我想在 display.php 页面上的选择列表框中显示选定的值。那么如何使用$_GET[]数组访问 display.php 页面上的选定值。

If you want PHP to treat $_GET['select2']as an array of options just add square brackets to the name of the select elementlike this: <select name="select2[]" multiple …
如果您希望 PHP 将其$_GET['select2']视为一组选项，只需在select 元素的名称中添加方括号，如下所示：<select name="select2[]" multiple …
Then you can acces the array in your PHP script
然后你可以访问你的 PHP 脚本中的数组
<?php
header("Content-Type: text/plain");
foreach ($_GET['select2'] as $selectedOption)
echo $selectedOption."\n";
$_GETmay be substituted by $_POSTdepending on the <form method="…"value.
$_GET可以替换为$_POST取决于<form method="…"值。

You can iterate it directly like this
你可以像这样直接迭代它
foreach ($_GET['select2'] as $value)
echo $value."\n";
or you can do it like this
或者你可以这样做
$selectvalue=$_GET['select2'];
foreach ($selectvalue as $value)
echo $value."\n";

// CHANGE name="select2" TO name="select2[]" THEN
<?php
$mySelection = $_GET['select2'];
$nSelection = count($MySelection);
for($i=0; $i < $nSelection; $i++)
{
$numberVal = $MySelection[$i];
if ($numberVal == "11"){
echo("Eleven");
}
else if ($numberVal == "12"){
echo("Twelve");
}
...

}

You could do like this too. It worked out for me.
你也可以这样做。它对我有用。
<form action="ResultsDulith.php" id="intermediate" name="inputMachine[]" multiple="multiple" method="post">
<select id="selectDuration" name="selectDuration[]" multiple="multiple">
<option value="1 WEEK" >Last 1 Week</option>
<option value="2 WEEK" >Last 2 Week </option>
<option value="3 WEEK" >Last 3 Week</option>
<option value="4 WEEK" >Last 4 Week</option>
<option value="5 WEEK" >Last 5 Week</option>
<option value="6 WEEK" >Last 6 Week</option>
</select>
<input type="submit"/>
</form>
Then take the multiple selection from following PHPcode below. It print the selected multiple values accordingly.
然后从下面的PHP代码中进行多项选择。它相应地打印选定的多个值。
$shift=$_POST['selectDuration'];
print_r($shift);

I fix my problem with javascript + HTML. First i check selected options and save its in a hidden field of my form:
我用 javascript + HTML 解决了我的问题。首先，我检查选定的选项并将其保存在表单的隐藏字段中：
for(i=0; i < form.select.options.length; i++)
if (form.select.options[i].selected)
form.hidden.value += form.select.options[i].value;
Next, i get by post that field and get all the string ;-) I hope it'll be work for somebody more. Thanks to all.
接下来，我通过发布该字段并获取所有字符串；-) 我希望它对更多人有用。谢谢大家。
