php中本地时区设置
输出当前时间:

<?php $time   = date('Y-m-d H:i:s');
echo $time;


咦?怎么是 2009-02-26 06:52:58。 本机(上海)时间明明是:2009-02-26 14:52:58
我的时间整整提前了进入未来8个小时:) 大家已经猜出来了,东八区,是时区问题,php如何知道时区呢?通过更改php.ini中的设置:
[Date]
; Defines the default timezone used by the date functions
date.timezone = Asia/Shanghai

重新启动服务器,重新运行代码你就会看到时间输出一致了

php5中php.ini默认是GMT时间,北京是+8时区,
不建议在php.ini中修改时区设置可通过php脚本来设置,若您有自己完全管理权的服务器当然也可以在php.ini中修改默认时区设置。如果没有权限改php.ini,
可以用函数ini_set(),date_default_timezone_set通过以下方法来设置
<?php date_default_timezone_set('Asia/Shanghai');//'Asia/Shanghai'   亚洲/上海
date_default_timezone_set('Asia/Chongqing');//其中Asia/Chongqing'为“亚洲/重庆”
date_default_timezone_set('PRC');//其中PRC为“中华人民共和国”
ini_set('date.timezone','Etc/GMT-8');
ini_set('date.timezone','PRC');
ini_set('date.timezone','Asia/Shanghai');
ini_set('date.timezone','Asia/Chongqing');

通过echo date_default_timezone_get();来查看设置。

In PHP, iterating through session data can be achieved through the following steps: 1. Start the session using session_start(). 2. Iterate through foreach loop through all key-value pairs in the $_SESSION array. 3. When processing complex data structures, use is_array() or is_object() functions and use print_r() to output detailed information. 4. When optimizing traversal, paging can be used to avoid processing large amounts of data at one time. This will help you manage and use PHP session data more efficiently in your actual project.

mPDF

mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
