Well for the first time, it seemed that producing HTML Help output
from DSSSL generated output filtered through some formatting regepxs
are better then
a) Writing a new DSSSL customization or
b) Writing a new XSL customization
because
a) Starting always from XML sources seems too much pain to me,
as we have many HTML formats out here. To generate every
format from XML, we need to pay with our time for too much
repetitive work
b) XSL is currently not supported enough in phpdoc
c) It takes much more time to generate output from XML than
output from HTML using my custom regexps (related to prev
point). As we already have DSSSL generated HTML, why not
reuse it?
d) I have no profession to do the customizations for the
cute things we decided to include in the HTML Help Edition.
e) Some of these customizations are even not possible with
DSSSL/XSL, for example the color coding of examples.
Some of the customizations would be a pain to implement,
like "path to this page", as it is more easier to implement
in PHP...
Well, I know, that using some heavily customized XSL style sheets
would be the best method for interoperability, wide range of
tools available, and general point of view. But after considering
the points above, I decided to use regexps in PHP to filter DSSSL
generated HTML code.
With each and every new "filter" I add to my regexps, I see that
this is not the best way in the long run, but it's still fast, and
it works. I have just sent a sample to [EMAIL PROTECTED]
with the current filtered DSSSL HTML files. They look quite
professional (with some CSS related exceptions).
There are some points where my concept fails:
a) in the future, DSSSL will go out, and it would mean a need
for a complete overhaul of my filter code (it is based
heavily on DSSSL created HTML constructs)
b) while the code is well commented, it is still hard to
modify to reflect filtering needs, as complex pregs
are not that easy to understand, and pregs to filter
complex structures are not that easy to implement
I would not like to ask anybody to help me figure out how
to implement XSL code producing equivalent output to our
filters output, as
a) we have no final desired output
b) the thing to do are quite complex, and time consuming
I attached a sample created by our interface designer,
Holger Eggert, presenting how manual page structures
look like (this is not a correct date manual page,
as it contains all the stuff we considered to be formatted,
like tables, warnings, and so on).
I cannot feel enough power in myself to make any XSL
customizations to produce HTML code as seen in
date_lo.html currently.
The official mailing list for discussion about designs,
programs, CSS, JS and other related issues is

Title: date
date
Format a local time/date. (PHP 3, PHP 4 >= 4.0.0)
Usage: string date (string format, int [timestamp])
Returns a string formatted according to the given format string using the given integer timestamp or the current local time if no timestamp is given.
Note: The valid range of a timestamp is typically
from Fri, 13 Dec 1901 20:45:54 GMT to Tue, 19 Jan 2038 03:14:07 GMT. (These
are the dates that correspond to the minimum and maximum values for a 32-bit
signed integer.)
To generate a timestamp from a string representation of the date, you may be
able to use strtotime(). Additionally, some databases have functions to convert
their date formats into timestamps (such as MySQL's UNIX_TIMESTAMP function).
The following characters are recognized in the format string:
- a - "am" or "pm"
- A - "AM" or "PM"
- B - Swatch Internet time
- d - day of the month, 2 digits with leading zeros; i.e. "01" to "31"
- D - day of the week, textual, 3 letters; i.e. "Fri"
- F - month, textual, long; i.e. "January"
- g - hour, 12-hour format without leading zeros; i.e. "1" to "12"
- G - hour, 24-hour format without leading zeros; i.e. "0" to "23"
- h - hour, 12-hour format; i.e. "01" to "12"
- H - hour, 24-hour format; i.e. "00" to "23"
- i - minutes; i.e. "00" to "59"
- I (capital i) - "1" if Daylight Savings Time, "0" otherwise.
- j - day of the month without leading zeros; i.e. "1" to "31"
- l (lowercase 'L') - day of the week, textual, long; i.e. "Friday"
- L - boolean for whether it is a leap year; i.e. "0" or "1"
- m - month; i.e. "01" to "12"
- M - month, textual, 3 letters; i.e. "Jan"
- n - month without leading zeros; i.e. "1" to "12"
- O - Difference to Greenwich time in hours; i.e. "+0200"
- r - RFC 822 formatted date; i.e. "Thu, 21 Dec 2000 16:01:07 +0200" (added in PHP 4.0.4)
- s - seconds; i.e. "00" to "59"
- S - English ordinal suffix, textual, 2 characters; i.e. "th", "nd"
- t - number of days in the given month; i.e. "28" to "31"
- T - Timezone setting of this machine; i.e. "MDT"
- U - seconds since the epoch
- w - day of the week, numeric, i.e. "0" (Sunday) to "6" (Saturday)
- Y - year, 4 digits; i.e. "1999"
- y - year, 2 digits; i.e. "99"
- z - day of the year; i.e. "0" to "365"
- Z - timezone offset in seconds (i.e. "-43200" to "43200"). The offset for timezones west of UTC is always negative, and for those east of UTC is always positive.
Unrecognized characters in the format string will be printed as-is. The "Z" format will always return "0" when using gmdate().
This is a normal H1-header.
And deep within some usual text we have an » external link, which will open a new browser window.
Warning: This function is EXPERIMENTAL. The behaviour of this function, the name of this function, and anything else documented about this function may change in a future release of PHP without notice. Be warned and use this function at your own risk.
Here we list some of the most important command line options with detailed explanations.
Table B-1. Command line options
| Option | Description |
|---|---|
| -q | Suppress HTTP headers output. Normally PHP prints out HTTP headers for the calling program (ie. webserver) to hand on to the browser. When writing command line applications these headers are useless. |
| -s | Display the color highlighted source of the file given with its name. This is the same as if you were printing out the source using the highlight_file() function in a PHP script. |
| -f | Parse the file given, and search for syntactical and fatal errors. This option implies -q. Use for debugging purposes. |
| -v | By calling PHP with this option, you can ask it to print out its version number, ie: 4.0.6. |
Example 1.date() example
echo date ("l dS of F Y h:i:s A");
echo "July 1, 2000 is on a " . date ("l", mktime(0,0,0,7,1,2000));
You can prevent a recognized character in the format string from being expanded by escaping it with a preceding backslash. If the character with a backslash is already a special sequence, you may need to also escape the backslash.
Example 2. Escaping characters in date()
echo date("l \\t\h\e jS"); // prints something like 'Saturday the 8th'
It is possible to use date() and mktime() together to find dates in the future or the past.
Example 3. date() and mktime() example
$tomorrow = mktime (0,0,0,date("m") ,date("d")+1,date("Y"));
$lastmonth = mktime (0,0,0,date("m")-1,date("d"), date("Y"));
$nextyear = mktime (0,0,0,date("m"), date("d"), date("Y")+1);
Note: This can be more reliable than simply adding or substracting the number of seconds in a day or month to a timestamp because of daylight savings time.
Some examples of date() formatting. Note that you should escape any other characters, as any which currently have a special meaning will produce undesirable results, and other characters may be assigned meaning in future PHP versions. When escaping, bu sure to use single quotes to prevent characters like \n from become newlines.
Example 4. date() Formatting
/* Today is March 10th, 2001, 5:16:18 pm */
$today = date("F j, Y, g:i a"); // March 10, 2001, 5:16 pm
$today = date("m.d.y"); // 03.10.01
$today = date("j, m, Y"); // 10, 3, 2001
$today = date("Ymd"); // 20010310
$today = date('h-i-s, j-m-y, it is w Day z '); // 05-16-17, 10-03-01, 1631 1618 6 Fripm01
$today = date('\i\t \i\s \t\h\e jS \d\a\y.'); // It is the 10th day.
$today = date("D M j G:i:s T Y"); // Sat Mar 10 15:16:08 MST 2001
$today = date('H:m:s \m \i\s\ \m\o\n\t\h'); // 17:03:17 m is month
$today = date("H:i:s"); // 17:16:17
To format dates in other languages, you should use the setlocale() and strftime() functions.

getlastmod(), gmdate(), mktime(),
strftime() and time().

[EMAIL PROTECTED] (15-Dec-2001 03:22)
Be carefull when adding or substracting months in date:
$lastmonth = mktime
(0,0,0,date("m")-1,date("d"),date("Y"));
If the day is the 30th or 31st it will not work.

change the format of date
//e.g. timestamp = 2002-01-04 13:34:26
//format = Y-m-d H:i:s
list($date, $time) = explode(" ", $timestamp);
//modify "-" if your input is separated by other char
//modify the sequence of $yr, $mon and $day if your input is in different
sequence
list($yr, $mon, $day) = explode ("-", $date);
//modify ":" if your input is separated by other char
//modify the sequence of $hr, $min and $sec if your input is in different
sequence
list($hr, $min, $sec) = explode(":", $time);
$newtime = mktime($hr, $min, $sec, $mon, $day, $yr);
//then you can change the format of date as you like
$newdate = date("d-m-Y H:i:s", $newtime);
//newdate = 04-01-2002 13:34:26
