foreach garbled

$load _list is a two-dimensional array, the USER_NAME value is taken out of the first two characters, followed by asterisks instead, but encountered in Chinese characters garbled, set the header () function, also useless, to solve the solution, thank you!

if ($i >1) {
$temp [$i]= ' * ';
}
}
}
