Definition: As it's name implies, elseif () works similar to if () and else () statements. However, using elseif () gives you more than two possible outcomes. Unlike else () which executes in all cases the if () is false... elseif () only executes if the statement is true.
Also Known As: Else If
Examples:
<?php
if ($x > $y)
{
echo "x is larger than y";
}
elseif ($x == $y)
{
echo "x is equal to y";
}
else
{
echo "x is smaller than y";
}
?>
