perl to php conversion with =~& !~

[j0nxuser]

New to php5 and trying to figure out how to take a perl do/until loop (with like, eq and ne) and convert it to a php do/while loop.


do {
stuff;
more stuff;
}
until ((($title =~ /$level/i) && ($uid ne $rep)) ||
($top==1) ||
(($level eq "") && ($uid ne $rep)));



Not sure how to rewrite the perl until to php while and easily translate my like, not equal and equal.

I've been trying to play with strpos and preg_match and just not seeing it.

Any help/direction would be appreciated.

Thank you!

like is equivalent to stristr or strstr (case sensitive)

== is equivalent to === for numerics. but the == and === can be used in php for all variable types. === means == PLUS type equality.

ne is equivalent to != or !== (depending on type equivalency)

do ... until would be equivalent to do ... while but of course the condition would be reversed in logic.

the OR operator is || and the AND operator is &&

so translated your condition set would be

(
	(	(	stristr($level, $title) 
			&& 
			$uid != $rep
		) 
		||
		$top === 1
	) 
	||
		(
			empty($level) 
			&&
			$uid != $rep
		)
);

you could have used $level == "" as an alternative to empty(). empty() also tests to see whether the variable is set and whether it is null.
