Remove the elements, then use sort().

I believe that array_values() will do the trick.

I've given a simplified example. The actual target array is
multi-dimensional. Sort() won't work in a case like that, as far as I
know. Moreover, I don't want the array sorted based on the element
values.

Ahh, I see - you wanted me to guess at the actual circumstances of the
case instead of provide an answer to the example you posted. My bad.

Your questioni sn't entirely clear but there's lot of chatter about
multidimensional arrays on the array_values() page that might provide
a solution.

how about creating two arrays, one empty one.
pop the elements
you want out of the first array and push them to the second. skip
the push on the elements you don't want in the second array?
Just a thought.

strtotime() (http://php.net/strtotime) and date() (http://php.net/date).
There's even a DATE_ISO8601 constant for the correct date format.

You'd use the strtotime function to convert the IETF format to a timestamp,
then then date function to convert that timestamp to ISO8601.
Something like date(DATE_ISO8601, strtotime('IETF format string')).

exec() tends to allocate to much resources and Runkit_Sandbox is what
I'm trying to get away from =)
The Runkit_Sandbox requires that the server is configured to use it and
my intended solution will run on almost any server without any spcial
needs. (exec is also restricted from many hosting server which makes it
a poor choise.)
My little SandBox will run on almost any server and doesn't require any
special configuration. Sure, it will suck on resources but it will work
as an alternative =)

Hello All,
Im writing a script that creates a temp file which it then encrypts and
sends out in an email.
This works 100% on servers that don't have safe mode, but this server with
safe mode doesn't understand it's all the same user.
Error:
Mon Mar 14 21:10:11 2011] [error] [client 14.18.8.43] PHP Warning: fopen()
[<a href='function.fopen'>function.fopen</a>]: SAFE MODE Restriction in

Greetings,
I'm moving some scripts from an older server (SuSE who-knows-what,
running PHP 5.2.5) to a newer one (Ubuntu 10.10, running PHP 5.3.2).
For the most part there haven't been any problems, or they've been
things that I was able to fix easily. This one's got me stumped. I
have the following line in a script:
$this->bc = ($this->network | (~$this->netmask)) & 4294967295;
$this->network and $this->netmask should both be of type long, and I
should wind up with another long. I didn't write the original method,
and I can't remember what "bc" stands for at the moment, but it's part
of a tool for working out first and last IP address, netmask, and a
few other things from a subnet definition.
On the old system, it works fine. On the new system, I get the following error:
"PHP Fatal error: Unsupported operand types in
/var/www/test/common_subnet.inc on line 39"
I've done a little searching without any luck: if anyone can give me
a quick answer, or at least point me to something that will explain
what's going on, I'd appreciate it.
Thanks,
Alex McKenzie

Have you checked the types being operated on? I'm wondering if somehow one
of the object properties you're operating on has changed has changed in
terms of type.
I'd try var_dumping each of the properties ($this->network and
$this->netmask) the line above just to make sure they didn't somehow get
switched to a type that bitwise operators complain about (array, Object.)

I want to be able to match if a string is contained within the string I am
evaluating.
I know that if ( $name == "xxjacksonxx"); based on the below would be true.
But I want to be able to say if "jackson" is contained within $name that
it's a match.
I tried the below without success..
Not getting the operand properly..
<?
$name = "xxjacksonxx";
if ( preg_match($name, "jackson")) {
print "true";
} else {
print "false";
}

if(strpos($name, 'jackson') !== false) {
true
}
You can use stripos for case-insentive matching.
Using regex functions when you don't need the power is overkill and slower.
Your call to preg_match wasn't working because you need your search term first,
and it needs proper delimiters.
