Variables As Keys In An Array | Possible?

[PHliP]

Hi all

 

After giving this one hours of thought and tedious trial, I saw myself obliged to join and ask here...

 

I made this function to look up the price from a $product.

I have an include on pages where I need the prices in the variables like the 3 first ones in the example.

 

The problem is that my function is only working when I hardcode prices as keys.

I tried all sorts of methods to get access to what's in the vars from within the function, but I'm starting to fear this is not possible and I can't use this way?

 

OTOH, it doesn't seem like keys have to be numbers, so I hope there is something I'm not getting...

 

$kofferprijs_Disco = 6.5;
$kofferprijs_Hawaii = 8;
$kofferprijs_Pirates = 7;

function priceLookup($product){
$pricelist = array(
$GLOBALS['kofferprijs_Disco'] => 'DISCOFEEST',
$GLOBALS['kofferprijs_Hawaii'] => 'HAWAI/TROPICAL',
$GLOBALS['kofferprijs_Pirates'] => 'PIRATES',
);

if (in_array($product, $pricelist)) {
$price = array_search( $product, $pricelist );
return $price;
}
}

$productPrice = priceLookup('PIRATES'); // should give me '7'

 

Tried every variation know to man...

$kofferprijs_Pirates

$$kofferprijs_Pirates

${$kofferprijs_Pirates}

$$GLOBALS['kofferprijs_Pirates']

${$GLOBALS['kofferprijs_Pirates']}

...

 

Thanks for any help! :-)

The problem is not so much about variable keys, or about using variable variables, or about trying to use floats as array keys, or about $pricelist being backwards, or about magic strings like "PIRATES", but more about all those things together.

$prices = array(
"DISCOFEEST" => 6.5,
"HAWAI/TROPICAL" => 8,
"PIRATES" => 7
);

$productPrice = $prices["PIRATES"];

Why can't you do it that way?

[PHliP]

Because that's the hardcoded way.

 

I want those prices in variables, in an easy accesible file for sitewide changing.

 

But I will try what you suggested with variables again...

 

From an example I looked up, I was supposing the "key" was the left side and often seemed numerical, therefore I started out that way.

 

Maybe not needing a function like this, will help it. Thanks

If you want an easily accessible file suitable for a PHP developer to change then just stick the array in a file and include the file. If you want a file that's editable for non-PHP developers then a file format like INI or XML.

 

Even better would be to switch to a database.

[PHliP]

Not up to database making yet. I'd rather make them a FileMaker (database) solution that will tidily upload that central file if it's too dangerous for them

 

It seems to be working great at first glance.

So I was just looking too deep into it and it was much simpler...

 

TYVM for the hints
