  echo "a equals 5";
    echo "...";
elseif ($a == 6):
    echo "a equals 6";
    echo "!!!";
else:
    echo "a is neither 5 nor 6";
endif;
?>

Note:

Mixing the two syntaxes within the same control block is not supported.

Warning

Any output (including spaces) between switch and the first case will result in a syntax error. For example, this is invalid:

<?php switch ($foo): ?>
    <?php case 1: ?>
    ...
<?php endswitch ?>

But this is valid, because the newline character after switch is considered to be part of the closing tag ?>, so there cannot be any output between switch and case:

<?php switch ($foo): ?>
<?php case 1: ?>
    ...
<?php endswitch ?>
