How to avoid call-time pass-by-reference deprecated error in PHP?

Question

I\'m trying to reduce the warnings that are sent to my apache server log.

One warning is:

Call-time pass-by-reference has bee

Answer 1

like noted above in a previous answer, the issue is at CALL time, not definition time.. so you could define a function as:

function foo(&$var1,$var2,$var3=null){
    // procesing here
}

then call as:

$return = foo($invar1,$invar2);

your first invar is passed by reference, second one is not.

the error appears when you try to call like so:

$return = foo(&$invar1,$invar2);
