Can anyone show me where to add the strtolower(____HERE____) to my code below?
This is a image upload / thumbnail script that I found, and made a few additions to.

Problem is I want the files to be renamed on my server, and in the dB all lowercase.
No matter what I try, it still comes back like: 120_4353.JPG

<?
	} else  if (isset($_GET['subpage']) && $_GET['subpage'] == 'upload') {
	
	// Set $url To Equal The Filename For Later Use
		$url = $_FILES['imagefile']['name'];
		
	if ($_FILES['imagefile']['type'] == "image/jpg" || $_FILES['imagefile']['type'] == "image/jpeg" || $_FILES['imagefile']['type'] == "image/pjpeg") { 

	// Get The File Extention (.jpg, .gif or .php)
		$file_ext = strrchr($_FILES['imagefile']['name'], '.');

	// Move Image From Temporary Location To Permanent Location
		$copy = copy($_FILES['imagefile']['tmp_name'], "$idir" . strtolower($_FILES['imagefile']['name']));

	// If The Script Was Able To Copy The Image To It's Permanent Location 
			if ($copy) {

			// Successfull Upload
				$url = strtolower($url);
				$simg = imagecreatefromjpeg("$idir" . $url);

	// Make A New Temporary Image To Create The Thumbnail From 
			
			// Current Image Width
				$currwidth = imagesx($simg);

			// Current Image Height 
				$currheight = imagesy($simg);

			// If Height Is Greater Than Width 
				if ($currheight > $currwidth) {

				// Length Ratio For Width
					$zoom = $twidth / $currheight;

				// Height Is Equal To Max Height 
					$newheight = $theight;

				// Creates The New Width
		         $newwidth = $currwidth * $zoom;

			} else {
			
	// Otherwise, Assume Width Is Greater Than Height (Will Produce Same Result If Width Is Equal To Height) 

				// Length Ratio For Height 
					$zoom = $twidth / $currwidth;

				// Width Is Equal To Max Width 
					$newwidth = $twidth;

				// Creates The New Height
					$newheight = $currheight * $zoom;
			} 

	// Make New Image For Thumbnail
			$dimg = imagecreate($newwidth, $newheight);

		// Create New Color Pallete
			imagetruecolortopalette($simg, false, 256);
			$palsize = ImageColorsTotal($simg); 

		// Counting Colors In The Image
			for ($i = 0; $i < $palsize; $i++) {
			
			// Number Of Colors Used
				$colors = ImageColorsForIndex($simg, $i);

			// Tell The Server What Colors This Image Will Use
				ImageColorAllocate($dimg, $colors['red'], $colors['green'], $colors['blue']);
      } 

		// Copy Resized Image To The New Image (So We Can Save It)
			imagecopyresized($dimg, $simg, 0, 0, 0, 0, $newwidth, $newheight, $currwidth, $currheight); 
	    
		// Saving The Image
			imagejpeg($dimg, "$tdir" . $url);

	      imagedestroy($simg);   // Destroying The Temporary Image 
	      imagedestroy($dimg);   // Destroying The Other Temporary Image
      
		// Resize successful      
			echo '<table><tr><td><img src="http://www.carcityofdanbury.com/inventory/'.$idir.strtolower($url).'" width="365" height="274" /></td></tr><tr><td class="upTxt"><img src="../images/Common/Icons/bulletOn.gif"> Image successfully added.</td></tr><tr><td class="upTxt"><img src="../images/Common/Icons/bulletOn.gif"> Thumbnail successfully created.</td></tr></table><div class="close"><a href="javascript:parent.window.focus(); top.window.close();" onclick="window.opener.location.href = \'http://www.login.carcityofdanbury.com/passed/edit.php?category=001&stock='.$stock.'\'">Close Window</a></div>'; 
			if ($copy) {$mysql_query = "UPDATE Inventory SET $field = '$url' WHERE stock= '$stock'"; mysql_query($mysql_query) or die(mysql_error());}
		} else { 
		// If Upload Failed 
			echo '<font color="#FF0000">ERROR: Unable to upload image.</font>';
		} 
	} else { 
	// Not .jpg or .JPG file
		echo '<font color="#FF0000">ERROR: Wrong filetype (has to be a .jpg or .jpeg. Yours is '; 
		echo $file_ext;   // Show The Invalid File's Extention 
		echo '.</font>'; 
	} 
}

 ?>

if you want the file extension to be lower case then do the following:

PHP Code:

$file_ext = strtolower($file_ext); 


Hope that helps. By the way using the PHP tag rather than the CODE tag makes it easier to read your php, also some of your lines are extremely long. Breaking them up into smaller lines improves readibility.

And please learn to use imagemagick's convert and mogrify command line utilities to resize pictures. If somebody uploads a dozen of hi-res pictures simultaneously your script would simply crash due to memory limits. And if you then try to fix the problem by increasing php memory_limit value you can easily get your server hung.

The only one that would EVER use this script would be the site admin... Which is me, so I dont need to worry about that.

Well, once you will try to create a script for users to upload images.
