This article mainly introduces how to implement multi-dimensional array traversal and unset deletion in PHP. Interested friends can refer to it. I hope it will be helpful to everyone.
I am working on a project recently. I need to find out whether a specific key and its corresponding specific value are contained in a multi-dimensional array, and clear the data. For example:
$arr = array( //为了看的方便,数组表达形式不对 0=>array(id =>1,name =>"li") 1=>array(id =>2,name =>"na") 2=>array(id =>3,name =>"na") ) )
I hope to achieve the effect: delete the id as The record of 2:
public function searchArray($array,$key,$value){ foreach($array as $keyp=>$valuep){ if($valuep[$key]==$value){ unset($array[$keyp]); } } return $array; }
Summary: The above is the entire content of this article, I hope it will be helpful to everyone's study.
