PHP Log输出格式化日期

Question

I want to write some logs to a file via PHP but when I want to output the date I don't find anything "standard" to simply write a complete date like : Wed Aug 13 12:38:02 2014 (and with the timezone, etc).

I found a lot of examples with the date() function but you have to pass a lot of args (and I'm not sure if it's standard). By standard I mean something POSIX compliant (or something similar), understood by any program which want to parse this log file.

It is up to you how to format the date. Actually, the date function is pretty easy to handle.

echo date("Y-m-d") // will output: 2014-08-13
echo date("Y-m-d H:i") // will output: 2014-08-13 16:25

the date function accepts a 2nd parameter, which is by default time() (so the actual timestamp).

You can specifiy the output by just adding the / changing the parameters in the brackets. For example:

echo date("d.m.Y") // will output 13.08.2014
