Link 2 Arrary Random with each other

I am creating a 'Tips' section which changes on refresh. I had only text earlier but now there is an image associate with each tip.

I am randomising both arrays which is wrong. How do I link them?

It should be 'Tip 1' => '1.jpg', 'Tip 2' => '2.jpg', 'Tip 3' => '3.jpg'

Any suggestions would be highly appreciated.

<?php
    function array_random($arr, $num = 1) {
            shuffle($arr);

            $r = array();
            for ($i = 0; $i < $num; $i++) {
            $r[] = $arr[$i];
        }
         return $num == 1 ? $r[0] : $r;
    }

    $a = array(
        "Tip 1", 
        "Tip 2", 
        "Tip 3");

    $img = array(
        "1.jpg", 
        "2.jpg", 
        "3.jpg");
?>

Thank you.

Simply, join them in one array

$tips = array();
$tips[] = array("Tip" => "Tip text 1", "Image" => "Tip Image 1");
$tips[] = array("Tip" => "Tip text 2", "Image" => "Tip Image 2");
shuffle($tips);
echo $tips[0]['Tip']; // tip text
echo $tips[0]['Image']; // tip image

try this 

$new = array_combine($a,$img);    
shuffle($a);

echo $tip = $a[0];
echo $image = $new[$a[0]];
