PHP和cURL从头部提取变量

Question

    $response = curl_exec($ch);
    preg_match_all('/^Location:(.*)$/mi', $response, $matches);
    curl_close($ch);

Using this script, I get the output: http://website.com/632383970568166e82391f.png

And I need to extract the ID, which is abcdef and use it in another call. How can I do that?

Answer 1

Use regular expressions or do this:

$url = "http://subdomain.website.com/something/folder1/folder2/folder3/folder4/folder5/20385425_632383970568166e82391f.png";
$urlParts = explode('/', $url)
$imgFileParts = explode('_', $urlParts[(count($urlParts) - 1)]);

$imgId = $imgFileParts[0];
