Variables in regular expressions

[RobinTibbs]

pretty simple q which i can't seem to find an answer to, can i include a variable in a regular expression as such:

[code]$array = ( ....... );

foreach($array as $value) {
preg_match('($value)', <string>, $matches);
}[/code]

Yes. The same PHP syntax rules apply: variables are not interpolated in single quotes. Use double quotes or concatenation.
