I'm tyring to simplify the design of a web site which uses PHP, and hope someone can help me. Basically I want to store a number in a file on a web site, and display that number, or a variation of it, on a number of web pages. Let's say the parameter is "A", and is 10 ps. Three different web pages need to display this number, but in 3 different ways.
1) First page shows just A
2) Second page multiples A by 3
3) Third page multiples A by -2
So if A was 10
1) Page 1 should show 10
2) Page 2 should show 30
3) Page 3 should show -20.
If the value of A changes, I'd like to update the web site in one place, and not go around to every page updating them individually, as that will be error prone.
Is there a way to put the value of A in a text file, and use the value in different parts of the site? If so how?
Since there will actually be 15 or so parameters, A, B, C ..., is there a way I can put all 15 parameters in a file (perhaps one per line, or with white space between them), rather than have 15 different files?
If you look at this web page which is for an economimcal / low cost vector network analyzer kit,
http://www.vnacalibration.co.uk/support/85033/Rohde+Schwarz/
you can see the numeric values in the form used by Rohde & Schwarz for their vector network analyzers, whereas in this page which is a bit longer, under the section "Standard Definitions",
http://www.vnacalibration.co.uk/support/85033/HP/
one has basicaly the same parameters, but expressed in a different way. Another make of vector network analyzer wants the parameters in a different way.
Any thoughts?
