filter of associative array with dynamic filter-CodePudding

I am beginner with php.

I have two Assosiative Arrays , first is users

I have users associative Array like this

$users = array(
  0 => array(
    "name" => "ali",
    "age" => 22,
    "score" => 12
  ),
  1 => array(
    "name" => "hasan",
    "age" => 32,
    "score" => 52
  ),
);

Also , I have a Filter Array like this , that elements count is not fixed , for example "age" can exist or not ! and also others

$filters = array(
  "name" => "ali",
  "age" => 22
);

I need to filter this array dynamically depending on this $filters

function filterFunc($item)
{

  // i dont how what should write here
}
$filtered_users = array_filter($users, 'filter');

But , I don't know how to do it ?

CodePudding user response：

To filter, you need to iterate over all the filters in the filterFunc callback function and check if the filter applies. If one does not apply return false immediatly, else return true:

<?php

$users = array(
    0 => array(
    "name" => "ali",
    "age" => 22,
    "score" => 12
    ),
    1 => array(
    "name" => "hasan",
    "age" => 32,
    "score" => 52
    ),
);

$filters = array(
    "name" => "ali",
    "age" => 22
);

function filterFunc($item) {
    global $filters;
    foreach ($filters as $key => $value) {
        if ($item[$key] != $value) {
            return false;
        }
    }
    return true;
}
$filtered_users = array_filter($users, "filterFunc");   
print_r($filtered_users);

?>
