Hi! this is really a spooky situation! A. problem with a class only happening in one site (other implementations use same class and always worked fine). B. It only happens the first time I hit the site. C. press F5, or re-enter address, and the problem is gone. D. restarting browser, causes the problem again. E. problem is: The 2nd time I call a method on a certain object, neither the method parameters, neither the global vars are acessible, only the pre-declared class members are there. Remember, i have made a call to this method in the same script exexcutation, some 20 lines before. F. Even more spooky, some vars tend to echo values (wrong values) but var_dump shows NULL for the same var, right from the next line of code!!! G. Check below example: output 1, 3 and 4 show vardump of function parameters NULL ouput 2 shows that local var $_query (the function's parameter $_query) receives the return value of the previous function foofunction() call output 3 shows that variable is in fact NULL output 5 shows that local var is not accessible output 6 shows that global var is accessible output 7 and 8 shows class members ok output 9 and 10 shows assigning local vars impossible!!!! H. Don't belive me? TEST IT: http://66.220.28.17/zero/index.php Looks like assignment of variables is totally messed up (currupt?) The script is like dead: I also tried unseting the global instance of $mydbclass and recreating it, but I get NULL if I vardump the new instance!!! Please help me on this one! //:: CODE EXTRACT FOLLOWS //:: test function function foofunction($_bla) { return "YOUR BLAH: ".$_bla; } $fooglobal= "fooglobal"; // function call $mydbclass->query("select id from user"); //class definition class mydbclass { var $version = 1.0 function mydbclass() { $this->connect(); } // more class methods ... function query($_query = "foo", $_fooparam = "bar") { global $fooglobal; global $queryix; $queryix++; $foolocal = "foolocal"; $this->foonewmember = "foonewmember"; echo "($queryix) _query="; var_dump($_query);echo BR; //:: 1 outputs: (2) _query=NULL if (!($this->tmp = mysql_query($_query))) { ; $this->tmp2 = $this->bla("select id from zero_user"); echo "_query echo="; echo($_query); //::2 outputs: _query echo=YOUR BLAH: bla bla echo "_query dump="; var_dump($_query); //::3 ouputs: _query dump=NULL echo "_fooparam="; var_dump($_fooparam); //::4 ouputs: fooparam=NULL echo "globalfoo="; var_dump($fooglobal); //::5 ouputs: fooglobal=fooglobal echo "foolocal="; var_dump($foolocal); //::6 ouputs: foolocal=NULL echo "foonewmember="; var_dump($this->foonewmember); //::7 ouputs: foonewmember=string(12) "foonewmember" echo "foooldmember="; var_dump($this->foooldmember); //::8 ouputs: foooldmember=string(9) "foooldmember" echo "result1="; var_dump($this->result1); //::9 ouputs: result1=bool(false) echo "result2="; var_dump($this->result2); //::10 ouputs: result2=NULL } // more class methods ... } // end of class __________________ Thanks, Andr?

This is definitely a valid bug, as I am seeing almost exactly what Andre is describing. The current problem I am seeing is with this function below: ************* function meta($page, $time=2){ print "$page $time "; printf('<META http-equiv="refresh" content="%d; URL=%s">', $page, $time); printf('http-equiv="refresh" content="%d; URL=%s">\n', $page, $time); # Just to have the meta tag print to the screen } meta('/example/page.html'); **************** # Note: I have plugged this into a page by itself and it works as expected. I will try to post a page that does display this problem, but currently, there is a lot of stuff to strip out before I can post it. This would print a simple meta refresh for a page, when it works. When it doesn't work, what I'm seeing: '1 1 http-equiv="refresh" content="0; URL=">' and the refresh shows up as <META http-equiv="refresh" content="0; URL="> Which makes no sense at all. The time right after the 'content' section shows up as a '0', which I guess means the variable is really null. If I change the printf statements to print strings for both, then the variable after the content print nothing, as in 'content="; URL=">' As described before, by Andre, refreshing the page in the browser fixes the problem, unless you close the browser, or delete the session file in /tmp worked for me also. As I said, I will try to provide some useable code to backup these wild accusations : ) but currently there are so many requires, and openldap queries that it might be awhile. thanks
