Comments (PHP and Corel Paradox Cross Reference Guide)

By Mike Prestwood

PHP versus Corel Paradox: A side by side comparison between PHP and Corel Paradox.

 
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.

Comments

[Other Languages] 

Languages Focus

Commenting code generally has three purposes: to document your code, for psuedo coding prior to coding, and to embed compiler directives. Most languages support both a single line comment and a multiple line comment. Some languages also use comments to give instructions to the compiler or interpreter.

PHP:   # or // or /* ... */

Commenting Code
Use the multi-line to comment out large blocks of code and to write multiple line comments.

Syntax Example:
#This is a comment in PHP.

//This is too!

/*
This is a multi-line
comment.
*/
Corel Paradox:   ; and { ... }

Commenting Code
ObjectPAL uses ; for a single line comment and { } for a multiple line comment.

Syntax Example:  
;Single line comment.

{
Multiple line
comment.
}
