print array php

<?php
$a = array ('a' => 'apple', 'b' => 'banana', 'c' => array ('x', 'y', 'z'));
echo "<pre>";
print_r ($a);
echo "</pre>";
?>
  
Output:

(
    [a] => apple
    [b] => banana
    [c] => Array
        (
            [0] => x
            [1] => y
            [2] => z
        )
)

php echo array

function echo_arr($arr){
        for ($i=0; $i < count($arr); $i++) { 
                echo $arr[$i];
            }
        }

echo_arr($your_array_here);
