Show images based on String-CodePudding

i want my code to show certain images based on a given string like "Brand1,Brand2,Brand3" I already declared the images with:

<?php
  $brandString ="Brand1,Brand2,Brand3";

 $images = [
    'Brand1' => 'Brand1.png',
    'Brand2' => 'Brand2.png',
    'Brand3' => 'Brand3.png',
    'Brand4' => 'Brand4.png'
];

Now I only want to show the images that are declared in the string. What is the best way to do this?

CodePudding user response：

Using explode, you can split the string into an array on every occurance of a comma. That way you can just run through your brand array by using foreach.

So, using your example it would look something like this:

<?php
 $brandString ="Brand1,Brand2,Brand3";
 $brandArray = explode(",", $brandString);
 $images = [
    'Brand1' => 'Brand1.png',
    'Brand2' => 'Brand2.png',
    'Brand3' => 'Brand3.png',
    'Brand4' => 'Brand4.png'
];

foreach($brandArray AS $brand) {
echo $images[$brand]; //this would print out the image names in order: Brand1.jpg, Brand2.jpg, Brand3.jpg
}
