Text counter in PHP

A counter is an essential part of a site to know how many people are coming to site. Here is an easy way to make a counter. All you need is access to PHP and be able to chmod a directory. We’re going to save the amount of hits in a .dat file, so you don’t even need a mySQL database. First off, you have create a directory and CHMOD it 777 so PHP can write the counter.dat file.

Here is what we have to do:

1. Use the file_exists() function in PHP and see if the counter.dat file exists. If it does, then open the file using the PHP fopen() function.
2. Use the PHP fgets() function to find the number of hits there and save it in a variable.
3. Add one to the variable.
4. Close the file.
5. Display the number of hits.
6. Open the counter.dat file using the fopen() function and save it as a variable.
7. Use the PHP fputs() function to insert the new number of hits.
8. Close the file.
9. If the counter.dat file doesn’t exist, then use the fopen() function and declare it as a variable.
10. Use the Fputs() function and put a “1″ in there.
11. Print out that 1 person has come to the page and then close the file.

Changing Web Hosts ? Step-By-Step Guide

Every webmaster cringes at the thought of moving hosts. Like moving your home it can be messy and sometimes problems arise. But if you follow these simple steps, your move will be less painful.

Backup Backup Backup
If you’ve been diligent with your backups, you’ve got a lot of insurance to fall back on yet always make the latest backup. If you haven’t, before you do anything else, do a backup now. Backup anything and everything you can and don’t forget your database if your site relies on it. Save at least 2 copies and store them separately. One for you to work with, and the other as an archive. Do not underestimate how easy it is to copy over these files as you make changes or simply mess it up.

If you’re moving to a host who has as different control panel, make a manual backup by downloading all your files because different control panels may not be able to restore the backups made by your old host. They also have different directory structures so your file trees will be in a mess. If you need to, make a small note file with notepad with memos for you to remember the old server configurations. This will help you as you make changes on your new host server and save the confusion moving back and forth between hosts. Remember to make the correct transfer type (ASCII or Binary) as you download. If your download is not right chances are you’ll have a tough time getting your site to work on the new host server.

If server logs are especially important, remember to backup those too. There is no good way of moving logs yet because different hosts may log statistics differently. So the best thing to do is to download it and use a log analyzer on your computer to make references to later on.

Create Random Text in PHP

Want to put a random quote on your site? Or randomize some other aspect of your site? It’s easy. You’ll want to use PHP or some other server-side scripting language instead of a client-side scripting language like JavaScript. Server-side languages write the content to the page in html before it ever leaves the server. Search engines will be able to read the content on your page, but with JavaScript they cannot, so you lose any content value of the random code. Also, if a user turns off JavaScript, that random content is lost. Google, MSN, and Yahoo will see that the content is changing often, and that may help your rankings (depending on your implementation).

Here’s how to put the random elements into your page, using PHP.

Step 1:
Create a text file called ‘myData.txt’. Open the file and put in your random elements, placing each random element on its own line, (whether text, images or html). Then place ‘myData.txt’ in the same directory as your page containing the PHP script.

Step 2:
Place the following PHP code into your page where you want the random element:
