(period) symbol. 你也可以通過句號“.”后接數組鍵的方式來引用從php分配的關聯數組變量。 <table width="100%" border="0" cellpadding="0" cellspacing="0" class="EXAMPLE"><tr><td><div class="EXAMPLE"><b>Example 4-3. accessing associative array variables</b> <br/><strong>例4.3.訪問關聯數組變量 </strong> <table border="0" bgcolor="#E0E0E0" width="100%"><tr><td><pre class="PROGRAMLISTING">index.php:  $smarty = new Smarty; $smarty->assign('Contacts', array('fax' => '555-222-9876', 'email' => 'zaphod@slartibartfast.com', 'phone' => array('home' => '555-444-3333', 'cell' => '555-111-1234'))); $smarty->display('index.tpl');  index.tpl:  {$Contacts.fax}<br> {$Contacts.email}<br> {* you can print arrays of arrays as well *} {* 同樣可以用于多維數組 *} {$Contacts.phone.home}<br> {$Contacts.phone.cell}<br>  OUTPUT:  555-222-9876<br> zaphod@slartibartfast.com<br> 555-444-3333<br> 555-111-1234<br></pre> </td> </tr></table></div></td> </tr></table> ### Array indexes[數組索引] You can reference arrays by their index, much like native PHP syntax. 你也可以使用php原生語法風格引用數組索引。 <table width="100%" border="0" cellpadding="0" cellspacing="0" class="EXAMPLE"><tr><td><div class="EXAMPLE"> <p><b>Example 4-4. accessing arrays by index</b> <br/><strong>例4.4.</strong><strong>通過索引訪問數組 </strong> </p> <table border="0" bgcolor="#E0E0E0" width="100%"><tr><td><p><?php<br/> $smarty->assign('Contacts', array(<br/> '555-222-9876',<br/> 'zaphod@slartibartfast.example.com',<br/> array('555-444-3333',<br/> '555-111-1234')<br/> ));<br/> $smarty->display('index.tpl');<br/> ?><br/><br/> index.tpl source:<br/> {$Contacts[0]}<br /><br/> {$Contacts[1]}<br /><br/> {* you can print arrays of arrays as well *}<br/> {$Contacts[2][0]}<br /><br/> {$Contacts[2][1]}<br /></p> <p>This will output:<br/> 555-222-9876<br /><br/> zaphod@slartibartfast.example.com<br /><br/> 555-444-3333<br /><br/> 555-111-1234<br /></p></td> </tr></table></div></td> </tr></table> ### Objects[對象] Properties of objects assigned from PHP can be referenced by specifying the property name after the '->' symbol. 可以通過‘->‘符號后接指定屬性名的方式訪問php分配的對象屬性（這不是php訪問對象屬性的方法嘛，直說嘛:)）。 <table width="100%" border="0" cellpadding="0" cellspacing="0" class="EXAMPLE"><tr><td><div class="EXAMPLE"><b>Example 4-5. accessing object properties</b> <br/><strong>例4.5.訪問對象屬性</strong> <table border="0" bgcolor="#E0E0E0" width="100%"><tr><td><pre class="PROGRAMLISTING">name: {$person->name}<br> email: {$person->email}<br>  OUTPUT:  name: Zaphod Beeblebrox<br> email: zaphod@slartibartfast.com<br></pre> </td> </tr></table></div></td> </tr></table> <table width="100%" border="0" cellpadding="0" cellspacing="0"><tr><td width="33%" align="left" valign="top"><a href="language.variables.html">Prev</a></td><td width="34%" align="center" valign="top"><a href="index.html">Home</a></td><td width="33%" align="right" valign="top"><a href="language.variables.scopes.html">Next</a></td></tr><tr><td width="33%" align="left" valign="top">Variables<br/> 變量</td> <td width="34%" align="center" valign="top"><a href="smarty.for.designers.html">Up</a></td> <td width="33%" align="right" valign="top">Variable scopes<br/> 變量范圍 </td> </tr></table>
