date( )
---------------------------------
string date ( string date_format [, int timestamp] )
Users like to have their dates in a variety of formats, so PHP lets you convert timestamps into different types of strings using the date( ) function.
You can send two parameters to date( ), with the second one being optional, as with strtotime( ). Parameter one is a special string containing formatting codes for how you want the timestamp converted, and parameter two is the timestamp you want to convert. If you do not supply the second parameter, PHP assumes you want to convert the current time.
Parameter one is tricky: it is a string of letters from a predefined list of 31 possibles. You can use other characters in the string, and these are copied directly into the formatted date. If you are trying to put words into the date format that you do not want to be converted into their date equivalent, you need to escape them with a backslash, \. To make things even more confusing, if your escaped letter is an existing escape sequence, then you need to escape it again!
The complete list of date format characters is shown in table. Be careful, as they are case-sensitive!

This first example of date( ) is very basic and prints out the current time in 24-hour clock format:
print date("H:i");
It's possible to mix the output of date( ) with a text string to get a natural-looking statement, like this:
print "The day yesterday was " . date("l", time( ) - 86400);
Note that on very specific occasions (particularly when daylight savings time kicks in), the above script will be incorrect. If you need absolute precision, either check for DST or subtract a whole day using mktime( ).
This next example outputs the date in the format of 31st of August 2005. Notice that we have the word of in the date format, and it has been passed through to the output instead of being converted. The reason for this is that lowercase O and lowercase F do not have any formatting purpose in the date function (although this may be changed in the future), so they are just copied straight into output:
print date("jS of F Y");
In the next example, our date( ) function is embedded between two other strings, which makes for particularly neat output:
print "My birthday is on a " . date("l", strtotime("22 Dec 2004")) . " this year.";

Dear nyphp:
I am very new to php programming and need some assistance relating to displaying to dates using php.
I wrote a script that involves menu pull-downs for dates that should appear into a form as the end result.
I have the form into a table and all of the other td's appear, except the dates. I get a 0000/00/000 for the date fields.
I did a goggle for displaying dates in php, but the results are showing me what i have already done.
Could some one please direct me or give a sample code on how I can get the dates to appear in the proper context (not 0000/00/00). Thank you in advance
