PHP to reverse Product Reference

[AndyBorrett]

I realise that this must sound like an odd thing to do but I want to display my none Actinic generated Product Reference in reverse order on the web page.

EG Real Product Reference = ABC1234
Display Product Reference = 4321CBA

I realise I need to put this in a PHP Block but have had no luck trying to modify any of the example in the AUG or Forum

Check out http://php.net/manual/en/function.strrev.php

echo strrev("Hello world!"); // outputs "!dlrow olleH"

Thanks for that Jont. Have bookmarked the site for future reference

For any future searchers here is the final code.

If I ever work out how to keep the first three letters the same and just reverse the last four digits I will post back.

<actinic:block php="true" type="PriceList" >
	     echo strrev("<actinic:variable name="ProductReference" />");
     </actinic:block>

Here you go:

<actinic:block php="true">
 $ref = '<actinic:variable name="ProductReference" encoding="perl" selectable="false" />';
 echo substr($ref, 0, 3) . strrev(substr($ref, 3));
</actinic:block>

Note that I removed the type="PriceList" bit of code as it seems erronous and redundant.

Thanks as ever Norman -code works perfectly.

$ref = '<actinic:variable name="ProductReference" encoding="perl" selectable="false" />';

Would I be right in thinking that $ref is a variable you have created and loaded the Product Reference into it.

echo substr($ref, 0, 3) . strrev(substr($ref, 3));

echo sends what is following it to the page
The first substr starts as position 0 and returns 3 characters
The second substr starts at position 3 and returns the rest of the characters and strrev reverses this part.

Is that correct in simple terms?

[NormanRouxel]

Yes. That's exactly what it does.
