Preg_match捕获两个大写字母，3个数字和2个大写字母，以及超过7个数字 - preg_match capturing two capital letters, 3 digits and 2 capital letters, and than 7 digits

preg_match capturing two capital letters, 3 digits and 2 capital letters, and than 7 digits

现在我有了下面的字符串

"IG 449WW 6180262 250"

我想匹配前两个字母，然后是第二个5个字母和数字，然后是7个数字，我想捕获每一个。

所以我有以下preg_match:

  $scanned_barcode = trim(Input::get('barcode'));
    if (preg_match("/([A-Z]{2})'s('d{3}[A-Z]{2})'s('d{7})/", $scanned_barcode, $found)) {
        $mfg_id    = $found[1];
        $game_code = $found[2];
        $serial    = Game::find($found[3]);
}

我这样做对吗?我是不是漏掉了什么?有更好的方法吗?

您的正则表达式可以工作，但这样做会更容易:

<?php
    $scanned_barcode = trim(Input::get('barcode'));
    // 'explode' the string into an array(), using the space as the delimiter
    // http://php.net/manual/en/function.explode.php
    $found = explode(' ', $scanned_barcode);
    $mfg_id    = $found[0];
    $game_code = $found[1];
    $serial    = Game::find($found[2]);
?>
