smarty中assign()這個函數是如何定義的

誰能帖出這個函數的代碼啊，以及它的原理

回複討論(解決方案)

你可以用IDE尋找一下。

smarty_internal_data.php

/**     * assigns a Smarty variable     *     * @param array|string $tpl_var the template variable name(s)     * @param mixed        $value   the value to assign     * @param boolean      $nocache if true any output of this variable will be not cached     * @param boolean $scope the scope the variable will have  (local,parent or root)     */    public function assign($tpl_var, $value = null, $nocache = false)    {        if (is_array($tpl_var)) {            foreach ($tpl_var as $_key => $_val) {                if ($_key != '') {                    if (isset($this->tpl_vars[$_key])) {                        $this->tpl_vars[$_key]->value = $_val;                        $this->tpl_vars[$_key]->nocache = $nocache;                    } else {                        $this->tpl_vars[$_key] = new Smarty_variable($_val, $nocache);                    }                }            }        } else {            if ($tpl_var != '') {                if (isset($this->tpl_vars[$tpl_var])) {                    $this->tpl_vars[$tpl_var]->value = $value;                    $this->tpl_vars[$tpl_var]->nocache = $nocache;                } else {                    $this->tpl_vars[$tpl_var] = new Smarty_variable($value, $nocache);                }            }        }    }
