Re: [PHP] array_shift and php 4.0.4
Strange, are you sure it's 4.0.4 ??
The manual for array_shift() says it's supported from 4.0.0 .
Maybe try the alias array_pop() ?
otherwise there'll be other ways to strip the first part of the directory,
for example using regexp, try something like:
?
ereg(^[^/]/(.*)$, dirname($PHP_SELF), $regs);
$c = explode(/, $regs[1]);
?

It runs fine on my box, php 4.0.6, apache 1.3.22.
On a box with php 4.0.4pl1, apache 1.3.20 it spits an error.

Where/Is there anything wrong with 4.0.4??

Re: [PHP] array_shift and php 4.0.4
Yeah its 4.0.4. I figure it strange also since array_shift was there
since 4.0.0.
array_pop(), isn't that for the last element. I want to take out the
first element, thus array_shift.
Ill try the regexp and see how it goes...
Ill report back
Thanks

Re: [PHP] array_shift and php 4.0.4
You are right, I should've known (used it before) .. Ofcourse you could do an array_reverse() before and after, don't know about the performance impact of that however. bvr. array_pop() and array_shift are *different* :) array_pop() takes an element off the END of the array. array_shift() takes an element off the START of the array. -- PHP General Mailing List (http://www.php.net/) To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED] To contact the list administrators, e-mail: [EMAIL PROTECTED]

Re: [PHP] array_shift and php 4.0.4
Actually, my 'don't know' was more like 'does anyone know?' .
But I figured I could find that out for myself.
Wrote a small script that creates an array (numeric indexed range) of
10,000 elements.
Then it calls array_reverse() on it 100 times.
This took a little more than 3 secs. on a P3, which is relatively slow IMO.
Ofcourse two calls won't really hurt if you have a fast server.
A larger array of 100,000 elements took more then 30 secs. (hit the timelimit) ..
So the speed is clearly affected by the size of the array, *maybe* even by the size of
the elements ..
Here's the code I used to test:
?php
set_time_limit(3600);
$arr = range(1, 1);
start_clock();
for ($i = 0; $i 100; $i++)
{
array_reverse($arr);
}
echo(get_clock() . \n);
// timer functions
function start_clock()
{
global $start;
$start = microtime();
}
function get_clock()
{
global $start;
$stop = microtime();
$start = split( , $start);
$stop = split( , $stop);
$start = (float)$start[0] + $start[1];
$stop = (float)$stop[0] + $stop[1];
$time = $stop - $start;
$htime = (int)($time / 3600);
$time -= ($htime * 3600);
$mtime = (int)($time / 60);
$time -= ($mtime * 60);
$stime = ((int)($time * 100) / 100);
$stime = ereg_replace(\., s, $stime);
if ($htime)
{
$clock = $htime . H;
}
if ($mtime)
{
$clock .= $mtime . m;
}
return $clock . $stime . h;
}
?

bvr.
array_pop() and array_shift are *different* :)
array_pop() takes an element off the END of the array.
array_shift() takes an element off the START of the array.
