this is a very simple php randome image viewer

it all works and i hope you can understand it
it is so simple you should be troubled
_________________________________________________

<?php
//Make the image completely random.
srand((float) microtime() * 10000000);

//Array for the filenames.
$images = array("506254000_l.jpg", "493226254_l.jpg");

//Choose and image and echo it!
$image_key = array_rand($images);

//Just change the URL to the image location
echo '<img src="../images/'.$images[$image_key].'" border="0">';

?>

hope this is off help to people.. your Simple minded Genius Carnage

Hey

Nice Script. Would you mind making it a teeny bit more accessible in its output. Remove the border="0" attribute, ad an alt attribute and close the <img/> tag. The it will be perfect

I have a few suggestions as well.

0) Use code tags instead of quote tags. =)

1) It's no longer needed to seed the random functions, so the srand() call it a waste of resources.

2) Perhaps create the image array dynamically by listing all files in a directory, this would be much more newbie friendly than having a user edit the file. php.net/glob will be perfect for that.

ok notes take but hear me out

1: it is supposed to be fore the simple minded
2: it works fine as it is
3: i wrote it nearly 2 years ago
4: if you want it take it use and and adapt it

just let me know if you use it and i will be greatful

Hah, Carnidge Is Dumb, Just Playin Bro.

<?
function GetFiles($sdir){
   $files = array();
   $dir = opendir($sdir);
    while(($myfile = readdir($dir)) !== false){
        	if($myfile != '.' & $myfile != '..' & is_file($sdir."/".$myfile)){
            	$files[] = $myfile;
        	}else if($myfile != '.' & $myfile != '..' & is_dir($sdir."/".$myfile)){
				$filearr = GetFiles($sdir."/".$myfile);
					for($i=0;$i<count($filearr);$i++){
						$files[] = $sdir."/".$myfile."/".$filearr[$i];
					}
			}
    }
  closedir($dir);
  return $files;
}

$Files = GetFiles(".");
for($i=0;$i<count($Files);$i++){
echo $Files[$i]."<br/>";
}

?>

There is a script to get the files in the current and lower directories. HAIL Recursion. You will need to remove any non-image files from the array. A simple check can be done on each filename before it is added, this is a stimple string check.

Seems like an awful lot of code for such a simple task, perhaps http://www.php.net/glob could shorten it a bit. But hey, if it works then it works. =)

[Jamie]

The actual amount of is quite small, glob() could make it shorter I think if you were looking for a specific file type/name. My function just returns the entire contents of the directory including the contents of sub directories.

oh: ta for the glob tip never heard of it before.

make a file named image.txt and put links like this

::<img scr="http://abhisar.wen.ru/logo.gif" alt="logo"/>
::<img scr="http://krapwap.com/logo.gif" alt="logo"/>

now on page where you want to display random image insert the code

<?
$xfile = @file("image.txt");
$random_num = rand (0,count($xfile)-1);
$udata = explode("::",$xfile[$random_num]);
echo $udata[1]; //a random image from the text file will be displayed
?>

The only problem with that method is that it forced markup with content. which in my opinion is bad practice. It would be far better if image file names were stored externally to the markup. It would be far easier to maintain also, In your scenarios a user would have to upload a new image and create a new entry in image.txt. In a scenario using my code all the user has to do is upload a new image into the image directory and hey presto the script can use it.
