i have made up a simple function to extract a number from a string..
I am not sure how good it is, but it works.
It gets only the numbers 0-9, the "-", " ", "(", ")", "."
characters.. This is as far as I know the most widely used characters for a Phone number.
<?php
function clean_phone_number($phone) {
if (!empty($phone)) {
preg_match_all('/[0-9\(\)+.\- ]/s', $phone, $cleaned);
foreach($cleaned[0] as $k=>$v) {
$ready .= $v;
}
var_dump($ready);
die;
if (mb_strlen($cleaned) > 4 && mb_strlen($cleaned) <=25) {
return $cleaned;
}
else {
return false;
}
}
return false;
}
?>
