<b>Some tips on the use of this editor:</b><br>
1. This is just a simple practice editor to help people in learn php.<br>
2. It is best used for things like developing functions or trying out new commands.<br>
3. Once you have developed some code, save the editor as a html document. You will then be able to open the html document later, press the submit button and it will call this editor, provided this script is still in the same place. You can then continue coding and save it off again.<br>
4. The radio buttons make different textareas active.<br>
5. The text boxes next to the radio buttons set the height of the associated textarea and over ride the default Height described in 7.<br>
6. The textbox with the # next to it specifies how many textareas you want to have<br>
7. The Height and Width textboxes specify the defaults for the active textarea.<br>
8. Some rough error flagging occurs if there is an error in your code.<br>
9. You can put any combination of php and html inside the textareas and it should work.
