I have one directory called images/tips.

Now in that directory I have many images which can change.

I want the PHP script to read the directory, to find the images, and out of those images found to pick a random image.

Any idea on how to do this?


$imagesDir = 'images/tips/';

$images = glob($imagesDir . '*.{jpg,jpeg,png,gif}', GLOB_BRACE);

$randomImage = $images[array_rand($images)]; // See comments

You can send a 2nd argument to array_rand() to get more than 1.

You should point to your vendor/autoload.php at Settings | PHP | PHPUnit when using PHPUnit via Composer.

This blog post has all the details (with pictures) to successfully configure IDE for such scenario:

On Mac OS X environment variables available in Terminal and for the normal applications can be different, check the related question for the solution how to make them similar.

Note that this solution will not work on Mountain Lion (10.8).

Get rid of the


otherwise PHPExcel has no way of knowing whether a cell is formatted as a date or not

setReadDataOnly(true) tells PHPExcel to load only the raw data from each cell. As the only way MS Excel differentiates a date/time from a float is through the number format mask (not from the raw data), and you're telling PHPExcel not to read the number format masks, PHPExcel can't tell the diference, so all floats are simply treated as floats

You can use glob

$images = glob('/tmp/*.{jpeg,gif,png}', GLOB_BRACE);

If you need this to be case-insensitive, you could use a DirectoryIterator in combination with a RegexIterator or pass the result of scandir to array_map and use a callback that filters any unwanted extensions. Whether you use strpos, fnmatch or pathinfo to get the extension is up to you.
