ItвЂ™s a lot quicker and better to call a function by name than to rewrite the block of code that function represents over and over again.ДonвЂ™t worry about functions for now, though. A function is a block of code, usually with a name assigned to it, which you can call from your own code anytime you need that block. Technically, mysql_connect, mysql_error, and die are all examples of functions. So you can call mysql_error as part of your die statement to show what really happened. It makes the errors it ran into in trying to connect available through another command, mysql_error. Not only that, but mysql_connect sets up another function when it canвЂ™t connect. (See the box on Everybody Dies at Some Point for more detail on the die command.) ItвЂ™s dead on the server room floor, in search of a working database connection. Your users wonвЂ™t ever see the вЂњConnected to MySQL!вЂќ line because the script will have stopped running. So if mysql_connect returns false, and die runs, your script will exit. die prints out an error message, but it also вЂњdies.вЂќ In other words, it ends your script.

It basically says, try to connect (using mysql_connect), and if the result isnвЂ™t true (the or part of the code), then die. Not only is this script shorter, but it flips things around a bit. So whatвЂ™s really happening in your script is something like this: Д«ut that's a lot of typing, so PHP lets you shorten it to the following: But if mysql_connect canвЂ™t create that connection-for example, if your database isnвЂ™t running or youвЂ™ve got a bad host or username- mysql_connect returns a very different value: false. It then returns that connection to your PHP program, and makes available all the other PHP-to-MySQL commands youвЂ™ll learn about soon. When mysql_connect runs, it either creates or reuses an existing connection to your database.

In this case, die prints an error message that wonвЂ™t scare off your users.Д«ut before you can understand die, you have to know a little bit about the inner workings of mysql_connect. Think of die as saying, вЂњIf my code dies, then do something less nasty than tossing out an error code to my user. In fact, it is a bit nasty: you use die when something may go wrong in your script. Make sure you change, your-username, and your-password to the values for your own database.Д«ut what about the die bit? Sounds a little gruesome (like Lord of the Flies gruesome, not Twilight teen-angst gruesome). In your script, type the following lines: Error connecting to database: '. This script will be as simple as possible, because all you need it to do is connect to your database, USE the right database, and then run a sample SQL query to make sure things are working correctly. You need those same pieces of information to give PHP so it can connect: your database host, your username, and a password.ДЇire up your text editor and create a new script call it connect.php.

When you connected to your web serverвЂ™s database, you probably used a command like the followng: mysql -host=

This process is basically telling PHP to do what you did when you started up your MySQL command-line client ( MySQL on Mac OS X).

All that in one chapter? Yes indeed.ДЇirst, you have to tell your PHP script how to connect to a database. This script will take all the information from the forms youвЂ™ve built, add that information to a database, and then add one more form to let your users search for another user by name. Then, to put a cherry on top of your towering sundae of PHP and MySQL goodness, youвЂ™ll write another script. When youвЂ™re a PHP programmer you can go beyond the mysql command-line tool. In fact, youвЂ™re going to build a simple form that lets you enter SQL and run it against your MySQL database. You just need to learn a few new commands and how to deal with the problems that can come up when youвЂ™re working with a database. PHP isnвЂ™t like that though it comes ready to connect to MySQL from the moment you run the php command.Д®ven though youвЂ™ve only recently begun your journey to PHP mastery, youвЂ™re ready to use a database from your scripts.

With many programming languages, anytime you want to talk to a database, you have to download and install extra code, or install little plug-in models that give your programs support for talking to that database. Now that youвЂ™ve seen a bit of the power both of PHP and MySQL, itвЂ™s time to bring these two juggernauts together.
