PHP如何编辑HTML元素的内容？

Question

Just like $('#elementid').html('html code'); but in PHP. Is there a way to change live content with PHP without reloading page? Tried

<?php
echo '<script type="text/javascript">
    $('#element').html('<p>I am a text</p>');      
</script>'
?>
<div id='element'>I will be changed!</div>

Is there any shorter way, that one also not works everytime.

Answer 1

$.post('test.php','',function(response){
   $('#element').html(res); 
});

test.php

$name = "sham";
echo "this is my variable $name";

Output of Html

<div id='element'>this is my variable sham</div>
