Directory listing question

[lowtide]

I am using the following code to extract the images from a directory and place them in a table. It works fine except that the "." and ".." lines from the directory are also read as seperate files. I only want it to show .gif and .jpgs.: <br>
$ptr=opendir($path.$sport); <br>
while ($file = readdir($ptr)){ <br>
print "&lt;TR align=\"left\" valign=\"top\"&gt;&lt;TD&gt;&lt;img src=\"

http://$virtual/$sport/$file\"

width=\"75\" height=\"100\" border=\"0\"&gt;&lt;/a&gt;&lt;input type=\"radio\" name=\"imgpick\" value=\"

http://$virtual/$sport/$file\"&gt;&lt;/TD&gt;&lt;/TR&gt;";

<br>
} <br>
closedir($ptr);

Have you tried doing an IF inside the while loop which checks if the $file is not "." and ".."? I don't think you can restrict the listing in the opendir command.<br>
<br>
try something like:<br>
<br>
if (strcmp(".", $file) AND strcmp("..",$file))<br>
{<br>
print ...<br>
}

This is the way I've done it in Perl. Perhaps there is an equivalent method in PHP. Just a PHP newbie right now so I can't say definitively.<br>
<br>
sub Main<br>
<br>
{<br>
local ($srchdir) = $_[0];<br>
local (*files);<br>
opendir(SRCHDIR, "$srchdir") ¦¦ die "Can't open $srchdir";<br>
@files = grep(!/^\.\.?$/,readdir(SRCHDIR));<br>
while ($file_name = pop(@files))<br>
{<br>
($name,$ext) = split(/\./,$file_name);<br>
if ((-e "$srchdir/${file_name}") && (($ext eq "html") ¦¦ ($ext eq "HTML") ¦¦ ($ext eq "htm") ¦¦ ($ext eq "HTM")))<br>
{<br>
&CopyFile("$srchdir","${file_name}");<br>
}<br>
elsif (-d "${srchdir}/${file_name}")<br>
{<br>
&Main("$srchdir/${file_name}");<br>
}<br>
}<br>
close (SRCHDIR);<br>
}<br>
