Here is a simple method for you to decrease your page size and increase your page load time with php.
It is only supported if you have a host where php is supported.
just like this
Imagine this is what we have in our index.php file - When we open it in web browser and view source code, it will remain just like this.
<html>

So, in first html it was total length of 188 bytes .
After we removed whitespaces and comments, the length decreased to 144 !!
If you want to remove whitespaces, and comments in your html page that you are hosted in a php supported host, then you can do this thing to decrease your page load time by decreasing unwanted quotes and comments, white spaces etc.
Here is the script for removeing whitespaces and comments with php.
<?php
function callback($buffer){
$buffer = str_replace("\n", "", $buffer);
$buffer = str_replace("//", "//", $buffer);
$buffer = str_replace("\t", "", $buffer);
$buffer = str_replace(chr(13), "", $buffer);
$buffer = ereg_replace("<!\-\- [\/\ a-zA-Z]* \-\->", "", $buffer);
$buffer = preg_replace('!/\*[^*]*\*+([^/][^*]*\*+)*/!', '', $buffer); // remove comments
$buffer = str_replace(array("\r\n", "\r", "\n", "\t", ' ', ' ', ' '), '', $buffer); // remove tabs, spaces, newlines, etc.
$buffer = str_replace('{ ', '{', $buffer); // remove unnecessary spaces.
$buffer = str_replace(' }', '}', $buffer);
$buffer = str_replace('; ', ';', $buffer);
$buffer = str_replace(', ', ',', $buffer);
$buffer = str_replace(' {', '{', $buffer);
$buffer = str_replace('} ', '}', $buffer);
$buffer = str_replace(': ', ':', $buffer);
$buffer = str_replace(' ,', ',', $buffer);
$buffer = str_replace(' ;', ';', $buffer);
return $buffer;
} ob_start("callback"); ?>
