For 2023 (and 2024 ...) - 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 Our training notes are now very much out of date, but due to upward compatability most of our examples remain operational and even relevant ad you are welcome to make us if them "as seen" and at your own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))
Adding spaces to a string

Posted by Chris_Isaac (Chris Isaac), 17 September 2003
I'm sure theres an easy way to do this, but I'm stuck.  What I want to be able to do is format a string of numbers, eg, 01234567890 into smaller chunks like 01234 567890.  I've tried Preg_split, amongst a few others but have been unable to get it to work, I looked at explode but they all seem to want a seperator which insn't there.  

Any help/pointers appreciated.

$number = "01225708225";
$area = substr($number,0,5);
$num = substr($number,5);
print ("$area $num");

gave me 01225  708225.

Unsure where you want to split; I'm thinking it's a phone number, and if that's the case you need it to be one character earlier in certain circumstances.   The evolution of the phone system hasn't made it easy in this country
