shuffle($px);

$lib = unserialize(file_get_contents('390tghqwr890eghq9t23tgadfguiareg'));
$bys1 = array_filter(preg_split('/\.{2,}|\+/', strtolower($q)));
这里开始是第86行  foreach ($lib as $k1 => $v) {
   if (strlen(strpos($q, $lib[$k1][0])) > 0) {
        $bys2[$k1] = $lib[$k1][0];
  }
}
if (isset($bys1[1])) {
    if (isset($bys2)) {
        $bys3 = array_merge($bys1, $bys2);
    }
    else {
        $bys3 = $bys1;
    }
    $seg = array_values(array_unique($bys3));
}
elseif (isset($bys2)) {

我不懂PHP 请帮我解答并贴出源码
