<p>定义数组array（）</p>
<p>在数组array中用逗号分隔的键（key） => 值（value）</p>
<pre><code>array(
key => value,
key2 => value2,
key3 => value3,
)
</code></pre>
<p>使用短数组语法[]替代array()</p>
<pre><code><? php
$array = array(
"key1" => "v1";
"key2" => "v2";
"key3" => "v3";
)
?>
//短数组语法
$array = [
"key1" => "v1";
"key2" => "v2";
"key3" => "v3";
]
//没有键名的索引数组
$array = array("foo","bar","hello","world");
</code></pre>
