substr / strtoupper help please

[Piercezz]

Hello,

 

A not so experienced PHP-user here. For my school assignment, I have to make the following:

 

"Stolwijkstraat 8" has to be shortened into SW with use of SUBSTR and STRTOUPPER. 

 

My question:

1. How can I be able to use SUBSTR and STRTOUPPER in the same line?

2. How can I be able to remove everything in the line ''Stolwijkstraat 8", on behalf of ''S'' and ''w''?

 

A quick response would be greatly appreciated.

 

Kind regards.

Try something and if you have trouble we'll help. We won't do it for you though. Start with the manual.

I'll give you this much http://php.net/manual/en/function.substr.php and you can nest functions like this:

$myvar=strtoupper(substr(GUESS WHAT GOES HERE));

Freak Dr.

 

First of all thanks for the quick response, second of all, ofcourse I have tried and came here as a last resort. Still trying tho (:

 

I am really struggling with the fact of getting both substr and strtoupper in one line tho.

 

I've got;

 

echo substr($myvar,#,#); as where # is a number that i'm trying out atm

I already figured it out. Thanks anyway.
