i have piece of code that works fine on my local test server but on live server for some reason it does not.
Php version on live server is 5.1.6.
$subject = 'random words to check';
$terms = explode(' ', 'word1 word2 check');
$wordIndex = array_flip(preg_split('/\P{L}+/u', mb_strtolower($subject), -1, PREG_SPLIT_NO_EMPTY));
foreach ($terms as $term) {
if (isset($wordIndex[$term])) {
echo "match>".$term;
}
}
First employ some basic debugging to discover what’s happening on each system
