<?php
$src_path = 'ha.jpg';
//创建源图的实例
$src = imagecreatefromstring(file_get_contents($src_path));
//裁剪开区域左上角的点的坐标
$x = 100;
$y = 12;
//裁剪区域的宽和高
$width = 200;
$height = 200;
//最终保存成图片的宽和高,和源要等比例,否则会变形
$final_width = 100;
$final_height = round($final_width * $height / $width);
//将裁剪区域复制到新图片上,并根据源和目标的宽高进行缩放或者拉升
$new_image = imagecreatetruecolor($final_width, $final_height);
imagecopyresampled($new_image, $src, 0, 0, $x, $y, $final_width, $final_height, $width, $height);
//输出图片
header('Content-Type: image/jpeg');
imagejpeg($new_image);
imagedestroy($src);
imagedestroy($new_image);
