Question

If i’ve database my_table (id,word) as following

and i’ve some posted text called $name then i want to know if $name have any word like words i’ve stored in my database my_table (id,word)

so i’m using this code

$name = "Hello lovely world"; // no bad words

$sql    = "SELECT * FROM my_table";
$result = mysql_query($sql);

$commentArray = explode(" ", $name);
$counter      = count($commentArray);
$check        = 0;

while ($row = mysql_fetch_assoc($result)) {

    for ($i == 0; $i < $counter; $i++) {

        if (strcasecmp($commentArray[$i], $row['word'])) {
            $check = 1;
        }

    }

}

if ($check == 1) {
    echo "banned";
    exit;
}
else {
    echo "passed";
}

however it always results in echo "banned"; even if i $name is clear of any bad words i’ve stored in my_table so there might be something wrong here !

strcasecmp returns 0 when it matches (PHP manual), so you should edit your code:

if (strcasecmp($commentArray[$i], $row['word']) == 0)

Furthermore, you have a syntax error in your for loop. It should be for ($i = 0; ...
