You are violating 2 rules here of how to use regular expressions.
#1 Regular expressions always needs 2 arguments. 1: Pattern to be matched and
2: String in which defined pattern is to be matched.
Here you missed 2nd arguments that is why parser gives ) => / error.
#2 Quote (double or single) is almost must in regular expressions specially
when you want to expand modifiers (?, ., + etc)
If you don't use quote then code will work but pattern will be treated as a
constant and php will go to parse it and may generate "Notice" if such can
not be found. Below is the correct way to use this regular expression
function.
$trans_text=preg_match("/<div id=result_box dir=ltr>(.+?)<\/div>/",
$ss__strToBeLookedIn);
Also note "</div> => <\/div>", because php thinks that "/" is end of boundary
which is not actually :)
Thanks
