Date time does not match time zone problem

First, Reason

Starting with php5.1.0,PHP. INI has date.timezone this option and is turned off by default
That is, the time displayed (whatever PHP command is used) is Greenwich Mean Time
And our Time (Beijing time) The difference is exactly 8 hours.

Ii. Solutions

method One : Add the following code before you get the time:
Date_default_timezone_set (PRC);

method Two : Change the php.ini inside the formulation, the specific operation is as follows:
Open php.ini Find Date.timezone Remove the preceding semicolon = after plus xxx (PRC), restart the HTTP service (such as Apache2 or IIS, etc.)
such as: DATE.TIMEZONE=PRC

For XXX, the values available in mainland China are: asia/chongqing, Asia/shanghai, Asia/urumqi, PRC (Chongqing, Shanghai, Urumqi, PRC)
Taiwan available: Asia/macao, Asia/hong_kong, Asia/taipei (Macau, Hong Kong, Taipei, respectively)
and Singapore: Asia/singapore
Others: Etc/gmt-8, Singapore, Hongkong

method Three : Echodate ("y-m-d h:i:s", Time () +8*60*60);

Example:

[PHP] view plain copy

2. <?php
4. Show date and time of day
6. Date_default_timezone_set (PRC);
8. $date =date ("y-m-d h:i:s");
10. echo $date. " <br> ";
14. Show yesterday's date and time
16. $yesterday =date ("y-m-d h:i:s", Time () -24*60*60);
18. $y 1=date ("y-m-d h:i:s", Mktime () -24*60*60);
20. echo $yesterday. " <br> ";
22. echo $y 1. " <br><br> ";
26. $z =date ("z") +1; Week is: 0123456
28. echo "Today is the first of 2010". $z. " Day <br><br> ";
32. $z =date ("z") +5; Week: 0123456 January 1 Friday 4+1=5
34. $w =ceil ($z/7);
36. echo "<br> today is the first of 2010". $w. " Zhou <br><br> ";
40. $time =time ();
42. Echo $time;
46. ?>
