<? Php else:?>


<? Php the_content (_ ('continue reading → ', 'thebox');?>
<? Php wp_link_pages (array ('before' =>'

'. _ ('Pages:', 'thebox'), 'after' =>'

');?>


<? Php endif;?>

What do the colons and endif after else represent? I have never met a Cainiao, so I just googled it to understand that this is an alternative syntax for php,

Colon (:) is equivalent to Left curly braces ({), and endif is equivalent to right curly braces (});

For example:

The code is as follows:


<? Php if ($ a <0):?>


Is a negative number.

The code is as follows:


<? Php endif;?>


The preceding statement is equivalent

The code is as follows:


<? Php if ($ a <0) {?>


Is a negative number.

The code is as follows:


<? Php }?>

Which of the following statements in PHP have alternative syntaxes?

Process control (including if, while, forforeach, switch) statements have alternative syntax.

The basic form of alternative syntax:

Replace Left curly braces ({) with colons (:), and change right curly braces (}) with endif;, endwhile;, endfor;, endforeach; and endswitch;

<? Php while (expr):?>

  • <? Php endwhile;?>
