String manipulation on a variable

[denhamd2]

Hi,

Hoping someone can help...

I have a variable $var which contains "order" then a 3 digit number followed by "_q". This is within a repeat loop.
So examples of variable values might be:
order956_q, order123_q or order333_q, etc...

Basically what I need is if the variable begins with order, has 3 digits after, and end in _q then change the variable value to "Quantity". N.B. It must begin with "order".

Would anyone know any code that would do this?

if(preg_match('/^order[0-9]{3}\_q$/', $var)) {
  $var='Quantity:';
}

Thanks, that brilliant. If you could just help me on one last final thing...

I'm also looking to do something with a 2nd variable called $rate
An example of a value of rate is
Rate_order956_q

Could you possibly tell me how I'd just get rid of the orderxxx_q, ie in the above aget rid of order956_q?

Read the link I provided (and the links provided therein) and see if you can work it out for yourself. It's really not very different and you'll feel a whole lot better knowing you figured it out for yourself 🙂
