How to use array_keys Function to Access Keys and Values In PHP

In this new approach, we will use the array_keys function to access the keys directly and then use those keys to access the corresponding values.

Example : In this example we retrieves array keys using array_keys and iterates over them with foreach, printing each key and its corresponding value from the $markSheet array.

PHP
<?php 
$markSheet = array("Nikunj" => 45, "Dhruv" => 78, "Yash" => 93, "Arti" => 69); 

$keys = array_keys($markSheet); // Get all keys of the array

foreach ($keys as $key) {
    echo "$key - $markSheet[$key] \n";
} 
?> 

Output
Nikunj - 45 
Dhruv - 78 
Yash - 93 
Arti - 69
