"false" is a keyword, same as "true" and "null".


> This tiny script:
> <?php
> session_start();
> $ineligibleFlag = FALSE;

This assigns $ineligibleFlag the boolean value of 0 or "false"

> if ( $ineligibleFlag === FALSE ) echo 'it is false<br />';

This tests to see if $inelegibleFlag is boolean and false (triple equals 
requires type and value to match), which is exactly what you just 
assigned it to, so you get a match.

Try assigning $ineligibleFlag = 0, or '0' , or '' (empty string) and see 
the various results you get.

> $_SESSION['ineligibleFlag'] = FALSE;
> print_r( $_SESSION );
>
> produces this output:
> it is false
> Array ( [ineligibleFlag] => )
