var_dump说bool但是返回一个字符串-php

i'm trying to check my email with curl.

我正试图用卷曲检查我的电子邮件。

I've got a function which connects to gmail:

我有一个连接到gmail的函数：

function check_email($url)
{ 
    // sendRequest 
    $curl = curl_init();
    curl_setopt($curl, CURLOPT_URL, $url);
    curl_setopt($curl, CURLOPT_FOLLOWLOCATION, 0);
    curl_setopt($curl, CURLOPT_RETURNTRANSFER, 0);
    $curlData = curl_exec($curl);
    curl_close($curl);

    //returning retrieved message
    return $curlData;
}

When I call the function and echo it ($email = check_email($ur); echo $email;), gmail sends me some html instead of showing the message:

当我调用该函数并回显它（$ email = check_email（$ ur）; echo $ email;）时，gmail会向我发送一些html而不是显示消息：

<HTML>
<HEAD>
<TITLE>Moved Temporarily</TITLE>
</HEAD>
<BODY BGCOLOR="#FFFFFF" TEXT="#000000">
<H1>Moved Temporarily</H1>
The document has moved <A HREF="-very large url-">here</A>.
</BODY>
</HTML>

so i want to then extract the "-very large url-" and curl to that, but when i var_dump($email) it says it's a bool! why is it returning html if it's a boolean and how can i get to the aforementioned html via php?

所以我想然后提取“-very large url-”并卷曲到那个，但是当我var_dump（$ email）它说它是一个bool！为什么它返回html如果它是一个布尔值，我怎么能通过PHP获得前面提到的HTML？

http://php.net/manual/en/function.curl-exec.php says

http://php.net/manual/en/function.curl-exec.php说

Returns TRUE on success or FALSE on failure. However, if the CURLOPT_RETURNTRANSFER option is set, it will return the result on success, FALSE on failure.

成功时返回TRUE，失败时返回FALSE。但是，如果设置了CURLOPT_RETURNTRANSFER选项，它将在成功时返回结果，在失败时返回FALSE。

Looks like you've got CURLOPT_RETURNTRANSFER set to 0 (false).

看起来你已经将CURLOPT_RETURNTRANSFER设置为0（false）。

http://php.net/manual/en/function.curl-setopt.php

#2

curl_setopt($curl, CURLOPT_RETURNTRANSFER, true);

Shall be used if you want curl_exec() to return anything other than boolean.

如果你想让curl_exec（）返回除boolean之外的任何东西，那么应该使用。
