Question

I have a question. I’m using a script that will check the domain in my database. If got a match then it will be TRUE.

while( $row = mysql_fetch_array($result) ) {       
    echo var_dump($phpgsb->doLookup($row['origin'])). " - ". $row['origin'];
    echo "<br>";
}

$row['origin'] is an array of domain. Example:

test.com
lol.com
what.com
blabla.com

And the output I’m getting is:

bool(false) - test.com.
bool(false) - lol.com.
bool(true) - what.com.
bool(false) - blabla. 

what.com is in my database so it’s a TRUE. Now the problem is I don’t know how to use/capitalize/exploit (I’m sorry my English is not good) the true result. Is there anyway I could create in the while loop:

if (bool == true) {
    only echo the true result
}

I have did this with associative arrays results. I don’t know how to do it boolean.

If you’re trying to find the record that $phpgsb->doLookup($row['origin']) returns true when passing in the current row of your db query, do:

while ($row = mysql_fetch_array($result)) {
    if ($phpgsb->doLookup($row['origin']) === true) {
        echo var_dump($phpgsb->doLookup($row['origin'])). " - " . $row['origin'];
        echo "<br>";
    }
}

Note the ===, which checks type AND value. == is a falsy check and therefore could return conditions that evaluate 0 == false (or 1 == true) as a true statement(s).
