In PHP, there are three types of arrays: Indexed arrays - Arrays with numeric index; Associative arrays - Arrays with named keys; Multidimensional arrays - Arrays containing one or more arrays The array_push() function inserts one or more elements to the end of an array.

So it is highly recommended that instead of using settings files, you pass the settings as an array directly to the constructor (explained later in this document). This array holds key/value pairs, where keys are the names of the form controls and values are the input data from the user.
