Php implements the method of searching for specific values in multi-dimensional arrays.

This example describes how php can find a specific value in a multi-dimensional array. Share it with you for your reference. The details are as follows:

For a recent project, you need to find out whether a specific key and its corresponding value from the multi-dimensional array, and clear the data, such:

$ Arr = array (// For convenience, the array expression is not 0 => array (id => 1, name => "li ") 1 => array (id => 2, name => "na") 2 => array (id => 3, name => "na ")))

Expected results: 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 ;}

I hope this article will help you with php programming.
