图片上传后如何查看尺寸
如果它与我想要的尺寸不符,请将其删除吗?
因此,经过深入研究,我发现 PHP 无法处理维度。我遵循的解决方案是:
- 将文件上传到服务器
- 使用新字符串并检查
- 如果有则删除或继续上传
宽度和高度不匹配
这是我的代码。有人可以告诉我如何检查当前文件的尺寸以及如何删除不匹配的文件夹和文件吗?
# create our temp dir
mkdir("./uploads/temp/".$user."/".$mx."/".$hash."/", 0777, true);
# upload dir settup
$uploaddir='./uploads/temp/'.$user.'/'.$mx.'/'.$hash.'/';
$file=$uploaddir . basename($_FILES['file']['name']);
# upload the file first
if (move_uploaded_file($_FILES['file']['tmp_name'], $file)) {
# ok so check the height and width
# if it is not the width and height assigned delete image and folder
if (image height= and width =){
unlink($file);
rmdir($uploaddir);
$result=0;
} else {
# image matches height and width message ok
$result=1;
}
} else {
# error uploading
$result=$errormsg;
}
mkdir("./uploads/temp/".$user."/".$mx."/".$hash."/", 0777, true);
# upload dir settup
$uploaddir='./uploads/temp/'.$user.'/'.$mx.'/'.$hash.'/';
$file=$uploaddir . basename($_FILES['file']['name']);
# upload the file first
if (move_uploaded_file($_FILES['file']['tmp_name'], $file)) {
# ok so check the height and width
# if it is not the width and height assigned delete image and folder
$size = getimagesize($files);
$maxWidth = 500;
$maxHeight = 500;
if ($size[0] > $maxWidth || $size[1] > $maxHeight)
{
unlink($file);
rmdir("./uploads/temp/".$user."/".$mx."/".$hash."/");
rmdir("./uploads/temp/".$user."/".$mx."/");
rmdir("./uploads/temp/".$user."/");
}
else
$result=1;
end if
} else {
# error uploading
$result=$errormsg;
}
