检查多维数组是否包含特定值[关闭]

Question

I have an array like this:

array(
    [0] => array("description" => "old, white, brown_hair", "name" => "jacques"),
    [1] => array("description" => "young, black, black_hair", "name" => "jack")
);

Now I want to check if the array contains jack. I tried this.

And this is my code.

You can use a simple foreach

foreach($arr as $k=>$arr1)
{
 if(in_array('jack',$arr1))
  {
    echo 'jack exists ! exiting....';
    break;
  }
}
