PHP Manual
PrevAppendix A. Migrating from PHP/FI 2.0 to PHP 3.0Next

while syntax

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.
