I would like to know if this is possible with PHP programming: You send a Text Message from a Cell Phone to a special number or a domain name. Then this PHP script can receive all information about the Text Messages and put them in a database which you can read. That script should save the Cell Phone number and actual content into the Database. Then you can log into your admin area and review all received text messages. Thanks for any suggestion.
Some of the wording you used is confusing, but it is possible to allow people to send text messages through your website, and record who they are sending it to, and what it says.
If the cell phone is capable of sending e-mail (most are) then that would be fairly simple to program in php.

But it looks like it should work.
