Question

A folder on my server holds a variable number of images. I’m working on a PHP script that is intended to retrieve the entire list of files there (a list of filenames) and create an associative array like so:

$list = array(1=>"image1.png", 2=>"image2.png", ...);

Basically, the list vector starts as empty and when a new image is found, its name has to be added to the list, with an incremented index: i=>”image[i].png”

How do I go about achieving this? Or in other words, how do I push a new element to my array?

I’m not sure why you are referring to this as an associative-array, but if you want to add somethign to an array, do it like this

   $list = array();
   $list[] = "image1.png";
   $list[] = ....;
   $list[] = "imagei.png";
