<iframe src="https://player.vimeo.com/video/322332324?byline=0" width="640" height="360" frameborder="0" webkitallowfullscreen mozallowfullscreen allowfullscreen></iframe>

我需要从src中提取数字..我需要得到322332324.无论有多少位数。

此代码将获取src，但如何获取数字

preg_match（＆＃39; / src =＆＃34;（[^＆＃34;] +）＆＃34; /＆＃39;，$ iframe_string，$ match）; $ url = $ match [1];

Answer 1

假设数字始终是URL的最后一部分，您可以这样做：

备选方案1

$url = 'https://player.vimeo.com/video/322332324?byline=0';

// Extract the path from the URL
$path = parse_url($url, PHP_URL_PATH);

// Explode the path on / to get the different fragments
$fragments = explode('/', $path);

// Now simply take the last part of the fragemnts
$numbers = end($fragments);

备选方案2

如果你想要更少的代码，你可以跳过爆炸部分，只有substr（）和strrpos（）。代码少但冗长：

$url = 'https://player.vimeo.com/video/322332324?byline=0';

// Get the path from the URL
$path = parse_url($url, PHP_URL_PATH);

// Get the everything after the last slash
$numbers = substr($path, strrpos($path, '/') + 1);
