Answer 1

Create a lookup array for your data:

$str = '"Harry":"12345","Biswas":"789456","garry":"56894"';

$passwords = array();
foreach( str_getcsv( $str) as $entry) {
    list( $name, $pw) = explode( ':', $entry);
    $passwords[$name] = $pw;
}

Then, just use their name as the key to find their password:

$fh = "Harry";
echo $passwords[$fh]; // 12345
