Problem with stristr - very basic error?

[phpdeano]

Hi,

I have
<pre>
$dirHandle=opendir('c:\phpdev\www\starinthecar\gallery\spgm\gal\Gallery');

while ($file = readdir($dirHandle))

{

if (stristr($file, ".jpg"))

{

echo "<center><table border=1 width=300><tr><td width=100><font face=verdana size=2><a href=http://200.200.1.3/starinthecar/comments/comments.php?filename=",$file,"><img src=http://200.200.1.3/starinthecar/gallery/spgm/gal/Gallery/thb",$file,"></A></font></td><td width=200><font face=verdana size=2>",$file,"</font></tr></table></center>";

}

}
closedir($dirHandle);
</pre>
which looks through my directory and displys thumbnails to pass to another page.

The problem is the folder also has .jpg.cmt files and Jpg's that start with thb that I do not want displayed.

I am so confused, could someone tell me which functions to use to just get a list of files that do not start with thb and do not end with .jpg.cmt. I just want the jpg's.

Help appreciated

try substr($file, -3), this will return the last 3 character of $file

example:

$file = "http://www.phpbuilder.com/images/new-logo.gif";

if(substr($file, -3) == "gif")
  echo "Its a gif file.";

Thanks, however I finallly worked it out.

I used

if (stristr($file, ".jpg")) XOR if (stristr($file, thb")) XOR if (stristr($file, ".cmt"))

And that worked fine.

A faster-running solution would be

if((substr($file,-4)=='.jpg') && (substr($file,0,5)!='_thb_'))

In other words, the test succeeds only if the last four characters are ".jpg" and the first five are not "thb".
