Character Recognition

Recommended Posts

Here's what I'm trying to do;
I have a form that includes a large input box where you can copy and paste email messages.  What i'm WANTING to do is, when a user pastes the email into the input box, PHP will find character sequences like 555-2484 as ###-#### and know it's a phone number and paste that phone number in the "Phone" field.  More importatnly, I'm looking to extract container numbers out of the email which are always L=Letter N=Number: LLLLNNNNNNN

Any pointing in the right direction would be appreciated.

You need to look into PHP regular expressions.
