Easy php help

[jzhang1013]

Hey all so what I want to do is basically write a php code that pulls all my images from a certain folder filled with images and display them. Can someone write me a simple code that does that?

Thanks,
John

<?php
$files = glob("images/*.*");
for ($i=1; $i<count($files); $i++)
{
$num = $files[$i];
echo '<img src="'.$num.'" alt="random image">'."&nbsp;&nbsp;";
}
?>

hey thanks! now where in that code would I specify the folder name? or does this code have to be put in the same folder as the images its grabbing?

In the second line

$files = glob("images/*.*");
I am asuming your the image folder is titled "images", therefore if it is really titled "gobbeldygoop" the second line would be as so:

$files = glob("gobbeldygoop/*.*");

Best Regards

It will display all format images compatable with the browsers. ie: I'am not sure but adobe illiustrator images can be displayed on a webpage when using Firefox but I'am not sure.

But generally speaking to cover 98% of web browsers, this script will display .JPG, .GIF, .PNG and .BMP files

EDIT: I just tested the script and discovered that it will only display images DIRECTLY in the folder specified by the script. It will not display any images in subfolders.

so i tried it and im getting this error..

Parse error: syntax error, unexpected ';' in /home/jzhang/public_html/testgrab/testgrab.php on line 3

Make sure you have copied it exactly as I have written, the absolute only thing that you need to change is the foldername betwen the quotation markes on line two. An error msg like that usually indicates a typo from either typing it in by hand too fast or maybe you messed something up when you altered the folder name in line 2

do i have to rename my images to 1, 2, 3, etc?

No, this will just go through all the files that the glob() function finds by using count(). It just uses $i as an index so it can go through a loop looking for each file.

You can name the files whatever you want.

If you wanted to make it more specific, for example if you have some files in the images folder that aren't images then you could put, for example:
glob("images/*.jpg");
