如何使用PHP批量上传时创建缩略图并将其保存到具有相同名称的子文件夹

Question

我有一个php脚本，该脚本在目录中搜索以获取所有文件夹和图像，并获取其数据并将其保存到m mysql db。但是现在我想从抓取的图像创建php图像缩略图，这也为我找到了正确的解决方案，但是我不确定如何以正确的方式保护图像。在包含图像的主文件夹中的Thumbs文件夹中。这是我的代码有什么想法吗？

<?php


include_once("../assets/inc/colors.inc.php");

/* The image from which the palette will be generated */
$image_to_read = "img/footer.jpg";


/* Make sure that this number is a perfect square - 9,16,25,36 etc;
   this will enable you to create a square palette grid.

   The following for example will create a 5x5 grid.
 */

$colors_to_show = 6;

$pal = new GetMostCommonColors();
$pal->image = $image_to_read;
$colors = $pal->Get_Color();
$colors_key = array_keys($colors);


$inc = sqrt($colors_to_show);
 $imgcolors = "";
for ($i = 0; $i < $colors_to_show; $i += $inc) {


    for($j=0;$j<$inc;$j++) {
        $imgcolors .= "".$colors_key[$i + $j].",";
    }

}
$imgcolors .= "";
//echo $imgcolors;
