Resize images in to another directory - php

Question

I have the following in place for all my images in /images/500x500/. I need to resize the images to 250x250 and have them go into the /images/250x250/ with the same filename.
It doesn't create the new image in the new directory, rather it replaces the large in the same directory?
<?php
$files = glob("*.{png,jpg,jpeg}", GLOB_BRACE);
foreach ($files as $file)
{
// get the image size
$imagesize = getimagesize($file);
$width_orig = $imagesize[0];
$height_orig = $imagesize[1];
$dst_w = 250;
if($width_orig != $dst_w)
{
$dst_h_multiplier = $dst_w / $width_orig;
$dst_h = $dst_h_multiplier * $height_orig;
$dst = imagecreatetruecolor($dst_w, $dst_h);
$image = imagecreatefromjpeg($file);
imagecopyresampled($dst, $image, 0, 0, 0, 0, $dst_w, $dst_h ,$width_orig, $height_orig);
imagejpeg($dst, $outputFile, 100);
$outputFile =
realpath(
pathinfo($file, PATHINFO_DIRNAME)
. '/../250x250/'
) . pathinfo($file, PATHINFO_BASENAME);
}
}
?>

$outputFile =
realpath(
pathinfo($file, PATHINFO_DIRNAME)
. '/../'
) . pathinfo($file, PATHINFO_BASENAME);
First, you need the path, which you can get with realpath(), along with pathinfo(). Then, just append a .. and the file name.

Also, you might not need realpath(). I haven't tested.
