您可以尝试这一点，但也确保收听网址有一个处理程序来处理你的字preSS请求端（使用 GET methof）

 函数curlAdduser（$ strUrl）
{
    如果（空（$ strUrl））
    {
        回报错误：无效的URL给';
    }    $ CH = curl_init（）;
    curl_setopt（$ CH，CURLOPT_URL，$ strUrl）;
    curl_setopt（$ CH，CURLOPT_RETURNTRANSFER，1）;
    curl_setopt（$ CH，CURLOPT_CONNECTTIMEOUT，30）;
    curl_setopt（$ CH，CURLOPT_CUSTOMREQUEST，'GET'）;
    $收益率= curl_exec（$ CH）;
    curl_close（$ CH）;
    返回$返回;
}
 

从外部站点调用函数：

curlAdduser(\"www.example.com/adduser?username=james&password=simpletext&email=myemail\");

更新：是 POST 法

 函数curlAdduser（$ strUrl，$数据）{
    $栏='';
    的foreach（$数据，$关键=＆GT; $值）{
        $领域。= $键。 =。 $值。 '和;';
    }
    $栏= RTRIM（$领域，'和;'）;    $ CH = curl_init（）;
    curl_setopt（$ CH，CURLOPT_URL，$ strUrl）;
    curl_setopt（$ CH，CURLOPT_RETURNTRANSFER，1）;
    curl_setopt（$ CH，CURLOPT_CONNECTTIMEOUT，30）;
    curl_setopt（$ CH，CURLOPT_POST，1）;
    curl_setopt（$ CH，CURLOPT_POSTFIELDS，$领域）;
    $收益率= curl_exec（$ CH）;
    curl_close（$ CH）;
    返回$返回;
}
 

通话与数据的功能

  $数据=阵列（
    用户名= GT; 詹姆斯，
    密码=＆GT; 的SimpleText
    电子邮件=＆GT; 我的电子邮件
）;
curlAdduser（www.example.com/adduser，$数据）;
 

In Wordpress, i want to create New Users from external. I've found this is function in wordpress:

wp_create_user( $username, $password, $email );

So how can i run this function from external call please?

I mean, how to run this function from either:

• Via simple URL with GET, like: www.example.com/adduser/?username=james&password=simpletext&email=myemail
• Via cURL with POST

.. from external website.

You may try this but also make sure that the listening url has a handler to handle the request in your WordPress end (using GET methof)

function curlAdduser($strUrl)
{
    if( empty($strUrl) )
    {
        return 'Error: invalid Url given';
    }

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $strUrl);
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
    curl_setopt($ch, CURLOPT_CUSTOMREQUEST, 'GET');
    $return = curl_exec($ch);
    curl_close($ch);
    return $return;
}

Call the function from external site :

curlAdduser("www.example.com/adduser?username=james&password=simpletext&email=myemail");

Update : using POST method

function curlAdduser($strUrl, $data) {
    $fields = '';
    foreach($data as $key => $value) { 
        $fields .= $key . '=' . $value . '&'; 
    }
    $fields = rtrim($fields, '&');

    $ch = curl_init();
    curl_setopt($ch, CURLOPT_URL, $strUrl);  
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_CONNECTTIMEOUT, 30);
    curl_setopt($ch, CURLOPT_POST, 1);
    curl_setopt($ch, CURLOPT_POSTFIELDS, $fields);
    $return = curl_exec($ch);
    curl_close($ch);
    return $return;
}

Call the function with data

$data = array(
    "username" => "james",
    "password" => "simpletext",
    "email" => "myemail"
);
curlAdduser("www.example.com/adduser", $data);
