Splitting a string

This numer has dynamic lenght, witch is the root of my problems.

$number = 123456789

should print as following:
var1: 12345 (and it is this lengt witch varies)
var2: 67
var3: 89.

I've been using substr with negative numbers to fetch the last two vars.
thereafter explode to get the first number.
Ok I understand the code and can use it, but it feels wrong.
Does anyone have any idea on suitable functions for such a task, both more
size (as in code) and speed effective. It is not a mission critical, but
moreover a opinion of what things should look like.
I've been looking into string/explode functions on php.net without getting
past my current code.

Assuming var1 and var2 only ever use the last four numbers (untested):

$length = strlen($number); // get string length
$var1 = substr($number,0,$length-4); // get number until only 4 numbers are
left
$var2 = substr($number,$length-4,2); // get 3rd and 4th last numbers.
$var3 = substr($number,$length-2,2); // get last two numbers.

How can I insert header() info directly into the ob_start stream?

I am compressing a css file with php before it is outputted to the
browser,
The below DOES work, but I have to insert the php header() info
DIRECTLY into the css file.
Otherwise, mystyle.css is interpreted as text/html instead of text/css.
If possible, I would like to keep css and php code separated.

Is this possible, or is there an alternate way?
many thanks


compress-css.php:

<?php

/* header info is not working anywhere I put it :( */
/*
header('content-type:text/css');*/
header("Expires: ".gmdate("D, d M Y H:i:s", (time()+900)) . " GMT");
*/

ob_start("compress");

function compress($buffer) {
// remove comments
$buffer = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '',
$buffer);

// remove tabs, spaces, newlines, etc.
$buffer = str_replace(array("\r\n", "\r", "\n", "\t", ' ', '
', ' '), '', $buffer);
return $buffer;
}
?>



mystyle.css:
/* css file is run thru compress-css.php before outputed to the
browser */

<?php
header('content-type:text/css');
header("Expires: ".gmdate("D, d M Y H:i:s", (time()+900)) . " GMT");
?>
#menu {font: normal 1.88em/1em Georgia, Times New Roman, Times,
serif; font-variant: all-caps; margin:0 .1em;}
....rest of css goes here


..htaccess file:
AddHandler application/x-httpd-php .css
php_value auto_prepend_file /path/to/compress-css.php

You can also do this with a regular expression:

$iNumber = '123456789';
$sPattern = '/(\d+)(\d{2})(\d{2})$/';
preg_match($sPattern, $iNumber, $aMatches);

Then $aMatches contains:

Array
(
[0] => 123456789
[1] => 12345
[2] => 67
[3] => 89
)

The regexp pattern /(\d+)(\d{2})(\d{2})$/ means:

(one or more digits) (two digits) (two digits) [end of string]

No need to work out the length of the string.

$var1 = substr($number, 0, -4);
$var2 = substr($number, -4, 2);
$var3 = substr($number, -2);

Thanks. Its a much more sophisticated code with three values in one array,
rather than my solution with 2 vars from the substr and one array with one
value from explode. Never used preg_match like this before. =)

Why do I suddenly feel stupid ;D magnificent!

Easier than the preg_match solution, but not as compact.

Oh this was good.
I added a while loop to insert extra strings "0" in front of the number to add
if the string is less than 5 chars short.

I forgot to mentinon that the string actually could be shorter (just found
out) and the code didn't work with fewer than 5 char strings.
But now is rocks.

Thanks again.

sprintf is your friend here, no need to use a loop.

sprintf('%05d', '1234');
