How to implement multi-dimensional array traversal and unset deletion in PHP

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.
