CommentsPHP ManualPrevChapter 5. Basic syntaxNextComments
PHP supports 'C', 'C++' and Unix shell-style comments. For example:
1
2 <?php
3 echo "This is a test"; // This is a one-line c++ style comment
4 /* This is a multi line comment
5 yet another line of comment */
6 echo "This is yet another test";
7 echo "One Final Test"; # This is shell-style style comment
8 ?>
9
The "one-line" comment styles actually only comment to the
end of the line or the current block of PHP code, whichever
comes first. 1
2 <h1>This is an <?# echo "simple";?> example.</h1>
3 <p>The header above will say 'This is an example'.

You should be careful not to nest 'C' style comments, which can
happen when commenting out large blocks. 1
2 <?php
3 /*
4 echo "This is a test"; /* This comment will cause a problem */
5 */
6 ?>
