PHP-强制不要忽略preg_match_all中的相同值

Question

我在使用preg_match_all函数时遇到问题，默认情况下该函数会自动忽略相同的值。

码：

$data = '<img src="images/smiles/lol.gif" alt="Laughing" border="0">  <img src="images/smiles/lol.gif" alt="Laughing" border="0">  <img src="images/smiles/lol.gif" alt="Laughing" border="0">';
preg_match_all('#<img src="images/smiles/(.+?)" alt=".+" border="0">#',$data,$out);
print_r($out);

结果：

Array
(
    [0] => Array
        (
            [0] => <img src="images/smiles/lol.gif" alt="Laughing" border="0">  <img src="images/smiles/lol.gif" alt="Laughing" border="0">  <img src="images/smiles/lol.gif" alt="Laughing" border="0">
        )

    [1] => Array
        (
            [0] => lol.gif
        )

)

我希望$out变量是这样的：

Array
(
    [0] => Array
        (
            [0] => <img src="images/smiles/lol.gif" alt="Laughing" border="0">
            [1] => <img src="images/smiles/lol.gif" alt="Laughing" border="0">
            [2] => <img src="images/smiles/lol.gif" alt="Laughing" border="0">
        )

    [1] => Array
        (
            [0] => lol.gif
            [1] => lol.gif
            [2] => lol.gif
        )

)

我应该添加或更改哪个标志或参数以具有上述输出？ 提前致谢！

编辑

当然，我在$data变量中不仅只有这些HTML标记，还有一些其他标记和文本。

尝试这个：

$data = '<img src="images/smiles/lol.gif" alt="Laughing" border="0">  <img src="images/smiles/lol.gif" alt="Laughing" border="0">  <img src="images/smiles/lol.gif" alt="Laughing" border="0">';
preg_match_all('#<img[^>]+src\\s*=\\s*[\'"]images/smiles/([^\'"]+)[\'"][^>]*>#i', $data, $out);
var_dump($out);

输出为：

array
  0 => 
    array
      0 => string '<img src="images/smiles/lol.gif" alt="Laughing" border="0">' (length=59)
      1 => string '<img src="images/smiles/lol.gif" alt="Laughing" border="0">' (length=59)
      2 => string '<img src="images/smiles/lol.gif" alt="Laughing" border="0">' (length=59)
  1 => 
    array
      0 => string 'lol.gif' (length=7)
      1 => string 'lol.gif' (length=7)
      2 => string 'lol.gif' (length=7)
