File handling question

[Anon]

I have a basic directory listing script, what Id like to do though is display the filenames in the directory without showing the extension of each file. Does anyone know how this might be done?

This is the script Im using:

<?php

$default_dir = "./images";
if(!($dp = opendir($default_dir))) die("Cannot open $default_dir.");
while($file = readdir($dp))
if($file != '.' && $file != '..') echo "$file<br>";

closedir($dp);

?>

Does this solve your problem?

<?php

$default_dir = "./images";
if(!($dp = opendir($default_dir))) die("Cannot open $default_dir.");
while($file = readdir($dp))
if($file != '.' && $file != '..') {
explode(".",$file);

echo $file[0]."<br>";

closedir($dp);

?>

Good luck.

Sorry, I made an error in my haste...

explode(".",$file);

Should be

$file = explode(".",$file);

Oops.

Assuming by "extension" you mean everything before the last dot, use strrchr(). If you mean everything before the first dot, use strchr(). Use one of those to find the dot, and then user substr() to get everything before it.

Uhh no that didnt work and ive no idea how to use strchr() & substr() in that way, the way I was trying didnt work anyway.

Does anyone else have any idea?

Uhh never mind, managed to solve it myself (again)

Not exactly important right now anyway...
