Question: I receive definitions of words via json. Sometimes I receive stuff like this:

> 
> inclusa1.
> 
> 
> 

(the number can also be 2, 3, and so on). How can I automatically detect (and remove) numeric characters that are appended to words?

Eg: This is acceptable:

> 
> people that live in 1 house.
> 
> 
> 

Eg: This is not acceptable:

> 
> people1.
> 
> 
>

Answer: 
`preg_replace('/(?<=[a-zA-Z])[0-9]/', '', $string);`

This just removes any numeric characters preceded by an alpha.
```
preg_replace('/(\b[A-Z]+)([0-9]+)/i', '$1', $string);

```
