Delimeters

[Chadian22]

foreach ($text as $key){ //line 48
$matched = preg_match('.*(pictureit\(.*\))+', $text[key($text)]); //line 49
print_r ($matched); //line 50
next($text); //line 51
} // line 52

I know that $text[key($text)] is the same thing as $key in this case ..

Warning: preg_match(): Unknown modifier '*' in C:\pear\bbcode.php on line 49

a delimeter is a character you use so that the preg functions know where your regex begins and ends.. these are used so that you can specify pattern modifiers.

preg_match('/[a-f0-9]+/i', $text);  // the "/" is our delimeter.
                                    // the regex begins after it, and ends at it, then "i" is a modifier
                                    // the i tells regex to be case insensitive

preg_match('/<tag>(.*?)<\/tag>/is', $code, $match); // same "/" delimeter.
                                                                // modifier "i" makes case insensitive.  s makes the . match newlines also

basically, it think the . is your delimeter, and the * character must come after some sort of pattern, so its giving an error since its the first character in the expression.

so whats wrong with what i have made ? i am saying that the '.' is any character and the *, means any character continous.

it thinks the . is your delimeter therefore its not actually part of the pattern.

basically just make it

preg_match('/.*(pictureit\(.*\))+/', $text[key($text)]);
