You can use preg replace in this case    res   preg replace     0-9          Every 6 Months        res return 6 in this case   If want also to include decimal separator or thousand separator check this example    res   preg replace     0-9             123 099       res returns  123 099  in this case  Include period as decimal separator or thousand separator      0-9      Include coma as decimal separator or thousand separator      0-9      Include period and coma as decimal separator and thousand separator      0-9
