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 protected]($argv[1])) throw new Exception($error);<br /> else echo 'true';<br />} catch (Exception $e) {<br /> echo 'false';<br />}<br />?><br />
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!!

感觉 getimagesize 更好些(不需 GD 支持)

说真的没这样用过!分数这么高!顶一下!

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

其实我就是来接分的,多谢楼主

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?

You should care about DependencyInjection(DI) because it makes your code clearer and easier to maintain. 1) DI makes it more modular by decoupling classes, 2) improves the convenience of testing and code flexibility, 3) Use DI containers to manage complex dependencies, but pay attention to performance impact and circular dependencies, 4) The best practice is to rely on abstract interfaces to achieve loose coupling.

Select DependencyInjection (DI) for large applications, ServiceLocator is suitable for small projects or prototypes. 1) DI improves the testability and modularity of the code through constructor injection. 2) ServiceLocator obtains services through center registration, which is convenient but may lead to an increase in code coupling.
