Alternative syntax in PHP

Today looked at the WordPress code, there are some rare php substitution syntax,

 
  
		
			
 
  
			
 
  '' . __ (' Pages: ', ' Thebox '), ' after ' => ');?>
		
	
 
  

What does the colon and endif behind the else represent? Rookie one, have not seen, so Google a bit, just understand that this is the substitution of PHP syntax,

A colon (:) equivalent to a left curly brace ({), endif equivalent Yu Yu curly braces (});

Let's take an example:

It's negative, pull.

The above statement is equivalent to

It's negative, pull.

Do the syntax in PHP have alternative syntax?
Process Control (including If,while,forforeach,switch) These statements have alternative syntax.

The basic form of alternative syntax:
The left curly brace ({) is replaced with a colon (:), and the right curly brace (}) is replaced with Endif;,endwhile;,endfor;,endforeach; and Endswitch;

While substitution syntax:

Loop dot What

Other alternative grammars can be analogous.
