HTML元素数组，名称=“ something []”或名称=“ something”？

PHP使用方括号语法将表单输入转换为数组，因此使用

name="education[]"

$educationValues = $_POST['education']; // Returns an arrayprint_r($educationValues); // Shows you all the values in the array

因此，例如：

<p><label>Please enter your most recent education<br>    <input type="text" name="education[]"></p><p><label>Please enter any previous education<br>    <input type="text" name="education[]"></p><p><label>Please enter any previous education<br>    <input type="text" name="education[]"></p>

将为您提供

$_POST['education']

在Javascript中，通过id获取元素更有效。

document.getElementById("education1");

ID不必与名称匹配：

<p><label>Please enter your most recent education<br>   <input type="text" name="education[]" id="education1"></p>
