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);

使用此脚本，我得到输出：     http://website.com/632383970568166e82391f.png

我需要提取ID，这是abcdef并在另一个调用中使用它。我怎样才能做到这一点？

Answer 1

使用正则表达式或执行此操作：

$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];

Answer 2

Simple regex

$re = "/\\S+\\/([\\S]+)_/"; 
$str = "http://subdomain.website.com/something/folder1/folder2/folder3/folder4/folder5/20385425_632383970568166e82391f.png"; 

preg_match($re, $str, $matches);
