PHP包括页眉或页脚位置

Question

I was hoping someone could help. I have just started to dabble with PHP includes for time saving in the future. For example I want to change the footer and header on a web page once (using include) instead of copying and pasting the code 30 or 40 times - oh no... a typo start again.

Which brings me to the question(s) where is it best to place this script?

<?php include("includes/headernav.html"); ?>

Can it be placed in a div, or should it be placed at the top of your code under the body?

If I want to make an image/banner include module. Can I

<?php include("includes/image.jpg"); ?> 

Or is best to wrap the image in html and apply like this?

<?php include("includes/imagewrapped.html"); ?>

Answer 1

Hope this helps:

<?php include("includes/ui_header.php"); ?>

My page content between header and footer

<?php include("includes/ui_footer.php"); ?>
