I want to pass $bugpos to the function and
have it manipulate it im already using the 'return'
Is there any way to pass a 'handle' to the variable
so it gets manipulated by the function and passed back?

Code:

<?php
 $myvar2 = '222';
 $worked = dosomethingwiththisvar($myvar2);
 echo $myvar2;
 // it says 222 , not 223 
?>

<?php

function dosomethingwiththisvar($myvar){
 $myvar++;
 return true;
}

?>

[perkiset]

<?php

$count = 100;
for ($i=0; $i<10; $i++)
{

doSomething($count);

echo "$count\n";
}

function doSomething(&$myVar)
{

$myVar++;
}

?>

It's the ampersand in the function declaration before the variable that you want passed by reference that does it. By default all variables (except arrays and objects) are passed by value.

thats to pass the reference.
but the other way obviously:

<?php
 $myvar2 = '222';
$myvar2 = dosomethingwiththisvar($myvar2);
 echo $myvar2; //spits out 223
?>

<?php
function dosomethingwiththisvar($myvar){
 $myvar++;
 return $myvar;
}
?>
