PHP Image Upload Resizer
Need a good way to resize your uploaded image? While keeping the height/width ratio?
Why would you need to do this? Well, like most of you, I did not need to keep full sized images that I upload on page, and needed a good way to create thumbnails, and resize the originals down to a more manageable, more web friendly size.
This will do the trick… no words of caution, no instructions, just code… use it how you like 🙂
<?php
function ResizeImage($inputFile, $filepath, $ext, $maxWidth, $maxHeight){
/* Get some details about the image */
$srcDetails = getimagesize($inputFile);
switch ($srcDetails[2]) {
case 1: //GIF
$source_image = imagecreatefromgif($inputFile);
break;
case 2: //JPEG
$source_image = imagecreatefromjpeg($inputFile);
break;
case 3: //PNG
$source_image = imagecreatefrompng($inputFile);
break;
case 6: //WBMP
$source_image = imagecreatefromwbmp($inputFile);
break;
default:
break;
}
/* Original Dimensions */
$width = imagesx($source_image);
$height = imagesy($source_image);
// Target and original image ratio
$target_ratio = $maxWidth / $maxHeight;
$original_ratio = $width / $height;
/* find the "desired height" of this thumbnail, relative to the desired width, and vice-versa */
if(($maxWidth <= $width) || $maxHeight <= $height){
if($target_ratio == $original_ratio){
// ratio's are equal, no need to calculate
$desired_height = $maxHeight;
$desired_width = $maxWidth;
}elseif($target_ratio > $original_ratio){
// need to get the proper width
$desired_height = $maxHeight;
$desired_width = $width * ($maxHeight / $height);
}elseif($target_ratio < $original_ratio){
// need to get the proper height
$desired_height = $height * ($maxWidth / $width);
$desired_width = $maxWidth;
}
}else{
$desired_height = $maxHeight;
$desired_width = $maxWidth;
}
$virtual_image = imagecreatetruecolor($desired_width, $desired_height);
imagecopyresized($virtual_image, $source_image, 0, 0, 0, 0, $desired_width, $desired_height, $width, $height);
/* create the physical thumbnail image to its destination */
switch ($srcDetails[2]) {
case 1: //GIF
imagegif($virtual_image, $filepath);
imagedestroy($virtual_image);
break;
case 2: //JPEG
imagejpeg($virtual_image, $filepath, 100);
imagedestroy($virtual_image);

case 3: //PNG

imagewbmp($virtual_image, $filepath);
imagedestroy($virtual_image);

Enjoy, and as always…
Happy Coding!
