我想通过两个标准在这个表中找到重复的记录.首先是SKU,第二个是UPC.在这种情况下,重复记录是[1,2,3,4]和[5,6].行[1,2]是重复的,因为sku数字是匹配的.行[1,3,4]是重复的,因为UPC编号是匹配的.第一个重复组应如下所示:

我使用以下方法来调整图像大小:
private function newDim($maxHeight, $maxWidth, $height, $width) {
if(($width / $height) >= ($maxWidth / $maxHeight)){
$nw = $maxWidth;
$nh = $height * ($maxWidth / $width);
$nx = round(abs($maxHeight - $nh) / 2);
$ny = 0 ;
}else {
// by height
$nw = $width*($maxHeight/$height);
$nh = $maxHeight;
$nx = 0;
$ny = round(abs($maxWidth - $nw) / 2); ;
}
return array($nw,$nh,$nx,$ny);
