PHP Comments

Comments in PHP

In PHP, comments are lines of code that are ignored by the PHP interpreter. They are used to explain the purpose of code, document functionality, and improve readability. Here's a breakdown of comments and syntax in PHP:

Comments can be used to:

• Let others understand your code

• Remind yourself of what you did - Most programmers have experienced coming back to their own work a year or two later and having to re-figure out what they did. Comments can remind you of what you were thinking when you wrote the code

• Leave out some parts of your code

PHP supports several ways of commenting:

Example

     <!DOCTYPE html>
     <html>
    <body>
             
     <?php
     // This is a single-line comment
            
     # This is also a single-line comment
            
     /* This is a
      multi-line comment */
     ?>
                         
     </body>
     </html>

• Single Line Comments

Single line comments start with //.

Any text between // and the end of the line will be ignored (will not be executed).

• Multi-line Comments

Multi-line comments start with /* and end with */.

Any text between /* and */ will be ignored.
