     ) 

필자는 오직! 12.JPG로 끝납니다. 예상되는 결과의 예는 입니다. BuEZm5g! Wk ~ $ (KGrHqQH-DgEvrb2CLuOBL-vbkHlKw ~~ _12.JPG . 패턴을 가지고 있지만 잘 모르는 어떤 이유로 작동하지 않습니다.

 
$pattern = "/#\!(.*)_12.JPG/"; 

어떤 도움

Answer 1

하는 대신 '/#\!([^_]+)_12.JPG/'를 사용해보십시오. 또한, 당신은 바로?

,536을 preg_match_all를 사용하는

예 ..

<?php 
$input = '(that long string you have)'; 
$matches = array(); 
preg_match_all('/#\!([^_]+)_12.JPG/', $input, $matches); 
var_dump($matches); 

출력 (일치) $matches[0] 모든 전체 경기를 포함하고 $matches[1] 모든 _12.JPG까지 (그룹화 포함하는 방법을 알) ...

Answer 2

아니 정규식 문제에 미리 감사드립니다.

$names = explode('#', $names); 
$keep = array(); 

foreach ($names as $name) 
{ 
    if ((substr($name, 0, 1) == '!') && (substr($name, -6) == '12.JPG')) 
    { 
     $keep[] = $name; 
    } 
}
