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'. 4 |
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 ?> 7 |
