php date()
Tutorial by: Sazzad Hossain
php date() - the PHP date() function formats a timestamp to a more readable date and time. The first parameter in the date() function specifies how to format the date/time. It uses letters to represent date and time formats. Some of these formats include:
Important Full Date and Time:
* r: Displays the full date, time and timezone offset. It is equivalent to manually entering date("D, d M Y H:i:s O")
Time:
* a: am or pm depending on the time
* A: AM or PM depending on the time
* g: Hour without leading zeroes. Values are 1 through 12.
* G: Hour in 24-hour format without leading zeroes. Values are 0 through 23.
* h: Hour with leading zeroes. Values 01 through 12.
* H: Hour in 24-hour format with leading zeroes. Values 00 through 23.
* i: Minute with leading zeroes. Values 00 through 59.
* s: Seconds with leading zeroes. Values 00 through 59.
Day:
* d: Day of the month with leading zeroes. Values are 01 through 31.
* j: Day of the month without leading zeroes. Values 1 through 31
* D: Day of the week abbreviations. Sun through Sat
* l: Day of the week. Values Sunday through Saturday
* w: Day of the week without leading zeroes. Values 0 through 6.
* z: Day of the year without leading zeroes. Values 0 through 365.
Month:
* m: Month number with leading zeroes. Values 01 through 12
* n: Month number without leading zeroes. Values 1 through 12
* M: Abbreviation for the month. Values Jan through Dec
* F: Normal month representation. Values January through December.
* t: The number of days in the month. Values 28 through 31.
Year:
* L: 1 if it's a leap year and 0 if it isn't.
* Y: A four digit year format
* y: A two digit year format. Values 00 through 99.
Other Formatting:
* U: The number of seconds since the Unix Epoch (January 1, 1970)
* O: This represents the Timezone offset, which is the difference from Greenwich Meridian Time (GMT). 100 = 1 hour, -600 = -6 hours

So basically all you have to do is call the date() function. You can accomplish this by simply using the following call-out after your <body tag or wherever you wish for it to appear. Please note the function echo. "PHP function echo is a means of outputting text to the web browser. Throughout your PHP career you will be using the echo function more than any other" (tizag)
<?php
echo date("ITEMHERE");
?>Replace ITEMHERE with the designated character from the list above. If you want to display a normal date format, enter the following
<?php
echo date("M. d, Y");
?>Output for this code is the following: Dec. 15, 2007
Comments
Tutorial by: Sazzad Hossain
Lets go back to HTML. In HTML there is only one type of commenting. Unlike HTML, php has two types; single line comment and a multi-line comment.
A single line comments tells the reader (server) to ignore everything to the right side of the comment on the line. To complete the single line, we use the two forward slash ( // ) at the very beginning of the comment. All content to the right of the two forward slashes will be counted as comments.
Comment example 1
<?php echo "Welcome WDF Users!"; // YOUR comment can be posted here echo "<br />Forum with the coolest free templates and services!"; // no one will know what you put here // you can even comment a function echo "comment a function"; ?>
This will output the following
Welcome WDF Users!
Forum with the coolest free templates and services!
A multi-line comment can be used to comment out large chunks of code or text (similarly to the HTML comment). The multi-line comment in php begins with a /* (forward-slash followed by asterisk) and ends with */ (asterisk and forward-slash).
Comment example 2
<?php /* This comment cannot be viewed by any normal guests, you can use this sort of comment to remove or not use a certain line of code from your source such as include "home.php" */ echo "Welcome WDF Users!"; ?>
This will output the following
Welcome WDF Users!
