如何在文件夹中使用文件名作为PHP库的标题时排除文件扩展名？

Question

Considering my working code for creating a gallery from a folder (g-images/) and using the file names for captions, how do I go about to exclude from such captions other file extensions other than *.jpg (i.e. *.png, *.gif)?

at the moment the only extension that gets removed is *.jpg. if it's any other extension it's kept as part of the caption for the image...

HELP, total newbie here :-)

<?php
   $imglist = array();
   $img_folder = "g-images/";

   //use the directory class
   $imgs = dir($img_folder);

   //read all files from the  directory, checks if are images and adds them to a list 
   while ($file = $imgs->read()) {
   if (eregi("gif", $file) || eregi("jpg", $file) || eregi("png", $file)){
   $imglist[] = $file;
   } 
 }
 closedir($imgs->handle);

 //display image
 foreach($imglist as $image) {
 echo '<li><a href="'.$img_folder.$image.'" target="zoomed"><img src="timthumb.php?src='.$img_folder.$image.'&a=r&h=260" />';
 echo '<p>'.str_replace('.jpg', ' ', str_replace('name', 'Name', $image)).'</p></a></li>';
 }
?>

Answer 1

echo '<p>'.str_replace(array('.jpg', '.png', '.gif'), ' ', str_replace('name', 'Name', $image)).'</p></a></li>';
