Comments (C++ and PHP Cross Reference Guide)

By Mike Prestwood

C++ versus PHP: A side by side comparison between C++ 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.

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.

C++: // or /* ... */

Commenting Code
C++ uses "//" for a single line comment and /* */ for a multiple line comment.

Syntax Example:

//Single line comment in MS (not ANSI compliant so do NOT use).

/* ANSI compliant single line comment. */

/*
Multiple line
comment.

*/

/*

* This is another popular

* way to write multi-line

* comments.

*/

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.
