php variables disappear???

valter_ego_barb

Hello,

I'm having this really huge problem: my php variables just get reseted somewhere along the execution of the script.

I've done lots of debugging and could not find the point where the variables go away. In my system (winXP, php5, Apache) all works fine, but at the real server (linux, php4-cgi, apache) it simply does not work.

I've tracked the variables all the way up to the output, and they seem to disappear just before.

I'm using a template engine that parses template files by including them in the script,and them using extract() to assign variables to values and returning the buffered output. The server has register_globals on, could this be the problem?

Can someone point me to a way to solve this?

Thanx,
Ricardo

please post your code.

register_globals on

means that one does not have to specify a"collection" or super globals array to get $var from as long as $var exists in any one of the many super global arrays. For example, the following code:

print $var

would print a value if any one of the numerous superglobals have a key: "var". Like $POST['var'], $GET['var'], $_COOKIE['var'], etc. If they all had a "var" key I do not know the ensuing precedence. This is among the many reasons (security concerns included) that using

register_globals on

is considered a bad idea. I would certainly use a superglobals array instead if you are currently relying on functionality from register_globals on.

hello, thanx for help.

let's say that I have a class called Builder that builds web pages from a configuration file. The code is something like this:

	class Builder {

	function Builder($smap) {

		$this->_doLog = false;

		$this->_dbg = Debugger::getDebugger(DBG_STR);
		set_error_handler($this->_dbg->getDebugHandler());
		register_shutdown_function(array(& $this, '_endScript'));

		// ...
	}

	// ...

	function printDoc($err = false) {

		if($err !== false) {
			// print err doc and exit
		} else {
			print $this->doc();	// a generated document
			$this->_doLog = true;
			exit;
		}
	}

	// ...

	function _endScript() {

		if($this->_dbg->hasErrors()) {
			$this->_dbg->flushBuffer();	
		}
		if($this->_logger !== null && $this->_doLog) {
			$this->_logger->log();
		}
	}
}

This class is the basic class for the whole site.

If I call any page, by the time the function exits and calls the endScript function the page access never gets logged because the doLog variable is false even if no errors occurred and the printDoc() function set it to true just before calling the end of the script.

Now it get's event more strange, because if I comment the register_shutdown() function, and call the endScript() after printing the document the doLog variable has the propper value.

The thing is that on every class weird stuff like this is happening, forms don't get any post or get values, assigned variables default to initial settings, and on and on and on...in all documents, regardless of the way I exit the script!!!

I don't really if explained my self very well, but thanks for your support,
