[SOLVED] Remove Characters From String

[TecTao]

I want to create part of an ID number that will have the first 4 characters of an administrators last name.  I will combine that new string with a random generated set up numbers.

 

For example an administrator with the last name smith creates a new entry the new member will have an ID number smit-4kjfsl46.  The smit being the first for characters of the last name.

 

I've read over the substr_replace or trim function but can't seem to find anything that will remove all characters except for the first for.

 

Any help or idea.  Thanks in advance.

You can get it using

substr($name, 0, 4);
