Hello. Quick question. I have several thousand emails pulled in from several email boxes throuph php imap and I need to search each subject with an array of search terms which returns a bitmask, one bit for each index of the array. 1 = found, 0 = not found.
So, if I have the phrase "my car is red" and I pass in the array "car,blue,red,green,sky,my,house,is" I will get a bitmask back of "10100101".
my solution:
public function stringSearchReturnBitMask(array $arrSearch, $strString) {
$strReturn = "";
foreach($arrSearch as $strSearch) {
$strReturn .= stripos($strString, $strSearch) !== false?"1":"0";
}
return $strReturn;
}
Is there a more efficient way of doing this? I don't like the idea of a loop nested in a loop but I'm not aware of a preg_match solution that will do it for me and less taxing. I was thinking of imploding the array with "|" into a preg_match type function but how would I have it return a bitmask and would it actually be more efficient?
