PHP Random Images Function

[Guest]

I had made a php random image function and the problem I have at this moment is I don't want to change the "4" number to a "5" because I included another image. Is there a value where the "4" is some php function so I do not need to always update?

<?php
$roll = rand(1,4);
print "<img src = randImages/Bn$roll.jpg>";
?>

Thank you,

You could try something like this:

<?php
$path = $_SERVER['DOCUMENT_ROOT'].'/randImages';
$roll = rand(1, count(glob("$path/*.jpg"));
print "<img src='/randImages/Bn$roll.jpg' alt='...'>\n";
?>

glob() searches a given directory for filenames matching the wildcard
pattern (in this case *.jpg). It returns an array with all found
filenames. count() then simply returns the array's size and passes it to
rand().
