与php

Question

我试图在php（laravel框架）中使用foreach循环匹配两个字符串。

$c_act = "ABC123";
foreach ($codes as $cd) {
      $ac = $cd->Code;       //ac holds our Activity code

      if ($ac==$c_act) {
           $act_id = $cd->ID; 
        }
}

此处$codes通过ID和Code保存我的值数据。

 [{"ID":"7","Code":"ABC-1"},{"ID":"8","Code":"ABC-OBT"},{"ID":"12","Code":"ABCD"}]

如果第一个变量不匹配，那么我需要回到foreach循环并从我拥有的下一个值开始。我试过了，但无法完成它。
如何使用php做到这一点？

尝试使用此代码：

$act_id = null;
$c_act = "ABC123";
foreach ($codes as $cd) {
    $ac = $cd->Code;       //ac holds our Activity code
    if ($ac==$c_act) {
        $act_id = $cd->ID;
        break;
    }
}

if($act_id === null){
    // there was no match
}else{
    // there was a match, and the ID is stored in $act_id
}
