Our webserver scripts make heavy use of the phplib.
with php4.3.0rc1 I will get the error

Fatal error: Cannot redeclare gc() in /usr/lib/php/phplib/ on line 461

thats because phplib defines a function named gc().

with the php4.3.pre1 and earlier versions this problem has not been apeared - last but not least with the documentation I have not found a hint about a gc() function within php itself.

seems that this is an enhancement of php - because the bug is really in phplib. sorry.

Has anybody got a solution for this problem. The same thing is happening to some of our websites. Is there some setting in php.ini file that can be set to get around this problem.

This one also just hit me upgrading from 4.2.3 to 4.3.0 on 
Gentoo Linux.  Since I cannot seem to find a solution 
online, I will try and rename the PHPLIB functions.

SURELY someone knows how to fix this annoying error?  It was first reported over 2 months ago and there are no postings on this problem report showing a resolution.  Well?

I found it to be an old line in my php.ini:

auto_prepend = /usr/local/apache/php/prepend.php3

Update your php.ini and you'll see it goes away again.

Edwin, bitten by this problem too :-)

The problem does not appear to be that php defines a gc() function that phplib is clobbering, but that phplib's file actually tries to define gc() twice.

I was able to eliminate the error message and problems by commenting out the first gc() declaration in, as follows:

        // Garbage collection
        // Destroy all session data older than this
        /* function gc() {
                $this->that->ac_gc($this->gc_time, $this->name);
        } */

Would be interested in anyone's opinion as to whether this was terribly foolish, or an accurate fix to the problem.

I have the same problem still, because of this I have to run php 4.2.2 and this made me sad! I've tried to run php 4.3.4 and I get the "Cannot redeclare gc() in"-problem.
Is there anyone that will fix this problem?
