elseif/else if

elseif/else if

, as its name suggests, is a combination of and . Like , it extends an statement to execute a different statement in case the original expression evaluates to false. However, unlike , it will execute that alternative expression only if the conditional expression evaluates to true. For example, the following code would display , or :

`elseififelseelseififelse``elseif````php

$b) { echo "a is bigger than b"; } elseif ($a == $b) { echo "a is equal to b"; } else { echo "a is smaller than b"; } ?>

  There may be several s within the same
   statement.  The first
   expression (if any) that evaluates to
  true would be executed.  In PHP, it's possible to write
   (in two words) and the behavior would be identical
  to the one of  (in a single word).  The syntactic meaning
  is slightly different (the same behavior as C) but the bottom line
  is that both would result in exactly the same behavior.
 `elseif``if``elseif``else if``elseif`


  The  statement is only executed if the
  preceding  expression and any preceding
   expressions evaluated to
  false, and the current
   expression evaluated to
  true.

 ```php
<?php

/* Incorrect Method: */
if ($a > $b):
    echo $a." is greater than ".$b;
else if ($a == $b): // Will not compile.
    echo "The above line causes a parse error.";
endif;

<?php
/* Correct Method: */
if ($a > $b):
    echo $a." is greater than ".$b;
elseif ($a == $b): // Note the combination of the words.
    echo $a." equals ".$b;
else:
    echo $a." is neither greater than or equal to ".$b;
endif;
