  • dump() 把数组以数组格式数组,有益于调试

    function dump($vars, $label = '', $return = false){
        if (ini_get('html_errors')) {
            $content = "<pre>\n";
            if ($label != '') {
                $content .= "<strong>{$label} :</strong>\n";
            }
            $content .= htmlspecialchars(print_r($vars, true));
            $content .= "\n</pre>\n";
        } else {
            $content = $label . " :\n" . print_r($vars, true);
        }
        if ($return) { return $content; }
        echo $content;
        return null;
    }

    array_remove_empty()去除数组中为空的元素

    function array_remove_empty(& $arr, $trim = true){
        foreach ($arr as $key => $value) {
            if (is_array($value)) {
                array_remove_empty($arr[$key]);
            } else {
                $value = trim($value);
                if ($value == '') {
                    unset($arr[$key]);
                } elseif ($trim) {
                    $arr[$key] = $value;
                }
            }
        }
    }

    array_chunk() php默认函数 作用是把函数平均分组
