I tried the code of William, Thanks brother.
我尝试了威廉的代码，谢谢兄弟。
but it's not working as a simple button I have to add form with method="post". Also I have to write submit instead of button.
但它不是一个简单的按钮，我必须添加带有 method="post" 的表单。另外我必须写提交而不是按钮。
here is my code below..

<form method="post">
<input type="submit" name="test" id="test" value="RUN" /><br/>

You are trying to call a javascript function. If you want to call a PHP function, you have to use for example a form:
您正在尝试调用 javascript 函数。如果你想调用一个 PHP 函数，你必须使用例如一个表单：
<form action="action_page.php">
First name:<br>
<input type="text" name="firstname" value="Mickey">
<br>
Last name:<br>
<input type="text" name="lastname" value="Mouse">
<br><br>
<input type="submit" value="Submit">
</form>

So if you want do do a asynchron call, you could use 'Ajax' - and yeah, that's the Javascript-Way. But I think, that my code example is enough for this time :)
所以如果你想做一个异步调用，你可以使用'Ajax' - 是的，这就是Javascript-Way。但我认为，这次我的代码示例已经足够了:)

<a href="home.php?click=1" class="btn">Click me</a>
<?php
if($_GET['click']){
doSomething();
}
?>
But is better to use JS and with ajax to call function!
但是最好使用JS和ajax来调用函数！

No Problem You can use onClick()function easily without using any other interference of language,
没问题您可以onClick()轻松使用功能，而无需使用任何其他语言干扰，
<?php
echo '<br><Button onclick="document.getElementById(';?>'modal-wrapper2'<?php echo ').style.display=';?>'block'<?php echo '" name="comment" style="width:100px; color: white;background-color: black;border-radius: 10px; padding: 4px;">Show</button>';
?>

You can use isset().
您可以使用isset().
<form method="post">
<input type="submit" name="test" id="test" value="RUN" />
</form>
<?php
function testfun()
{
echo "Your test function on button click is working";
}
if(isset($_POST('submit')))
{
testfun();
}
?>
