像jQuery AJAX在PHP中一樣從URL獲取數據

Question

我想通過發送一些POST數據來獲取URL的數據。 簡而言之，當jQuery AJAX獲取數據時，我希望在PHP中獲得數據。 此代碼類似於PHP。

$.ajax({
    url: "http://example.com/",
    type: "POST",
    data: data,
    dataType: 'json',
    success: function (result) {
        alert(result);
    }
});

您需要為此使用curl 。 大衛·沃爾什（Davidwalsh） 在此提供了一個很棒的教程

//extract data from the post
//set POST variables
$url = 'http://domain.com/get-post.php';
$fields = array(
    'lname' => urlencode($_POST['last_name']),
    'fname' => urlencode($_POST['first_name']),
    'title' => urlencode($_POST['title']),
    'company' => urlencode($_POST['institution']),
    'age' => urlencode($_POST['age']),
    'email' => urlencode($_POST['email']),
    'phone' => urlencode($_POST['phone'])
);

//url-ify the data for the POST
foreach($fields as $key=>$value) { $fields_string .= $key.'='.$value.'&'; }
rtrim($fields_string, '&');

//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, count($fields));
curl_setopt($ch,CURLOPT_POSTFIELDS, $fields_string);

//execute post
$result = curl_exec($ch);

//close connection
curl_close($ch);
