php自定义函数集合

查找函数定义处

function func_dump($funcname)
{
    try {
        if (is_array($funcname)) {
            $func = new ReflectionMethod($funcname[0], $funcname[1]);
            $funcname = $funcname[1];
        } else {
            $func = new ReflectionFunction($funcname);
        }
    } catch (ReflectionException $e) {
        echo $e->getMessage();
        return;
    }
    $start = $func->getStartLine();
    $end =  $func->getEndLine();
    $filename = $func->getFileName();
    echo "函数{$funcname}被定义在【{$filename}】文件中第{$start}行到{$end}行\n";
}

二维数组排序函数

function sort_array(&$array, $keyid, $order = 'asc', $type = 'number')
{
    if (is_array($array)) {
        foreach ($array as $val) {
            $order_arr[] = $val[$keyid];
        }
        $order = ($order == 'asc') ? SORT_ASC : SORT_DESC;
        $type = ($type == 'number') ? SORT_NUMERIC : SORT_STRING;
        array_multisort($order_arr, $order, $type, $array);
    }
}
