smarty模板引擎之分配数据类型 smarty模板引擎之分配数据类型

//分配基本数据
$smarty->assign("str","hello smarty!");
$smarty->assign("int",143);
$smarty->assign("double",12.1344);
$smarty->assign("bool",true);
$smarty->assign("bool2",false); 
字符串类型：<{$str}> <br/>
整型：<{$int}> <br/>
浮点型：<{$double}> <br/>
布尔类型真：<{$bool}> <br/>
布尔类型假：<{$bool2}> <br/> 

//索引数组

//关联数组
$res2=array('city1'=>'北京','city2'=>'广州','city3'=>'湖南');

//索引二维数组
$res3 = array(

索引数组：元素1:<{$arr[0]}>,元素2:<{$arr[1]}>,元素3:<{$arr[2]}> <br/> 
关联数组取法1(不推荐)：元素1:<{$arr2['city1']}>,元素2:<{$arr2['city2']}>,元素3:<{$arr2['city3']}> <br/> 
关联数组取法2(推荐)：元素1:<{$arr2.city1}>,元素2:<{$arr2.city2}>,元素3:<{$arr2.city3}> <br/> 
二维索引数组： 
元素1:<{$arr3[0][0]}>, 
元素2:<{$arr3[0][1]}>, 
元素3:<{$arr3[0][2]}>, 
元素4:<{$arr3[1][0]}>, 
元素5:<{$arr3[1][1]}> <br/> 
关联二维数组形式1： 
id-<{$arr4[0].id}>, 
name-<{$arr4[0].name}>, 
email-<{$arr4[0].email}>, 
url-<{$arr4[1].url}>, 
age-<{$arr4[1].age}> <br/> 
关联二维数组形式2： 
id-<{$arr5.emp1.id}>, 
name-<{$arr5.emp1.name}>, 
email-<{$arr5.emp1.email}>, 
url-<{$arr5.emp2.url}>, 
age-<{$arr5.emp2.age}><br/>
