php - 使用正则表达式从链接中获取子字符串

Question

需要theme10从catalog/view/theme/theme10/

我试过这个：

preg_match('|catalog/view/theme/(.*)/|',$html, $theme);

Answer 1

$matches = [] ;
$pattern = "@catalog/view/theme/([a-zA-Z0-9]+)/{0,1}@" ;
$string = "catalog/view/theme/theme10" ;

preg_match($pattern, $string, $matches) ;

echo $matches[1] ;

最终有无/工作。
