My Answer:
No, the `array_filter` function in PHP does not access array values by key. It only accesses array values by their index. If you need to filter an array based on key-value pairs, you can use a custom callback function with `array_filter` that checks the key-value pairs.

Here is an example of how you can filter an array based on key-value pairs using `array_filter`:

php

$array = array(

    'key1' => 'value1',

    'key2' => 'value2',

    'key3' => 'value3'

);



$filteredArray = array_filter($array, function($key, $value) {

    return $key == 'key2' && $value == 'value2';

}, ARRAY_FILTER_USE_BOTH);



print_r($filteredArray);

This will output:



Array

(

    [key2] => value2

)
