RE: [PHP] unix timestamp

[Mike richardson]

The attached class is a date utility that I created a long time ago.  

It parses out SQL dates, does differences, and specific to your needs,
you can use dateAdjust() to move a unix timestamp by a number of
seconds, minutes, hours, days, months, quarters, years or centuries.

You should be able to either employ this class, or simply look through
the code to find the answers to most of your date woes.  The only thing
this class doesn't do, is account for leap years, when working with
quantities that span multiple months. (never got around to this yet,
suppose I will need to before 2004!)

Attached is also a short readme to explain what the functions are and
what they do (the code itself is also well commented).

Best wishes!

Subject: [PHP] unix timestamp


Hi everybody,

I am trying to create a unix timestamp which dates back a certain amount
of days. Lets say I would like to have a unix timestamp from 7 days ago.

what I tryed is just to subtract values since this are counted s since
the start of the unix epoche, but this does not work in cases like the
switch of months. Has anybody an idea how to do that?

Thanx, Andy

RE: [PHP] formatting a filename

[Mike richardson]

Ereg() would be an excellent choice.

To move a step further, although it is a little more complex to become
familiar with, the perl regular expressions are considerably faster and
more efficient for anything with an expression, and str_replace() is
faster yet, if replacing a simple string.

Thus, it would probably be best to use:

$clean_term = str_replace(  , _, $term);  // replace spaces with _
$clean_term = preg_replace(@[^a-zA-Z0-9_.]@, , $term); // remove any
non-alphanumeric chars

There is an excellent article somewhere that gives some benchmark times
for the various methods... Anyone know where this is?  I can't seem to
find it anymore.

However, I remember the basic concept:  on a given string, preg_replace
ran about 1 second, ereg_replace ran about 4 seconds, and str_replace
ran about .2 seconds.

See these docs for info about syntax:
http://www.php.net/manual/en/function.preg-replace.php
http://www.php.net/manual/en/function.str-replace.php
http://www.php.net/manual/en/function.ereg-replace.php

RE: [PHP] How do I get milliseconds?

[Mike richardson]

If you are looking for milliseconds on the current time, see the
examples on microtime():
http://www.php.net/manual/en/function.microtime.php

Here is a summary of how to get milliseconds:

list($usec, $sec) = explode( ,microtime()); 
$milliseconds = (((float)$usec/1000) + (float)$sec);

I haven't tested this out, but it looks right.

Using the following code,

date(His)

I get the hours, minutes and seconds.  Is there a way to extend this so
that I get the milliseconds too?

Thanks,
Don

How do you alternate colors of the rows in a table inside a while
statement when dealing with the output of data from a DB. I am sure it's
something simple but I keep getting into some really long math thing...

[PHP] Set Variable to Multiple Lines

[Mike richardson]

I've been searching for this old php feature (perhaps it was
deprecated), and can't get the right keywords to look it up.

There was a way, similar to the perl method shown below, to set multiple
lines of data equal to a variable.

(in perl)
$variable = __SOME_HEADER_HERE__

Put whatever is desired here, including $variables.

Just end it with this:

__SOME_HEADER_HERE__;


Anyone know what this is for PHP?
