Just like with if..endif, the syntax of while..endwhile has changed as well:
| Example A-7. Migration: old while..endwhile syntax while ($more_to_come);
    ...
endwhile; | 
| Example A-8. Migration: new while..endwhile syntax while ($more_to_come):
    ...
endwhile; | 
| Warning | 
| If you use the old while..endwhile syntax in PHP 3.0, you will get a never-ending loop. |
