The PHP language is a server-side scripting language that’s usually embedded with the HTML of a internet page. Upon a page request, the PHP script inside the HTML page is executed by the internet server and substituted with HTML elements prior to the page is displayed by the browser to the user. PHP has numerous libraries and much more are developed as time goes by. All of these libraries are available in numerous inexpensive PHP hosting resources and supply for a fast entry to databases management systems and is thus an ideal tool that’s used in application logic development. PHP also includes library functions that provide for execution of SQL statements. In addition, these functions also help within the management of database queries, error handling and within the data control between the PHP engine and the databases resource. This means that the server that hosts the PHP engine will need to host the SQL engine too or have access to it. Cheap PHP hosting destinations are available that offer these services.

There are many PHP scripting techniques that are used to query a MySQL server and get the HTML results displayed about the web browser. Generally, connecting towards the server with PHP involves a number of steps. The very first step involves opening the databases connection using a script like the following;

$connection = mysql_connect (“localhost”,”David”,”Mike”);

Next is to choose the specific databases we want to query. Again you use a script from the sort; mysql_select_db (‘Microsoft’, $connection). At this juncture you’ve a connection towards the database and you are able to now manipulate data. Of course, at to this point, we have assumed that your web server has both the SQL and PHP scripting engines installed. In most cases though, you do not need to worry about this; even inexpensive PHP hosting and MySQL servers provide support to these engines since they are the most widely utilized. It’s usually good to confirm very first with your service provider prior to deploying such scripts to avoid disappointments later.

Back to our ‘Microsoft’ databases, we then need to run a query on the Microsoft databases. For example, this query could be a listing of the employees within the organization or their products. You can then query a specific row and have the results printed out. To ensure that the results are formatted correctly, print a carriage return utilizing something like ‘print “\n”’. Remember that we are utilizing PHP and thus you will have to have the appropriate tags in place when doing the querying. This is an example of the power that PHP and SQL provide in databases entry. There are many cheap PHP hosting servers about the internet that you can use to try this out with. You will be amazed at the power of these web tools.
