你可以用IDE查找一下。

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);                    
}                
}

{
