Before creating a php application or website you will first need to check if PHP is supported by your Web Hosting Provider. In other words your webhost will need to have PHP installed on the webserver were your site is housed.

It is often necessary to arrange the elements in an array in numerical order from highest to lowest values (descending order) or vice versa (ascending order). If the array contains string values, alphabetical order may be needed. Sorting a one-dimensional arrays is quite easy.

Let's get started. The first thing to do is connect to the database.The function to connect to MySQL is called mysql_connect. This function returns a resource which is a pointer to the database connection. It's also called a database handle, and we'll use it in later functions. Don't forget to replace your connection details.

Arrays can most easily be described as an ordered list of elements. You can access the individual elements by referring to their index position within the array. The position is either specified numerically or by name. An array with a numeric index is commonly called an indexed array while one that has named positions is called an associative array. In PHP, all arrays are associative, but you can still use a numeric index to access them

The If Statement is a way to make decisions based upon the result of a condition. For example, you might have a script that checks if boolean value is true or false, if variable contains number or string value, if an object is empty or populated, etc. The condition can be anything you choose, and you can combine conditions together to make for actions that are more complicated.
