[support] How to show random image files in webpage

[Austin Einter]

Hi All
I would like to show image files (in a random manner) at the top of webpage.
I want to have a folder that contains all the image files.

Then I want to have a separate php file (say rotate.php) having logic of
selecting the random image file.
And want to include that rotate.php file from page.tpl.php.

To start with, I followed the marinelli view.
Used the images and rotate.php (\marinelli\img\banners\rotate.php).

Copied to image files and rotate.php to path where my page.tpl.php is
present.

In page.tpl.php, I added the line  include ("rotate.php");

The rotate.php looks as below. On debugging looks *preg_match *line it
breaks.
Please let me know why line "if ( preg_match( $regex, $file ) ) {" breaks.

Regards
Austin

*<?php*

*/***

** randomly select an image from the current directory and return it*

***

** @todo - consider accepting a local path as $_GET['img'] for overrides*

** to remain compatible with Marinelli's rotate.php*

** *

** (but why? why possible use case is there for linking to *

** rotate.php?img=file.gif instead of straight to file.gif?)*

**/*

*$file_types = array( *

*'gif' => 'image/gif',*

*'jpg' => 'image/jpeg',*

*'jpeg' => 'image/jpeg',*

*'png' => 'image/png'*

*) ;*

*$regex = '/\.(' . implode('|',array_keys($file_types)) . ')$/i' ;*

*$files = array() ;*

*$directory = opendir(".");*

*while ( FALSE !== ($file = readdir( $directory )) ) {*

*if ( preg_match( $regex, $file ) ) {*

*$files[] = $file ;*

*}*

*}*

*if ( !empty( $files ) ) {*

*$which = rand(0,sizeof($files)-1) ;*

*if ( $file = file_get_contents( $files[$which] ) ) {*

*$parts = explode('.',$files[$which]) ;*

*$ext = strtolower($parts[sizeof($parts)-1]) ;*

**

*header( "Content-type: " . $file_types[$ext] ) ;*

*header( "Expires: Wed, 29 Jan 1975 04:15:00 GMT" );*

*header( "Last-Modified: " . gmdate("D, d M Y H:i:s") . " GMT" );*

*header( "Cache-Control: no-cache, must-revalidate" );*

*header( "Pragma: no-cache" );*

*print $file ;*
