[SOLVED] $String help!

[dt_gry]

I am trying to store the last 4 digits of the credit card number that my customers use on my website. the field is set to 16 char. how would I store the last four digits into a $String_Var?

 

Thanks

Use substr to get the last 4 digits of the number

 

$ccnumb = '1234567898765432';

echo substr($ccnumb, -4);
