将一个或多个单元压入数组的末尾（入栈）

<para>

<function>array_push</function> 将
|
||
<parameter>array</parameter> 当成一个栈，并将传入的变量压入
|
||
<parameter>array</parameter> 的末尾。<parameter>array</parameter>
|
||
的长度将根据入栈变量的数目增加。和如下效果相同：
|
||
<programlisting role="php">
|
||
<![CDATA[
|
||
<?php
|
||
$array[] = $var;
|
||
?>
|
||
]]>
|
||
</programlisting>
|
||
并对每个 <parameter>var</parameter> 重复以上动作。
|
||
</para>
|
||
<para>
|
||
返回数组新的单元总数。

<?php

$stack = array("orange", "banana");
|

array_push($stack, "apple", "raspberry");
|
||
print_r($stack);
|
||
?>
|
||
]]>
|
||
</programlisting>
|
||
<para>
|

本例将使 <varname>$stack</varname> 具有如下单元：

</para>

Array
|

(
|
||
[0] => orange
|
||
[1] => banana
|
||
[2] => apple
|
||
[3] => raspberry
|

)

|

</screen>

</example>

</para>

<note>
|

<simpara>
|
||
如果用 <function>array_push</function> 来给数组增加一个单元，还不如用
|
||
<literal>$array[] = </literal>，因为这样没有调用函数的额外负担。
|
||
</simpara>
|
||
</note>
|
||
<note>
|
||
<simpara>
|
||
如果第一个参数不是数组，<function>array_push</function>
|
||
将发出一条警告。这和
|
||
<literal>$var[]</literal> 的行为不同，后者会新建一个数组。

|

<para>
|

参见 <function>array_pop</function>，<function>array_shift</function>
|
||
和 <function>array_unshift</function>。
