Re: [PHP-DEV] PHP 4.0 Bug #7808 Updated: variable value triggerd by function From: Adam Wright (adam <email protected>)
Date: 11/14/00

>From your example 1, it looks you want the value of $time to be the value
returned by time() at any point where you deference the $time variable (as
opposed to $time being a reference to the function), so in effect, the
variable becomes a macro for "run this function and assign its returned
value to this variable". Why you'd want this is beyond me, as its more
likely to get confusing. Why not just write it out in full (use ($time =
time())? Or, as already suggested, $time="time"; $time();.

I can't think of a convincing argument for your method. For example, what
happens when the function you assigned takes parameters?
