Can PHP alter a PHP file?
What I am wondering is. I have a PHP file all it has in it is just one variable and variable content. My question would be could I pull this variable content into a PHP read function then preg_match it to alter the PHP variables content.
The reason its just a variable on its own is the variable is the current VAT rate. I understand the alternative would be to use a text file but that would mean altering the sites content on several pages if it can be done this way I'd rather give it a go.
Thanks in advance

Not sure what you are trying to do...
How is the varible stored? As a numeric value, or as a text in Php?
If a text, use $strg = file_get_contents("filename");
Alter the string in it, then _put_contents("fielname", $strg);
Otherwise, it would be cleverer to put that variable as a constant:
define ("VAT", 17.5);
into an "include" file.
And use VAT in all your calls
==> echo "VAT charge: " .VAT;
