使用正则表达式从链接获取子字符串[关闭]

Question

Need to get theme10 from catalog/view/theme/theme10/

I tried this:

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] ;

Works with and without / in the end.
