elseif, as its name suggests, is a combination
of if and else. Like
else, it extends an if
statement to execute a different statement in case the original
if expression evaluates to
FALSE. However, unlike
else, it will execute that alternative
expression only if the elseif conditional
expression evaluates to TRUE. For example, the
following code would display a is bigger than
b, a equal to b
or a is smaller than b:
<?php if ($a > $b) { echo "a is bigger than b"; } elseif ($a == $b) { echo "a is equal to b"; } else { echo "a is smaller than b"; } ?>
There may be several elseifs within the same
if statement. The first
elseif expression (if any) that evaluates to
TRUE would be executed. In PHP, you can also
write 'else if' (in two words) and the behavior would be identical
to the one of 'elseif' (in a single word). The syntactic meaning
is slightly different (if you're familiar with C, this is the same
behavior) but the bottom line is that both would result in exactly
the same behavior.
The elseif statement is only executed if the
preceding if expression and any preceding
elseif expressions evaluated to
FALSE, and the current
elseif expression evaluated to
TRUE.
