array函数怎么用

array(value1,value2,value3,etc.);

array(key=>value,key=>value,key=>value,etc.);

<?php
//创建一个索引数组
$teacher = array("西门","灭绝","无忌");
$len = count($teacher);
for ($i = 0; $i < $len; $i++)
{    
echo $teacher[$i];    
echo "<br>";
}
echo "<br>";
//创建一个关联数组并输出
$teacher = array("class" => "php中文网","name" => "peter","age" => "30");
echo $teacher[&#39;class&#39;]. "有个老师名字叫" .$teacher[&#39;name&#39;]. ",他有" .$teacher[&#39;age&#39;]. "岁了";
?>
