Indexed array

$res =array (' Shanghai ', ' Beijing ', ' Shenzhen ');

$smarty->assign ("arr", $res);

Associative arrays

$res 2=array (' city1 ' = ' Beijing ', ' city2 ' and ' Guangzhou ', ' City3 ' and ' Hunan ');

$smarty->assign ("arr2", $res 2);

Indexed two-dimensional arrays

$res 3 = Array (

Array (' Xiao Hsiao ', ' Changshan ', ' Wu Bei '), Array (' Sunshine ', ' Keep your ')

);

$smarty->assign ("Arr3", $res 3);

Associative two-dimensional arrays

$res 4 = Array (

Array (' id ' = ' 001 ', ' name ' = ' Zhang San ', ' email ' = ' zhangsan@1163.com '),

Array (' url ' = = ' http://www.baidu.com ', ' age ' = ' 28 ')

);

$smarty->assign ("Arr4", $res 4);

Associative two-dimensional array 2

$res 5=array (

' Emp1 ' =>array (' id ' = ' 001 ', ' name ' = ' Zhang San ', ' email ' = ' zhangsan@1163.com '),

' Emp2 ' =>array (' url ' = ' http://www.baidu.com ', ' age ' = ' 28 ')

Indexed array: element 1:<{$arr [0]}>, Element 2:<{$arr [1]}>, Element 3:<{$arr [2]}>

Associative array extraction 1 (not recommended): element 1:<{$arr 2[' city1 ']}>, element 2:<{$arr 2[' city2 ']}>, element 3:<{$arr 2[' city3 ']}>

Associative array extraction 2 (recommended): element 1:<{$arr 2.city1}>, element 2:<{$arr 2.city2}>, element 3:<{$arr 2.city3}>

Two-dimensional indexed arrays:

Element 1:<{$arr 3[0][0]}>

Element 2:<{$arr 3[0][1]}>

Element 3:<{$arr 3[0][2]}>

Element 4:<{$arr 3[1][0]}>

Element 5:<{$arr 3[1][1]}>

Associative two-dimensional array form 1:

id-<{$arr 4[0].id}>

name-<{$arr 4[0].name}>

email-<{$arr 4[0].email}>

url-<{$arr 4[1].url}>

age-<{$arr 4[1].age}>

Associative two-dimensional array form 2:

id-<{$arr 5.emp1.id}>

name-<{$arr 5.emp1.name}>

email-<{$arr 5.emp1.email}>

url-<{$arr 5.emp2.url}>

age-<{$arr 5.emp2.age}>

The browser displays the results:
