the most important thing: do not use the javascript keyword delete(JavaScript delete operator help) as function name! Your function (and thus onclick) won't work because of this! Change it to something appropriate like deleteRecordand you could use php only to output the ID, like:
最重要的是：不要使用javascript关键字delete（JavaScript delete operator help）作为函数名！因此，您的功能（以及 onclick）将无法工作！将其更改为适当的内容，例如deleteRecord，您可以仅使用 php 来输出 ID，例如：
<html>
<head>
<title></title>
<script type="text/javascript">
function deleteRecord()
{
if (confirm("Do you wanto delete the player?")) {
alert("player Deleted");
}
else {
alert("Record not deleted");
}
}
</script>
</head>
<body>
<a href="delete.php?player_id=<?php echo $player_id ?>" onclick='deleteRecord();'>Delete record?</a>
</body>
</html>

I found a pretty good solution. However, It adds a little extra to your code. I do not recommend using this method too much. I am a new PHP developer, so there are probably somethings this method can and cannot do.
我找到了一个很好的解决方案。但是，它为您的代码添加了一些额外的内容。我不建议过多地使用这种方法。我是一个新的 PHP 开发人员，所以这个方法可能有一些可以做和不能做的事情。
also I cannot seem to prevent this method from loading a new page, so the best way is to add your php to the beginning of the file. This is also a better solution for using AJAX (my opinion)
我似乎也无法阻止此方法加载新页面，因此最好的方法是将您的 php 添加到文件的开头。这也是使用 AJAX 的更好解决方案（我认为）
if the current file is index.php...
如果当前文件是 index.php...
make a form tag element
制作表单标签元素
'<form action="index.php" method="post">'
'<input type="submit" name="helloWorld" value="hello World">'
'</form>'
here you will display the content of what you are trying for, with a click
在这里，您将通过单击显示您正在尝试的内容
'<article>'
'<?php echo myFunction(); ?>'
'</article>'
this next php markup can go anywhere as long as it it is in the same file... Unless you know how to work around. Best place is before the HTML.
下一个 php 标记可以放在任何地方，只要它在同一个文件中......除非你知道如何解决。最好的地方是在 HTML 之前。
'<?php '
'function myFunciton() {'
'if (isset($_POST[helloWorld])) {'
'echo "hello world"; ... your methods'
'}'
'}'
or you could directly access it without using a function
或者你可以不使用函数直接访问它
<body>
<form action="index.php" method="post">
<input type="submit" name="hello" value="hello">
<input type="submit" name="goodBye" value="goodBye">
</form>
<article>
<?php
if (isset($_POST[hello])) {
echo "This happens if you click hello";
}
if (isset($_POST[goodBye])) {
echo "This happens if you click goodBye";
}
?>
</article>
</body>
