随机 URL 文件获取内容 PHP

Question

i was trying to rotate url using file get content but there's little error which I am not able to figure out.

    <?php
    //Rotate
$urls = array();
$divs[] = '/fun.jpg';
$divs[] = '/nuf.jpg';

echo file_get_contents(src="'. $divs[rand(0, count($divs)-1)] .'");

    ?>

But it's not returning any random div.

Answer 1

Well, if you just show images from same folder, as your PHP script is in, you should be able to do it like this. ( did not test it )

<?php
header("Content-Type: image/jpg");

$divs[] = 'fun.jpg';
$divs[] = 'nuf.jpg';

echo file_get_contents($divs[array_rand($divs)]);
?>

You need to include header: Show image using file_get_contents

And for picking random key from array you can use array_rand() function: https://www.php.net/manual/en/function.array-rand.php
