我正在制作图像裁剪的代码，并使用上面的代码保存裁剪后的图像。我可以使用imagecreatefromjpeg裁剪和保存jpg文件，也可以将函数更改为imagecreatefrompng。我可以裁剪png文件。请帮助我使用此代码一次验证或保存多种类型的图像谢谢
$src = $_POST['photo_url'];
$what = getimagesize($src);
switch(strtolower($what['mime']))
{
case 'image/png':
$img_r = imagecreatefrompng($src);
$source_image = imagecreatefrompng($src);
$type = '.png';
break;
case 'image/jpeg':
$img_r = imagecreatefromjpeg($src);
$source_image = imagecreatefromjpeg($src);
error_log("jpg");
$type = '.jpeg';
break;
case 'image/gif':
$img_r = imagecreatefromgif($src);
$source_image = imagecreatefromgif($src);
$type = '.gif';
break;
default: die('image type not supported');
}
感谢这是有效的任何类型的图像所需的代码
