PHP GD library, turn 2 images into 1 side by side
I want to take two images and turn them into one side by side (no overlapping). An example of what I would like to do is something like a before and after image (both images are the same height with a different width). Any code example on how to do this with the PHP GD image library is greatly appreciated. Thank!

<?php
$img1_path = 'images_1.png';
$img2_path = 'images_2.png';
list($img1_width, $img1_height) = getimagesize($img1_path);
list($img2_width, $img2_height) = getimagesize($img2_path);
$merged_width = $img1_width + $img2_width;
//get highest
$merged_height = $img1_height > $img2_height ? $img1_height : $img2_height;
$merged_image = imagecreatetruecolor($merged_width, $merged_height);
imagealphablending($merged_image, false);
imagesavealpha($merged_image, true);
$img1 = imagecreatefrompng($img1_path);
$img2 = imagecreatefrompng($img2_path);
imagecopy($merged_image, $img1, 0, 0, 0, 0, $img1_width, $img1_height);
//place at right side of $img1
imagecopy($merged_image, $img2, $img1_width, 0, 0, 0, $img2_width, $img2_height);
//save file or output to broswer
$SAVE_AS_FILE = TRUE;
if( $SAVE_AS_FILE ){
$save_path = "your target path";
imagepng($merged_image,$save_path);
}else{
header('Content-Type: image/png');
imagepng($merged_image);
}
//release memory
imagedestroy($merged_image);
?>
try it
