Strict standards Variable Passing warning on PHP

Strict standards Variable Passing warning on PHP

If you get warning regarding Variable Passing on functions and "strict standards" on PHP, it probably means you have called a function by reference and passed it a value instead of a variable. For instance:

function showPet(&Tpet)
{
echo $pet;
}

showPet("cat")

will give the warning.

$p = "cat";

showPet($p);

will not.
