Uploading Files with PHP

This script will allow you to upload files from your browser to your hosting, using PHP. The first thing we need to do is create an HTML form that allows people to choose the file they want to upload. 

<form enctype="multipart/form-data" action="upload.php" method="POST"> 
<lable> Please choose a file: </lable>
<input name="uploaded" type="file" /><br /> 
<input type="submit" value="Upload" /> 
</form> 
 
This form sends data to the file "upload.php". Then we can easily get the uploaded information using file function in upload.php.

How To Optimize Your Site With GZIP Compression

Compression is a simple, the effective way to save bandwidth and speed up your sites. I hesitated when recommending gzip compression when speeding up your javascript because of problems in older browsers.

Most of my traffic comes from the modern browsers, and quite frankly, most of my users are fairly technology-savvy. I don't want to slow everyone else down because somebody is the chugging along on IE on Windows Operating Systems. Google and Yahoo browsers are using gzip compression.

Before we start, I should explain what content encoding is. When you request a file like http://www.gmail.com/index.html, your browser talks to a web server.
