问题正则表达模式寻找类似匹配

Question

I have one of the four patter:

"Test"
'Test'
`Test`
(Test)

Is it possible to get "Test" with a single preg_match call?

I tried the following:

if ( preg_match( '/^(?:"(.*)"|\'(.*)\'|`(.*)`|\((.*)\')$/iu', $pattern, $matches ) )

... but this gives me five elements of $matches back. But I would like to have two only (One for the whole match and one for the found match with "Test" in it.)

You can use dot to match the characters aroun d the word and use array_unique to remove duplicates.

preg_match_all("/.(\w+)./", $str,$match);
foreach($match as &$m) $m = array_unique($m);

var_dump($match);

array(2) {
  [0]=>
  array(4) {
    [0]=>
    string(6) ""Test""
    [1]=>
    string(6) "'Test'"
    [2]=>
    string(6) "`Test`"
    [3]=>
    string(6) "(Test)"
  }
  [1]=>
  &array(1) {
    [0]=>
    string(4) "Test"
  }
}
