    for($y=0; $y<=$height; $y++){
        $int = hexdec($data[$i++]);

推荐答案

imagejpeg( $image, $filename );

会将图像保存到$filename.因此基本上可以做到

will save the image to $filename. So essentially could do

imagejpeg( $image, $filename );
imagedestroy( $image );
readfile( $filename );

不只是打电话

imagejpeg( $image );
