在PHP中获取URL内的整数

Suppose I am reading a web page and the URL is "http://example.com/term/11,23". How can I use PHP to get ONLY the integer in the URL?

You can do this way:

$str = 'http://example.com/term/11,23';
echo end(explode('/', $str));

Result:

11,23

<?php
$url = 'http://example.com/term/11,23';
preg_match_all('#(\d+)#', $url, $matches);
print_r($matches); //outputs array([0]=>11,[1]=>23)
?>
