Remove filename extension

[redgunner]

Hey This is my code

<?
$imglist='';
$img_folder = "images/users/";
  mt_srand((double)microtime()*1000);
$imgs = dir($img_folder);
while ($file = $imgs->read()) {
   if (eregi("gif", $file) || eregi("jpg", $file) || eregi("png", $file))
     $imglist .= "$file ";
} closedir($imgs->handle);
$imglist = explode(" ", $imglist);
$no = sizeof($imglist)-2;
$random = mt_rand(0, $no);
$image = $imglist[$random];
echo '<img src="'.$img_folder.$image.'" border=0 width=166 height=134><br />';
print $image
?>

 

 

as you can see on the lastline is $image and it displays ImageName.jpg however I want it to display only ImageName and not the extension.

function RemoveExtension($strName) 
{ 
     $ext = strrchr($strName, '.'); 

     if($ext !== false) 
     { 
         $strName = substr($strName, 0, -strlen($ext)); 
     } 
     return $strName; 
}

 

usage:

echo RemoveExtension($filename);

So like...

 

<?
$imglist='';
$img_folder = "images/users/";
  mt_srand((double)microtime()*1000);
$imgs = dir($img_folder);
while ($file = $imgs->read()) {
   if (eregi("gif", $file) || eregi("jpg", $file) || eregi("png", $file))
     $imglist .= "$file ";
} closedir($imgs->handle);
$imglist = explode(" ", $imglist);
$no = sizeof($imglist)-2;
$random = mt_rand(0, $no);
$image = $imglist[$random];
echo '<img src="'.$img_folder.$image.'" border=0 width=166 height=134><br />';
echo RemoveExtension($image);

function RemoveExtension($strName)
{
     $ext = strrchr($strName, '.');

     if($ext !== false)
     {
         $strName = substr($strName, 0, -strlen($ext));
     }
     return $strName;
}

?>

<?php

function RemoveExtension($img) {
    $pos = strrpos($img, '.');

    if($pos) $str = substr($img, 0, $pos);
      else $str = $img;
  return $str;
}

?>

There is also the basename function, however it requires you to know the extension. But doing what the others did you could just substitute it in where substr is, however substr should be fine.
