usage example of smarty built-in function foreach, smartyforeach

The example in this article describes the usage of smarty’s built-in function foreach. Share it with everyone for your reference. The details are as follows:

Output file: index.php

Copy code The code is as follows:

require_once('libs/Smarty.class.php');
$smarty = new Smarty();
$smarty->setTemplateDir($_SERVER['DOCUMENT_ROOT']."/php/templates/");
$smarty->setCompileDir($_SERVER['DOCUMENT_ROOT']."/php/templates_c/");
$smarty->setCacheDir($_SERVER['DOCUMENT_ROOT']."/php/cache/");
$smarty->caching = false;

$name = array("Xi Yang Yang", "美 Yang Yang", "Lazy Yang", "Ha Ha Ha");
$family = array("husband"=>"Xi Yangyang","wife"=>"Mei Yangyang","boy"=>"Lazy Yang","girl"=>"Hahaha");
$smarty->assign("name",$name);
$smarty->assign("family",$family);

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

Template file: temp.htm

Copy code The code is as follows:

{foreach $name as $value}
{$value}
{/foreach}

---

{foreach $family as $family_name}
{$family_name@key} = {$family_name}
{/foreach}


{foreach from=$family item=f_name key=k}
{$k} = {$f_name}
{/foreach}

---

There are roughly two forms of array output methods:

(1) One is smarty 2’s {foreach from=array variable name item=array value}.
(2) The output method of smarty 3 is consistent with that of PHP. The above example does not add $key. When you need to output the key name, use the form @key in the example; you can use the form $key=>$value.

In addition, if you only take a certain value in the array, you can output it directly, such as {$family.husband} for associative arrays, {$name[0]} for index arrays, etc.

I hope this article will be helpful to everyone’s PHP programming design.
