从 HTML 文本区域读取数据，然后将数据插入到 PHP 数组中
我一直在尝试创建一个跟踪器，到目前为止一切都很顺利，只是我正在尝试开发的一项新功能让我感到困惑。我试图拥有它，以便启动跟踪器的人可以输入名称，并且跟踪器将抓取用户输入的名称并查找它们。
我能想到的实现这一目标的唯一方法是插入 $_POST['names'] 中的名称并将它们插入到一个数组中，但是当我这样做时，它只会在数组中创建一个索引。
这是我正在使用的代码：
$lol = array();
$l = array($_POST['names']);
foreach ($l as $textarea) {
array_push($lol, nl2br($textarea));
}
for ($a = 0; $a < count($lol); $a++) {
echo "index " . $a . ": " . $lol[$a];
}
结果是：
index 0: lol

我在带空格的文本字段中输入了上述内容。这是我正在使用的 HTML 文件：
<body>
<form name="form" action="test.php" method="GET">
<div align="center">
<textarea cols="13" rows="10" name="names"></textarea><br>
<input type="submit" value="lol">
</div>
</form>
</body>
所以我想我要问的是，是否可以让人在文本框中输入“Ron”、“Mark”、“Tommi”和“Daniel”，我可以插入“Ron”、“将“Mark”、“Tommi”和“Daniel”放入一个数组中，以便它们的索引分别为 [0, 1, 2, 3]，如果是这样，我将如何实现这一点？
I've been trying to create a tracker and everything is going smoothly thus far, just one new feature I'm trying to work on has me stumped. I'm trying to have it so the person who starts a tracker can enter names and the tracker will grab the names the user entered and look them up.
The only way that I can think of accomplishing this would be to insert the names from $_POST['names'] and insert them into an array, but when I do this, it only creates one index inside the array.
This is the code that I'm using:
$lol = array();
$l = array($_POST['names']);
foreach ($l as $textarea) {
array_push($lol, nl2br($textarea));
}
for ($a = 0; $a < count($lol); $a++) {
echo "index " . $a . ": " . $lol[$a];
}
The result of that is:
index 0: lol

I typed the above out in the text field with spaces. Here's the HTML file that I'm using as well:
<body>
<form name="form" action="test.php" method="GET">
<div align="center">
<textarea cols="13" rows="10" name="names"></textarea><br>
<input type="submit" value="lol">
</div>
</form>
</body>
So I guess what I'm asking is, is it possible to have a person put, say, "Ron", "Mark", "Tommi", and "Daniel" in the text box, could I insert "Ron", "Mark", "Tommi" and "Daniel" into an array so that their index would be [0, 1, 2, 3] respectively, and if so how would I achieve this?
