WhyAmIPoor

$xml= simplexml_load_file("https://api.eveonline.com/char/CharacterSheet.xml.aspx?userID=$f23&apiKey=$f24&characterID=$f26");
$isknoformat=$xml->result->balance;
$isk = number_format($isknoformat);
For some reason its not working. $isknoformat gets the right data from the xmlsheet for example 57563524.67
But when i try to echo $isk I get nothing. echo $isknoformat gives 57563524.67
I have no idea at all why it isnt working.
Help?

For ISK 57563523.67 I'd guess the answer lies in the function 'number_format'. I'm no PHP guy, but isknoformat is supposedly a string, wheras the function will need a number parameter?!?

$isknoformat=$xml->result->balance;
returns an object, which cannot be formated by number_format. The automatical casting into a string is only done on echo calls and similar. so you should try something like that
$isknoformat = (string) $xml->result->balance;
$isk = number_format($isknoformat);

Much love that was it, $isknoformat was a string not a integer adding intval() worked
$isk = number_format(intval($isknoformat));

For some reason, PHP calls the __toString method, whenever you cast an object to a primitive. So WhyAmIPoors code will work, because calling
$isk = intval($xml->isk);
is internally processed as
$isk = intval( strval($xml->isk) );
Works for all type conversions, including (float) and (bool). That's maybe a little weird but at least it makes things work for non professionals  .

I would suggest suing floatval() since a lot of times, the numbers in EVE are bigger than what 32bit integers allow. Also, the ISK amount is a float, not integer value.

It's no float either. If possible, it should be treated as a currency datatype, as floats are not guaranteed to be accurate. See the big red warning for PHP floats (which isn't PHP-specific but true for all IEEE floating point number implemetations).
I just recently had to help a work mate who was going to lose her mind, because numbers didn't add up correctly. The above mentioned limitation caused the problem.

Unfortunatelly, it IS float :/
Why? Ask EVE devs...

In EVE's DB - yes (i.e. eventually can't get a wallet back to 0 ISK, it will always reamin 0.01 ISK).
But not in the API data. It's a string there and the numerical datatype you convert it to. So, be nice and make it (the equivalent of) Currency and you're good on your side.

$xml= simplexml_load_file("https://api.eveonline.com/char/CharacterSheet.xml.aspx?userID=$f23&apiKey=$f24&characterID=$f26");
$isknoformat=(float)$xml->result->balance;
$isk = number_format($isknoformat);
That should work.
