For 2023 - we are now fully retired from IT training.
We have made many, many friends over 25 years of teaching about Python, Tcl, Perl, PHP, Lua, Java, C and C++ - and MySQL, Linux and Solaris/SunOS too. Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own risk.

Lisa and I (Graham) now live in what was our training centre in Melksham - happy to meet with former delegates here - but do check ahead before coming round. We are far from inactive - rather, enjoying the times that we are retired but still healthy enough in mind and body to be active!

I am also active in many other area and still look after a lot of web sites - you can find an index ((here))
Quickie on preg_match

Posted by Quaor (Quaor), 22 July 2003
Hi all. Have a very simple question for you - yes I'm a newbie, just can't get this right...
How do I check for the string www using preg_match?

Many thanks

Posted by admin (Graham Ellis), 22 July 2003
Here is a test using preg_match to see if a string entered by the user contains the letters "www" anywhere in it:

<form><input name=url></form>
Does a string contain "www"?<br>
if (preg_match("/www/",$_GET[url])) {

       print ("Yes");
} else {
       print ("No");

The test would differ if you were looking for the string www exactly, or looking only for strings starting with www.
