Help with reg expression

[litton1]

Hi all, please could you give me some help with this regular expression?
I am (trying) using preg_match to see if there are any illegal operators in a string but think I may be using the regular expression wrong

$pattern = '^["/OR/"]| ["/AND/"]|["/And/"]| ["/\+/"]|["/\&/"]|["/\'/"]| ["/#/"]$';
$badOper = preg_match($pattern, $strToCheck);

but i obviously don’t want words like Andrea, ordinance to show up

A problem with no solution is a problem viewed from the wrong angle

i still dont get the use of the REgExp can u be a bit more clear???

Known is handfull, Unknown is worldfull

Yes sorry, I don’t want any of the words such as ‘AND’ ‘OR’ and I don’t want apostrophise, hash or equals etc. if any of these words or operators/symbols are in the string $strToCheck then true should be returned. Hope that is a bit clearer and thanks for your reply

why not use strpos()

Known is handfull, Unknown is worldfull

try

$pattern = "/\band\b|\bor\b|[\'\#\=\+]/i";
$badOper = preg_match($pattern, $strToCheck);

Hi again and thanks for both of your replies. I think vbkris, using strpos() would be faster in this instance but I wanted to use a reg expression as I need the practice :-( , that did the trick thanks jemminger, I can take that now and make it fit my needs. Thanks again both of you
