This project contains php scripts which can be accessed world wide on a PHP server, for the inclusion in front or back end website development, allowing for the convenient representation and calculation of common integer sequences, including

- Factorials
- Prime numbers
- Horadam numbers
- Polygonal numbers
- Pascal numbers
- Hofstadter numbers

Developed and maintained by Tyler R. Drury,

Use
---

[](#use)

For front-end use in browsers, please use JavaScript to make AJAX requests.

*note*-for convenience jQuery is used in the example.

```
$.get(
    '...intSeq\\fibonnacci.php?N=20',
    function(obj){console.log(obj.toString());}
);

```

or alternately if a constant series is required when the webpage is served, replacing the html pre code tags with script tags.

```

var f = ;

console.log(f);

```

For back-end developers, the most current stable Source Code can be found here, or for developers whom wish to contribute, through the GitHub repo [here](https://github.com/vigilance91/integerSequences-php).

After installing the integerSequence directory on your server, scripts may access the namespace and its contents in the following manner.

```
require_once 'integerSequence.php';

use integerSequence\Horadam as Horadam;
use integerSequence\Fibonacci as fib;
use integerSequence\getPrimes;

$p = getPrimes(1000) //calculate all primes up to 1000
$h = Horadam(2,3,1,2);    //unnamed Horadam sequence
$s = $h->series(20);
$f = fib::series(20);

echo json_encode(
    'primes'=>$p,
    'horadam'=>$s,
    'fib'=>$f
);

```

This script will return a JSON encoded object containing all prime numbers up to 1000, the first 20 elements of an arbitrary, unnamed Horadam sequence, along with the first 20 elements of the Fibonacci sequence.
