Description

Category: Deprecated Functionality
Call-time pass-by-reference has been deprecated in more recent versions of PHP. Instead of specifying the & prefix in the function call, use it in the function declaration instead.

Example

Deprecated function increment($n)
{
    $n++;
}

$foo = 5;
increment(&$foo);
Correct function increment(&$n)
{
    $n++;
}

$foo = 5;
increment($foo);
