php如何改变标签的html值？

Question

In asp.net, I can have server controls like Textbox and etc.

Does PHP have web server control like asp.net?

I want to change a label html value.

Answer 1

Since there was no provided example you wanted help with here is a small snippet of how it would work.

 $user = "StackO";    
 <input type="text" placeholder="Example" name="custom" value="<?php echo $user; ?>">

This would put StackO as the value of the textbox. The value is the text of the textbox it's self.
