使用正则表达式从链接获取子字符串

Question

需要从theme10

获取catalog/view/theme/theme10/

我试过了：

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] ;

最后使用/和不使用{{1}}。
