String Length

[Brianfree]

Hi, how do i convert a string with less than 5 chars to a string that has 5 chars with leading zeros?

ie

1234 converts to 01234
300 converts to 00300
12 converts to 00012
51284 stays the same

Etc.

Many thanks,

Brian

Cool!!! Many thanks!!

I am also trying to validate numberplates i.e

BN06OBE

How can i check if they are valid numberplates or not (as in correct format)?

Many thanks,

Brian

Hi

Not sure how British numberplates are formatted, but I would definitely use a regular expression. Based on your example :

if ([url=http://php.net/preg-match/]preg_match[/url]('/^[[:alpha:]]{2}[[:digit:]]{2}[[:alpha:]]{3}$/',$string)) echo 'OK';

There are a number of formats for britch number plated depending on the age of the car

examples are:

X123ABC
ABC123X
AB09ABC

& realy early examples are either 1-3 numbers followed by 1-3 letters or 1-3 letters followed by 1-3 numbers (I think)

I believe that totaly custome priovate plates are also possible if you have enough £

Yes, a 1 might stand in for I , or zero for O e.g.
J0HN (might not actualy be avaiable but you get the picture)
You could look on the DVLA (Driver Vehicle Licensing Authrority) at

http://www.dvla.gov.uk/

might have some usefull stuff.
