buffer nbsp output

趁着人少……
散分啰!!!!!!!!!!
50楼或者明年1月2日结贴

循例发个没用的东西,不然管理员转到非技术区就浪费分了

检查jpeg是否有错误,需要GD

<br /><?php<br />try<br />{<br />    if ([email&#160;protected]($argv[1])) throw new Exception($error);<br />    else echo 'true';<br />} catch (Exception $e) {<br />    echo 'false';<br />}<br />?><br />
Copy after login

这个比python的PIL还好用,PIL有些查不出,也没有py3.3可用的pygd,令我很郁闷
建议结合jpeg的文件头和文件尾可以省点CPU资源



今年好倒霉,被骗了很多钱,希望来年好些……

祝大家新年好!!

新年快乐

响应lz  让此贴成为技术贴  问个问题
ob_get_status() returns status information on either the top level output buffer or all active output buffer levels if full_status is set to TRUE. 

ob_get_status
可以返回一个数组  表示这个buffer的状态
比如
(
    [level] => 1
    [type] => 1
    [status] => 0
    [name] => default output handler
    [del] => 1
)
里面有个level  这个是表示什么的
有什么用呀.
万能的LZ

imagecreatefromjpeg 虽然是GD库,不过好像安装完PHP后,是默认打开的。
和 getimagesize 相比,哪个更占内存和CPU?

用size不能查出图片中间交错的jpg,就是那些打开图片会看到中间有横线的那种
看需求吧,如果单纯检查上传下载有没有断,用头尾字节基本能确认95%了
我是写来查自己硬盘上的坏图……
