用cURL重写file_get_content函数

Question

So I have this function which I'm trying to make with cURL because of server securities file_get_contents() is disabled.

$url ='https://example.com' .

        '/b/'.urlencode($this->user_ID).'/o/'.urlencode($this->ID);
        $url=$url.'/h/'.urlencode($hash);
        $number=rand(0, 10)/10 ."";
        $url=$url.$number;

    $html = file_get_contents($url);
    preg_match('/<td valign="bottom" class="sum">(.*?)<\/td\>/', $html , $matches);
    return $matches[0];

What I have now is this

$url ='https://example.com' .

     '/b/'.urlencode($this->user_ID).'/o/'.urlencode($this->ID);
    $number=rand(0, 10)/10 ."";

    $url=$url.$number;
    $ch = curl_init();
    curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
    curl_setopt($ch, CURLOPT_URL, $url);
    curl_setopt($ch, CURLOPT_SSL_VERIFYHOST, false);
    curl_setopt($ch, CURLOPT_SSL_VERIFYPEER, false);
    $matches = curl_exec($ch);
    curl_close($ch);

    $html = file_get_contents($url);
    preg_match('/<td valign="bottom" class="sum">(.*?)<\/td\>/', $html , $matches);
    return $matches[0];

Is it something like this or I'm totally on wrong way? And how to change now this line - $html = file_get_contents($url); ?

Answer 1

You must remove the call to file_get_contents after the curl, you already have the response from the curl request.

replace this

$matches = curl_exec($ch);

with this

$html = curl_exec($ch);

Then do preg_match on the response

// $html = file_get_contents($url); this line is not needed
preg_match('/<td valign="bottom" class="sum">(.*?)<\/td\>/', $html , $matches);
return $matches[0];

Finally, inspect the contents of $matches and $matches[0]
