PHP has deprecated call-time pass-by referenc, which means that you should not do something like
this
<?php
function addFive($Number) {
$Number = $Number + 5;
}
$Number = 2;
addFive(&$Number);
echo $Number;
?>
Even though the above code will work, it will throw a warning about call-time pass-by ref. being
deprecated.
There are several ways to get around it:
1. Modify the function definition of
<?php
function addFive($Number) {
$Number = $Number + 5;
}
?>
to
<?php
function addFive(&$Number) {
$Number = $Number + 5;
}
?>
Notice the & (ampersand) before $Number.
PHP.net doesn't allow very long posts so read the rest here for one more method
