PHP Conversion of Unix Timestamp

1. Convert Unix timestamp to something like "2012-05-12 11:09:15" Format:

date('Y-m-d H:i:s',$time); //$time的值即Unix时间戳，可能是你从数据库里取出来的或者...

2. Convert the time in "2012-05-12" format into a timestamp:

strtotime("2012-05-12"); //返回值为int型

3. Print the timestamp of the current time:

echo(time());

Advanced

In fact, the date function provided by PHP is very easy to use. For example, if you want to convert the Unix timestamp into the date format you want, such as "May 25, 2012":

date(‘Y年m月d日’,$time);

You can see that the date function is only interested in "Y", "m", and "d". As for the special characters you inserted in the middle, she doesn't pay much attention.

■Year – “Y” represents the four-digit year. 2012

■Year – “y” represents a two-digit year. 12

■Month – “F” means the full spelling of the English month. January will be displayed as "january"

■Month - "M" represents the first 3 characters of the English month. January will be displayed as the abbreviation of january "jan"

■month - "m" represents the numeric month. January is displayed as "01" and December is "12"

■Day – "j" represents a numeric date. If the date is a single digit, "0" will not be added to the high digit, for example: "9", "12"

■Day - "d" represents a numeric date. If the date is a single digit, the high digit will be filled with "0", for example: "09", "12"

Add "0", for example: "3", "12"

■ Hour - "G" time in twenty-four-hour format, if it is a single-digit high digit, "0" will not be added, for example: " 3”, “18”

■Hour – “h” is the twelve-hour time. If it is a single-digit high digit, “0” will be added, for example: “03”, “12”

■Hour - "H" twenty-four-hour time, if it is a single-digit high digit, "0" will be added, for example: "03", "18"

■Minute - "i" minute , for example: "09", "60"

■Seconds - "s" seconds, for example: "06", "60"

Finally, please note that if it is a twelve-hour clock Time format output, need to indicate morning and afternoon

For example: echo date('g:i:s a');

The output result is: 5:56:57 am

echo date(‘h:i:s A’);

The output result is: 05:56:57 AM

“a”上午=am、下午=pm;”A”上午=AM、下午=PM
