[SOLVED] Add text to string at a certain position

[mayfair]

Hello Guys

 

I have a string which contains a date formatted to look, for example, like: Thursday, 13/09/09

 

This is used throughout my site in various places and works great, however I now need to integrate this with an older ordering system which only accepts dates in the format of dd/mm/yyyy. I can strip the day of the week by using substr($delivery_date, - which gives me the equivalent of 13/09/09, however the year needs to be in 4-digit format and I can't seem to find a function that will allow me to add '20' to the beginning of the year. Using str_replace obviously overwrites the end portion of the date instead of adding to it, is there a simple workaround for this?

 

The date will always remain a fixed length of 8 characters which should be in my favour. Any help would be greatly appreciated.

$delivery_date = preg_replace('~(.*?)/([0-9]{2})$~', '$120$2', $delivery_date);

Is this all that is in the string?

Yes, after it has been trimmed the string contains exactly 8 characters like: 17/09/09

 

$delivery_date = preg_replace('~(.*?)/([0-9]{2})$~', '$120$2', $delivery_date);

 

Sorry Garethp, this didn't seem to work. When I ran it on: '27/10/09', I got: '009'

Sorry, forgot to add the start anchor

 

$delivery_date = preg_replace('~^(.*?)/([0-9]{2})$~', '$120$2', $delivery_date);

Damnit, I also forgot a slash in the replacement

 

$delivery_date = preg_replace('~^(.*?)/([0-9]{2})$~', '$1/20$2', $delivery_date);

Yep, that's cracked it.

 

Thank you!
