Are those blog developers doing their own php-like template language? Non-also, in fact, these are PHP syntax, but not commonly used, these are PHP process control of the alternative syntax. Here we will give you a detailed talk about PHP Process Control alternative syntax. What is an alternative syntax? In short, it is some kind of grammatical alternative notation. Is there an alternative syntax for those grammars in PHP? Process Control (including if, while, Forforeach,SwitchThese statements have alternative syntax. The basic form of the substitution syntax: the left curly brace ({) is replaced by a colon (:), replace the right curly brace (}) withendif;，Endwhile;，endfor;，Endforeach; AndEndswitch; for example:<?phpif($a<0):?>is negative pull<?phpendif;?>The above statement is equivalent to<?phpif（$a<0) {?>is negative pull<?php}?>Why is the pure PHP code almost invisible?
