从PHP赋值的变量

赋值的变量以美元符号 ($) 开头。

变量赋值

  • PHP代码:
$this->cs->assign('firstname', 'Doug');
$this->cs->assign('lastname', 'Evans');
$this->cs->assign('meetingPlace', 'New York');

$this->cs->display('index.tpl');

index.tpl模板源码:

Hello {$firstname} {$lastname}, glad to see you can make it.
<br />
{* this will not work as $variables are case sensitive *}
This weeks meeting is in {$meetingplace}.
{* this will work *}
This weeks meeting is in {$meetingPlace}.

输出:

Hello Doug Evans, glad to see you can make it.
<br />
This weeks meeting is in .
This weeks meeting is in New York.

数组赋值

  • 可以通过点号“.”来使用赋值的数组变量。

PHP代码:

$this->cs->assign('Contacts',
    array('fax' => '555-222-9876',
          'email' => 'zaphod@slartibartfast.example.com',
          'phone' => array('home' => '555-444-3333',
                           'cell' => '555-111-1234')
                           )
         );
$this->cs->display('index.tpl');

index.tpl模板代码:

{$Contacts.fax}<br />
{$Contacts.email}<br />
{* you can print arrays of arrays as well *}
{$Contacts.phone.home}<br />
{$Contacts.phone.cell}<br />

输出:

555-222-9876<br />
zaphod@slartibartfast.example.com<br />
555-444-3333<br />
555-111-1234<br />

数组下标

  • 你可以通过下标来使用数组,和PHP语法一样。

PHP代码:

$this->cs->assign('Contacts', array(
                           '555-222-9876',
                           'zaphod@slartibartfast.example.com',
                            array('555-444-3333',
                                  '555-111-1234')
                            ));
$this->cs->display('index.tpl');

index.tpl模板代码:

{$Contacts[0]}<br />
{$Contacts[1]}<br />
{* you can print arrays of arrays as well *}
{$Contacts[2][0]}<br />
{$Contacts[2][1]}<br />

输出:

555-222-9876<br />
zaphod@slartibartfast.example.com<br />
555-444-3333<br />
555-111-1234<br />

对象

  • 从PHP赋值的对象的属性和方法,可以通过->来使用。

PHP代码:

$this->cs->assign('person', $this);
$this->cs->display('index.tpl');

index.tpl模板代码:

name:  {$person->name}<br />
email: {$person->email}<br />

输出:

name:  Zaphod Beeblebrox<br />
email: zaphod@slartibartfast.example.com<br />
