Source Code: Randomly Display Some Images From A Set of Images: PHP

(image.php)

"; ?>

Copy and paste above code into a plain text editor. Save the file with .php file extension. Make sure to have 5 image files(with .jpg extensions) in the same folder as image.php

PHP Code Explanation:

Arrays are very important concept in all programming language.

 $pic = array('1.jpg','2.jpg','3.jpg','4.jpg','5.jpg');

here $pic is an array variable and is used to store the file names of all the images.

shuffle($pic);

shuffle() is a standard PHP function, which shuffles the content of the array variable. i.e., it re-orders or changes the position of the elements of an array.

                           
                        ";
?>

Usually unordered listing tags of HTML displays elements vertically.

But using some css style property, we are showing the images horizontally.
i.e., display: inline;

for loop, loops through 0 to 3(in above example). After the execution of the above line of code(for one instance), we get the following HTML output in the browser.

\ (back slash) is used as an escape character, to escape the effect of “ (double quote).
