PHP数组搜索特定值

这是我的$数组的结果：

    Array ( [row] => Array ( [Field] => product_id [Type] => int(11) [Null] => NO [Key] => PRI [Default] => [Extra] => auto_increment ) [rows] => Array ( [0] => Array ( [Field] => product_id [Type] => int(11) [Null] => NO [Key] => PRI [Default] => [Extra] => auto_increment ) [1] => Array ( [Field] => model [Type] => varchar(64) [Null] => NO [Key] => [Default] => [Extra] => ) [2] => Array ( [Field] => sku [Type] => varchar(64) [Null] => NO [Key] => [Default] => [Extra] => ) [3] => Array ( [Field] => upc [Type] => varchar(12) [Null] => NO [Key] => [Default] => [Extra] => ) [4] => Array ( [Field] => ean [Type] => varchar(14) [Null] => NO [Key] => [Default] => [Extra] => ) [5] => Array ( [Field] => jan [Type] => varchar(13) [Null] => NO [Key] => [Default] => [Extra] => ) [6] => Array ( [Field] => isbn [Type] => varchar(13) [Null] => NO [Key] => [Default] => [Extra] => ) [7] => Array ( [Field] => mpn [Type] => varchar(64) [Null] => NO [Key] => [Default] => [Extra] => ) [8] => Array ( [Field] => location [Type] => varchar(128) [Null] => NO [Key] => [Default] => [Extra] => ) [9] => Array ( [Field] => quantity [Type] => int(4) [Null] => NO [Key] => [Default] => 0 [Extra] => ) [10] => Array ( [Field] => stock_status_id [Type] => int(11) [Null] => NO [Key] => [Default] => [Extra] => ) [11] => Array ( [Field] => image [Type] => varchar(255) [Null] => YES [Key] => [Default] => [Extra] => ) [12] => Array ( [Field] => manufacturer_id [Type] => int(11) [Null] => NO [Key] => [Default] => [Extra] => ) [13] => Array ( [Field] => shipping [Type] => tinyint(1) [Null] => NO [Key] => [Default] => 1 [Extra] => ) [14] => Array ( [Field] => price [Type] => decimal(15,4) [Null] => NO [Key] => [Default] => 0.0000 [Extra] => ) [15] => Array ( [Field] => points [Type] => int(8) [Null] => NO [Key] => [Default] => 0 [Extra] => ) [16] => Array ( [Field] => tax_class_id [Type] => int(11) [Null] => NO [Key] => [Default] => [Extra] => ) [17] => Array ( [Field] => date_available [Type] => date [Null] => NO [Key] => [Default] => [Extra] => ) [18] => Array ( [Field] => weight [Type] => decimal(15,8) [Null] => NO [Key] => [Default] => 0.00000000 [Extra] => ) [19] => Array ( [Field] => weight_class_id [Type] => int(11) [Null] => NO [Key] => [Default] => 0 [Extra] => ) [20] => Array ( [Field] => length [Type] => decimal(15,8) [Null] => NO [Key] => [Default] => 0.00000000 [Extra] => ) [21] => Array ( [Field] => width [Type] => decimal(15,8) [Null] => NO [Key] => [Default] => 0.00000000 [Extra] => ) [22] => Array ( [Field] => height [Type] => decimal(15,8) [Null] => NO [Key] => [Default] => 0.00000000 [Extra] => ) [23] => Array ( [Field] => length_class_id [Type] => int(11) [Null] => NO [Key] => [Default] => 0 [Extra] => ) [24] => Array ( [Field] => subtract [Type] => tinyint(1) [Null] => NO [Key] => [Default] => 1 [Extra] => ) [25] => Array ( [Field] => minimum [Type] => int(11) [Null] => NO [Key] => [Default] => 1 [Extra] => ) [26] => Array ( [Field] => sort_order [Type] => int(11) [Null] => NO [Key] => [Default] => 0 [Extra] => ) [27] => Array ( [Field] => status [Type] => tinyint(1) [Null] => NO [Key] => [Default] => 0 [Extra] => ) [28] => Array ( [Field] => serial [Type] => tinyint(1) [Null] => NO [Key] => [Default] => 0 [Extra] => ) [29] => Array ( [Field] => serialn [Type] => varchar(64) [Null] => NO [Key] => [Default] => [Extra] => ) [30] => Array ( [Field] => date_added [Type] => datetime [Null] => NO [Key] => [Default] => 0000-00-00 00:00:00 [Extra] => ) [31] => Array ( [Field] => date_modified [Type] => datetime [Null] => NO [Key] => [Default] => 0000-00-00 00:00:00 [Extra] => ) [32] => Array ( [Field] => viewed [Type] => int(5) [Null] => NO [Key] => [Default] => 0 [Extra] => ) ) [num_rows] => 33 ) 

如果找到“序列号”，我该如何搜索？做些什么，如果找不到，然后再做其他事情

我试过这个

    if(array_search('serial',$array)) { echo "hello"; } else { echo "heheheh";}

但它并没有达到我想要的效果？

试试这个

  foreach( $array['rows'] as $array1  ){
    if( array_search('serial', $array) ){
        do something here
    }
  }

serial

是子数组中的值。因此，

array\u search（）

单独使用是不起作用的。是的，谢谢你一针见血，我知道这很容易，只是大脑衰退了。这是为我工作的代码：foreach（$array['rows']as$array1）{if（array_search（'serial'，$array））{dosomethine here break；}else{dothis}
