Merge two images in php

by

The best approach for this situation may be to create a new image in memory with the combined dimensions you desire, then copy or resample the existing images to the new image, and then save the new image to disk.

For example:

function merge($filename_x, $filename_y, $filename_result) {

 // Get dimensions for specified images

 list($width_x, $height_x) = getimagesize($filename_x);
 list($width_y, $height_y) = getimagesize($filename_y);

 // Create new image with desired dimensions

 $image = imagecreatetruecolor($width_x + $width_y, $height_x);

 // Load images and then copy to destination image

 $image_x = imagecreatefromjpeg($filename_x);
 $image_y = imagecreatefromgif($filename_y);

 imagecopy($image, $image_x, 0, 0, 0, 0, $width_x, $height_x);
 imagecopy($image, $image_y, $width_x, 0, 0, 0, $width_y, $height_y);

 // Save the resulting image to disk (as JPEG)

 imagejpeg($image, $filename_result);

 // Clean up

 imagedestroy($image);
 imagedestroy($image_x);
 imagedestroy($image_y);

}

Example:

merge('images/myimg.jpg', 'images/second.gif', 'images/merged.jpg');
