是否存在删除多维数组行的PHP本机方法？

Question

For example, i have the following multidimensional array (an array of associative arrays):

array(
[0]=> (array('key01'=>'value01', 'key02'=>'value02')),
[1]=> (array('key11'=>'value11', 'key12'=>'value12')),
[2]=> (array('key21'=>'value21', 'key22'=>'value22')),
...
[N]=> (array('keyN1'=>'valueN1','keyN2'=>'valueN2'))
);

I'm looking for a native method (if exists) that find a value in that array and remove the corresponding row. For example, i would remove row that contains value value21, the resulting array is the following:

array(
[0]=> (array('key01'=>'value01', 'key02'=>'value02')),
[1]=> (array('key11'=>'value11', 'key12'=>'value12')),
...
[N]=> (array('keyN1'=>'valueN1','keyN2'=>'valueN2'))
);

(i would not use for loops if possible...)

Answer 1

You can use array_filter() with closure to achieve this.

    $myArr = array(
            array('key01'=>'value01', 'key02'=>'value02'),
            array('key11'=>'value11', 'key12'=>'value12'),
            array('key21'=>'value21', 'key22'=>'value22'),
    );


    $finalArr = array_filter($myArr,function($val1){
                      $flag = true;
                      array_filter($val1,function($val2) use(&$flag){
                               if($val2 == 'value21'){
                                     $flag=false;
                               }
                      });

                      return $flag;
                });

    $finalArr = array_values($finalArr); // to get the array numerically indexed in order

But I will have to say that doing a nested foreach with unset() is almost similar. Hope it helps.

Edit:

in_array() in the closure is much simpler

$finalArr = array_filter($myArr,function($val1){
                  return ! in_array("value21",$val1);
            });

Also remember that there is no use of closure here rather lambda, both of them are anonymous functions.
