PHP GD庫，將兩個圖像並排放入一個並排

Question

我想拍攝兩張圖像並將它們並排（並非重疊）。我想要做的一個例子就像是前後圖片（兩張圖片的寬度都不相同）。任何示例代碼如何完成PHP GD圖像庫將不勝感激。謝謝！

<?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); 

?>
