The smarty template engine uses the built-in function foreach to loop out all array values, smartyforeach

The example in this article describes how to use smarty’s built-in function foreach, and shares it with everyone for your reference. The details are as follows:

Display file: index.php:

Copy code The code is as follows:

//Create smarty object
require_once("./libs/Smarty.class.php");
$smarty = new Smarty();

$arr1 = array("Beijing","Shanghai","Guangzhou");//Index array
$smarty->assign("arr1",$arr1);//Assign index array
$arr2 = array("city1"=>"Beijing","city2"=>"Shanghai","city3"=>"Guangzhou");//Associative array
$smarty->assign("arr2",$arr2);//Assign associative array
$arr3 = array(array("Beijing","Shanghai","Guangzhou"),array("Guan Yu","Zhang Fei","Beauty"));//Two-dimensional index array
$smarty->assign("arr3",$arr3);
$arr4 = array(array("c1"=>"Beijing","c2"=>"Shanghai","c3"=>"Guangzhou"),array("n1"=>"Guan Yu", "n2"=>"Zhang Fei","n3"=>"Beauty"));//Two-dimensional associative array
$smarty->assign("arr4",$arr4);

$smarty->display("temp.tpl");
?>

Template file: temp.tpl

Copy code The code is as follows:

smarty’s built-in function foreach, loops out array values

Example 1: One-dimensional index array

{foreach from=$arr1 item=temp}
{$temp}
{/foreach}

Example 2: One-dimensional associative array——>item is the key value and key is the key name. If the key is not retrieved, the extraction method is the same as the one-dimensional index array. Of course, the index array also has keys 0, 1, 2...

{foreach from=$arr2 item=temp key=k}
{$k}={$temp}
{/foreach}

Example 3: Two-dimensional index array——>Two loops are enough

{foreach from=$arr3 item=temp}
{foreach from=$temp item=value}
{$value}
{/foreach}

{/foreach}

Example 4: Two-dimensional associative array——>Just loop twice

{foreach from=$arr4 item=temp}
{foreach from=$temp item=value key=k}
{$k}={$value}
{/foreach}

{/foreach}
