Passing Array through a Function

[spishack]

Okay, here's my problem.

I am converting hexidecimal values using base_convert. Now, I have like 12 values to convert, each stored as a different variable.

I want to make a function to convert them, and I want to put them in an array first... then send them through the function, then grab them back from the array. I can't get this to work.

Something along the lines of:

$stuff = array('$hex1', '$hex2', '$hex3');

function convertHex($convert) {
$convert = base_convert($convert, 16, 10);
}

convertHex($stuff[]);

Obviously, this does not work. I'm not too good with arrays... help?

TIA

try this:

$stuff = array('$hex1', '$hex2', '$hex3');

function convertHex($convert) {
$converted = base_convert($convert, 16, 10);
return $converted;
}

$convertVals = convertHex($stuff);

The other post was correct in that you were forgetting to return your result, but unless I'm mistaken, base_convert format looks like:

string base_convert (string number, int frombase, int tobase);

So, if you want to convert every element of your array from hex to dec, we need to loop through it. Something like:

$stuff = array('$hex1', '$hex2', '$hex3');

function convertHex($convert) {
while(list($key, $hex) = each($convert)) {
$convert[$key] = base_convert($hex, 16, 10);
}
return $convert;
}

convertHex($stuff);

The while(list..each) loops through the array and gives back the key (each array element has a 'key' associated with it to distinguish it as unique in the array) and the actual value of that array element (to be held in $hex). Now, we just replace the value in the array of that key to the converted value and you get an array back with everything converted from hex. Hope that helps!
