Problems with globals

[michelleqw]

Dear PHP users,

We make in the beginning of our code a variable constant $cnt. In function doing() we increment this variable but when we echo after de call function the variable the variable it is still zero!

code:

<?php
global $cnt ;
$cnt = 0 ;
doing() ;
echo "second $cnt<br>" ;


function doing()
{
$cnt++ ;
echo "first: $cnt<br>" ;
}
?>

Can someone tell us what we do wrong?


Nice regards,

Michelle.

you need to move the global $cnt into the doing function

--BB

Like BB101 posted, declare the variable 'global' inside the function.
something like

<?php
    $cnt = 0    ;
    doing() ;
    echo "second $cnt<br>"    ;


    function doing()
    {
	global $cnt ;
        $cnt++  ;
        echo "first: $cnt<br>"    ;
    }
?>
