, true); 

//execute post
$result = curl_exec($ch);
echo $result;
?>

PHP5的无卷曲方法:

$url = 'http://server.com/path';
$data = array('key1' => 'value1', 'key2' => 'value2');

// use key 'http' even if you send the request to https://...
$options = array(
    'http' => array(
        'header'  => "Content-type: application/x-www-form-urlencoded\r\n",
        'method'  => 'POST',
        'content' => http_build_query($data)
    )
);
$context  = stream_context_create($options);
$result = file_get_contents($url, false, $context);
if ($result === FALSE) { /* Handle error */ }

var_dump($result);

有关该方法和如何添加头的更多信息，请参阅PHP手册，例如:

stream_context_create: http://php.net/manual/en/function.stream-context-create.php

上面的答案对我不起作用。这是第一个完美运行的解决方案:

$sPD = "name=Jacob&bench=150"; // The POST Data
$aHTTP = array(
  'http' => // The wrapper to be used
    array(
    'method'  => 'POST', // Request Method
    // Request Headers Below
    'header'  => 'Content-type: application/x-www-form-urlencoded',
    'content' => $sPD
  )
);
$context = stream_context_create($aHTTP);
$contents = file_get_contents($sURL, false, $context);

echo $contents;
