What are PHP variables?
PHP variables are identifiers used to represent a value. In other words, they are used to store information such as numbers, strings, arrays, and objects. Variables can be defined using the dollar symbol followed by the name of the variable.
In your PHP script, you will need to use the echo statement to output the information. You can use any type of information that can be converted into a string data type. For example, you can output numbers, strings, arrays, or objects.
Once you have Echoed the desired information, you will need to make sure that your server is configured to send the correct header information. This can be done by adding the following line of code to your .htaccess file:
AddType application/x-httpd-php .js
