Hi there,
I am trying to find a way to count the number of times (if any) words are
inside a string. So I played around with ereg, preg_match_all and so on,
but could not put together a working code.
Can anybody help me on that?
This is the current code:
function count_words($str, $words) {
if(is_array($words)) {
foreach($words as $k = $word) {
$pattern[$k] = /\b($word)\b/is;
}
}
else {
$pattern = /\b($words)\b/is;
}
return ereg( $pattern, $str);
}
$words = 'php language';
$str = 'One language which is great is php. PHP works great!';
$num_hits = count_words($str, $word);
echo $num_hits;
I would like to get an case insensitive result. In this example: 3

Try this.
I am a bit lost on this one. Thank you for any help.

Maybe something like this?
?php
$words = array(php, language);
$str = 'One language which is great is php. PHP works great!';
$str = strtolower($str);
echo 'pre';
foreach($words as $word) {
echo 'word = ' .$word;
echo ' (' . substr_count($str, $word). )\n;
}
echo '/pre';
?
Although you'll run into a problem if your words array contains for
example 'air' which will match both 'air' and 'fair',
