Here you are a simple function to rotate a variable according to an array of possible values. You
can make a strict comparison (===).
<?php
function rotateValue($string, $values, $strict = TRUE)
{
if (!empty($string) AND is_array($values))
{
$valuesCount = count($values);
for ($i = 0; $i < $valuesCount; $i++)
{
if ($strict ? ($string === $values[$i]) : ($string == $values[$i]))
{
return $values[($i + 1) % $valuesCount];
}
}
}
return FALSE;
}
?>
For example:
- rotateValue("A", array("A", "B", "C")) will return
"B"
- rotateValue("C", array("A", "B", "C")) will return
"A"
