Note that if you've used the "x" pattern modifier in your regex, you'll want to
make sure you escape any whitespace in your string that you *want* the pattern to match.
A simplistic example:
$phrase = 'a test'; // note the space
$textbody = 'this is a test';
// Does not match:
preg_match('/' . preg_quote($phrase) . '$/x', $textbody);
function preg_quote_white($a) {
$a = preg_quote($a);
$a = str_replace(' ', '\ ', $a);
return $a;
}
// Does match:
preg_match('/' . preg_quote_white($phrase) . '$/x', $textbody);
