Upload Script

I am upgrading an upload script I made a week ago. But this time I wanna make it so you can only upload cetain file types. How would I go about doing this?

RE: Upload Script

When they upload the file, have a look at the file extension to see if it is allowed or not. I'm guessing it would be something like this, but I'm no good with patterns:

php Code:

Original - php Code
<?php if (ereg("$[gif\|bmp\|jpg\|jepg\|png]", $_FILES['varname']['name'])) { do stuff here } ?>

 
<?php
if (ereg("$[gif|bmp|jpg|jepg|png]", $_FILES['varname']['name']))
 {
  do stuff here
 }
?>

Someone please correct that as necessary...

RE: Upload Script

php Code:

Original - php Code
<?php $arr=array('jpg', 'png', 'gif', '...'); $file=$_FILES['file']['filename']; $dot=strrpos($file, '.'); $ext=substr($file, $dot+1); $ext=strtolower($ext); if (in_array($ext, $arr)) { //do stuff here } ?>

 
<?php
    
    $arr=array('jpg', 'png', 'gif', '...');
    
    $file=$_FILES['file']['filename'];
    $dot=strrpos($file, '.');
    $ext=substr($file, $dot+1);
    $ext=strtolower($ext);
    
    if (in_array($ext, $arr)) {
        //do stuff here
    }
    
?>
