Alternative notation for Process Control

PHP provides some alternative syntax for process control, including if, while, for,foreach , and switch. The basic form of substitution syntax is to replace the left curly brace ({) with a colon (:) and the right curly brace (}) into endif;,endwhile;,endfor;,Endforeach; and Endswitch;.

<php  if ($a  = =  5 ):  ?  >is to5<php  endif;  ? >

In the example above, the HTML contents "A is equal to 5" are nested in an if statement with an alternate syntax. The contents of the HTML are $a displayed only at equals 5 o'clock.

Alternative syntax can also be used in else and ElseIf . The following is an example of an if structure, including ElseIf and else , written in alternate syntax format:

<? PHP if $a  = =  5):    echo  "a equals 5 "    ; echo  " ..." ; ElseIf $a  = =  6):    echo  "a equals 6 "    ; echo  "!!!"  ; else:    echo  "A is neither 5 nor 6" ; endif ;? >

Note: It is not supported to mix two syntaxes within the same control block.

Use and or replace if else

isset($aa) andPrint("AA is set") orisset($as) andPrint("As is set") orPrint("as Not set");//equivalent toif(isset($aa))    Print("AA is set");ElseIf(isset($as))    Print("As is set");Else    Print("as Not set");
