Here we have to discuss about the thing how to convert automatically a number as string(word) using PHP. We already discuss the things in conversion of current webpage as MS-Word document and PDF file. Similar to this conversion we going to convert a number as word(string). It is also used in the application projects. Most of the billing system required automatically generate the total amount in word after entering the total amount. Similar to this most of webpage need to convert the entering number into word(string).
There is three cases in conversion of word. We able to convert the number as word(string) in following cases.
- Upper Case
- Lower Case
- Camel Case
syntax
[code type= php]
strtoupper(convertNumber($num))
strtolower(convertNumber($num))
ucwords(convertNumber($num))
[/code]
Let’s see the simple example”
