合併幾個圖像與imagecopyresized

Question

我想將幾個圖像合併成一個。下面列出了這個數組。

$ products_settings - 數組：數組$products_settings是（在這種情況下whateverfile3.jpg）

<?php 
header('Content-Type: image/jpeg'); 

foreach($products_settings as &$ps) { 

    //Original-product/image-file 
    $filename = $ps['product_file']; 
    list($source_width, $source_height) = getimagesize($filename); 
    $source_image = imagecreatefromjpeg($filename); 

    //Destination image (as large as outfit-area-canvas) 
    $dest_image = imagecreatetruecolor(intval($canvas_settings['width_canvas']), intval($canvas_settings['height_canvas'])); 
    $dest_width = intval($ps['product_width']); 
    $dest_height = intval($ps['product_height']); 
    $dest_x = intval($ps['product_left']); 
    $dest_y = intval($ps['product_top']); 

    //Resize source-image to new width and height and then copy from source to destination    
    imagecopyresized($dest_image, $source_image, $dest_x, $dest_y, 0, 0, $dest_width, $dest_height, $source_width, $source_height); 

    imagejpeg($dest_image, 'dummy.jpg'); 

} 
?> 

只有最後一個圖像：

(
[0] => Array 
    (   
     [product_left] => 368 
     [product_top] => 317 
     [product_width] => 67.0 
     [product_height] => 85.0 
     [product_file] => /whateverfile1.jpg 
    ) 

[1] => Array 
    (
     [product_left] => 569 
     [product_top] => 459 
     [product_width] => 67.0 
     [product_height] => 85.0 
     [product_file] => /whateverfile2.jpg 
    ) 

[2] => Array 
    (
     [product_left] => 710 
     [product_top] => 359 
     [product_width] => 67.0 
     [product_height] => 85.0 
     [product_file] => /whateverfile3.jpg 
    ) 

) 

我已經試過這合併成dummy.jpg文件，但我想將所有三種產品合併到dummy.jpg文件中。我怎麼能做到這一點？請給我一些指點！

您不斷在每個循環上重新創建目標圖像......在循環開始之前將其放置。

然後在所有循環完成後輸出圖像。
