[RESOLVED] Question about dealing with files...

[michelfeldman]

How do I make a script read the files in a directory, and do something to each one of the files?

for example:

read first file -> use imagemagick on it
read next file -> use imagemagick on it

etc... to all the files in the directory.

Thanks,

Michel

Don't forget glob().

$files = glob("directory/*");
foreach($files as $file)
{
  // do something to $file
}

I made the following script to make thumbnails with imagemagick:

<?php

define("IMAGES_DIR",opendir("images"));        // The directory where the images are
define("THUMBS_DIR",opendir("thumbs"));		 // The directory where to put the thumbnails

define("IMAGEMAGICKPATH","/usr/local/bin");		 // ImageMagick's directory on the server
define("THUMB_WIDTH",100); 					 // the wanted thumb width 
define("THUMB_HEIGHT",100);					 // the wanted thumb height

while (false !== ($filename = readdir(IMAGES_DIR))) {
	if ($filename!="." && $filename!="..") {
		// Get the image height and width
		$size = getimagesize($filename);   	// size[0] = width, size[1] = height

	// Wide Image
	if($size[0] > $size[1]) {  
		exec("convert $filename -gravity center -crop $size[1]x$size[1]+0+0 +repage -thumbnail THUMB_WIDTHxTHUMB_HEIGHT THUMBS_DIR"."/"."$filename");
	}  

	// Tall Image
	else {
		exec("convert $filename -gravity center -crop $size[0]x$size[0]+0+0 +repage -thumbnail THUMB_WIDTHxTHUMB_HEIGHT THUMBS_DIR"."/"."$filename");
	}
}
}

?>

And I get errors:
