A Handy alphabet class :) - Abu Ashraf Masnun

Another funny class with no serious use. This is a class I wrote to determine the numerical positions of letters in the English alphabet.

How to use ?

<?php
include('alphabet.php');
$a = new alphabet(); // construct the alphabet object
echo $a->getNum('z'); // outputs 26
echo $a->getChar(3); // outputs 'c'
?>

<?php

include('alphabet.php');

$a = new alphabet(); // construct the alphabet object

echo $a->getNum('z'); // outputs 26

echo $a->getChar(3); // outputs 'c'

As you can see, using the getNum() method, you can feed a letter and get the serial number or numerical position of that letter. Again in the same way, use the getChar() method to input a number and get the character/letter in that position.

I use it very often while breaking alphabet related codes.

Source Codes:

<?php
// filename: alphabet.php
// Author: maSnun

class alphabet {
public $num, $alpha,$dict_1,$dict_2;
function __construct() {
$this->num = array(); // placeholder for 1 to 26
$this->alpha = array(); // placeholder for a to z

for($i=1;$i<27;$i++) { $this->num[]= $i; } // dynamically store 1 to 26 in the array
for($i='a';$i<'z';$i++) { $this->alpha[]= $i; } // dynamically store a to y in the array
$this->alpha[] = 'z'; // manually add z to the array
$this->dict_1 = array_combine($this->num,$this->alpha); // combine them to form a dictionary
$this->dict_2 = array_combine($this->alpha,$this->num); // combine them to form a dictionary
}

function getNum($char) { return $this->dict_2[$char]; }
function getChar($n) { return $this->dict_1[$n]; }


}

?>

<?php

// filename: alphabet.php

// Author: maSnun

class alphabet {

public $num, $alpha,$dict_1,$dict_2;

function __construct() {

$this->num = array(); // placeholder for 1 to 26

$this->alpha = array(); // placeholder for a to z

for($i=1;$i<27;$i++) { $this->num[]= $i; } // dynamically store 1 to 26 in the array

for($i='a';$i<'z';$i++) { $this->alpha[]= $i; } // dynamically store a to y in the array

$this->alpha[] = 'z'; // manually add z to the array

$this->dict_1 = array_combine($this->num,$this->alpha); // combine them to form a dictionary

$this->dict_2 = array_combine($this->alpha,$this->num); // combine them to form a dictionary

}

function getNum($char) { return $this->dict_2[$char]; }

function getChar($n) { return $this->dict_1[$n]; }

}
