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: On Thu, 10 Jan 2002 05:54:49 -0500, Gerard Samuel wrote: >Thats my biggest concern now, performance with whatever alternatives >that can be dreamed up... >Anyway, its 6 in the morning, time for sleep.

Thats my biggest concern now, performance with whatever alternatives that can be dreamed up... Anyway, its 6 in the morning, time for sleep.

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
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
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:

[PHP] array_shift and php 4.0.4
Hey all. Im putting together a script and Im having a couple people
test it out.
Here is a bit of code...
$c = explode ('/', dirname($PHP_SELF));
array_shift($c);
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.
Fatal error: Call to unsupported or undefined function array_shift() in
file.php on line 15
Where/Is there anything wrong with 4.0.4??
