APP . '/Template/' . $tpl; 126 | } 127 | $this->mset($array); 128 | 129 | if (!file_exists($this->_tpl)) { 130 | throw new \ZException("can not find tpl[{$this->_tpl}]", E_ERROR); 131 | } 132 | ob_start(); 133 | extract($this->_extract); 134 | include($this->_tpl); 135 | ob_flush(); 136 | } 137 | ... 138 | ``` 139 | 140 | 可以看到，render接受一个$array数组，然后将数组中的数据extract出来，这样一个原本是$array['tip']的数据在模板里边就能通过$tip访问了。而载入模板部分更简单，只是直接require。这是因为zan直接使用PHP来做模板的解释引擎。Template模板signup.php输出如下 141 | 142 | ```php 143 | 144 | 145 | 146 | ``` 147 | 148 | ## 基础库 149 | 一直在想哪些是web开发最常用的基础库，如何构建优雅的组件，以下是个开始，力争简单够用，让喜欢它的开发者能快速上手，同时让自己能这些组件优雅地开发复杂的应用。 150 | 151 | - 日志 152 | - 分模块、分级别 153 | - 配置简单(目前0配置) 154 | - 日志格式清晰易读 155 | - 应用简单 156 | - http 157 | - request 158 | - session 159 | - image 160 | -------------------------------------------------------------------------------- /Zan/Common.php: -------------------------------------------------------------------------------- 1 | init();
