PHP method to find specified value in multidimensional array

This article mainly introduces the method of PHP to find a specific value in a multi-dimensional array. The example analyzes the related techniques of PHP to implement multi-dimensional array traversal and unset deletion. I hope to be helpful. The example in this article describes the method of finding a specific value in a multi-dimensional array in PHP. Share it with everyone for your reference.

The specifics are as follows:

Recently working on a project, you need to find whether a specific key and its corresponding specific value are contained in a multi-dimensional array, and clear the data, such as:

$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"）
)
)

Hope to achieve the effect: delete the record with id 2:

public function searchArray($array,$key,$value){
foreach($array as $keyp=>$valuep){
if($valuep[$key]==$value){
unset($array[$keyp]);
}
}
return $array;
}
