Code Blocks (ASP Classic and PHP Cross Reference Guide)

By Mike Prestwood

ASP Classic versus PHP: A side by side comparison between ASP Classic and PHP.

 
Language Basics
 

Language basics is kind of a catch all for absolute beginner stuff. The items (common names) I chose for language basics is a bit random and include items like case sensitivity, commenting, declaring variables, etc.

Code Blocks

[Other Languages] 

Languages Focus

The rules for code blocks within a language dictate where you can declare variables, how you "bracket" code, etc.

ASP Classic:   End Xxx

In .ASP html pages, you embed ASP code between <% and %>.

ASP Classic code blocks are surrounded by statement ending keywords that all use End such as End Sub, End If, and WEnd.

Syntax Example:
<%
Sub x
End Sub
 
If x Then
End If
 
While x
WEnd
%>
PHP:   { }

In .PHP html pages, you embed PHP code between <?PHP and ?>.

For PHP, JavaScript, Java,and C++, I prefer to put the first { at the end of the first line of the code block as in the example above because I see morePHP codeformatted that way (and on PHP.Net).

PHP Alternative Syntax

Although I don't like to use it, PHP offers an alternative syntax for if, while, for, foreach, and switch. These code blocks are surrounded by statement ending keywords that all use End with camel caps such as endif, endwhile, endfor, endforeach,and endswitch.

Syntax Example:
<?PHP
$x = "Yes";
//Simple if
If ($x == "Yes")
echo "hello world";
 
//If with a block of code.
If ($x == "Yes") {
echo "Hello world";
  echo "I am a PHP coder!";
}
?>
