Function help

[bladewolf2010]

Hey,
I have a function that converts my money into gold, silver and copper. (code below) I was wondering if there is a way to make it so if there is 0 copper and\or silver it'd make it not show it. (IE: 200gold 300 silver 000copper make it look like this, 200gold 300 silver) Thanks for the help in advance

function gold_format($money)
{
$counter=strlen($money);
if ($counter <= 3)
{
$moneydone="
$money<img src='images/Copper.png'/>";
return $moneydone;
}
if ($counter <= 6)
{
$copper= substr($money, -3);
$silver= substr($money, 0, -3);
$moneydone="
$silver<img src='images/Silver.png'/>
$copper<img src='images/Copper.png'/>";
return $moneydone;
}
else
{
$copper= substr($money, -3);
$mid=($counter-6);
$silver= substr($money, $mid, -3);
$gold=substr($money, 0, $mid);
$moneydone="
$gold<img src='images/Gold.png'/>
$silver<img src='images/Silver.png'/>
$copper<img src='images/Copper.png'/>";
return $moneydone;
}
}

Use is_null

[bladewolf2010]

Could you explain how is_null is used?

You best bet for any questions about php functions is to go to PHP.net and search for the function.
Each description usually comes with details and plenty of examples for you to figure things out on your own.

Well I thought just by the name of the function it would be self explanatory is null or not!

is_null() how hard is it to use? Like any other function, really easy. is_null($var)...

[bladewolf2010]

Thanks for the advice, got it to do what I needed it to do using ltrim.

Kinda botch it fix isnt it?

Sounds like you couldnt get it to work so your just removing the output.

[Spudinski]

I don't even understand the damn function!

Why do you have gold, silver and bronze all using a single field?

I'm confused as to what is happening here and why you are splitting it 3 times.

For simplicity, if nothing else, use 3 fields!?

He's assuming three digits in the string, i.e. 100gold, and thus only collecting the values of them, i.e. 100.
Flawed in some ways, but it does work if the integer value is above 100 and below 999.

I know what you mean. But i don't know how to code except il give you a psuedo code.

If copper = "000" then
copper = nothing
else if silver = "000" then
silver = nothing
else if gold = "000" then
gold = nothing
end if

xD ? any help there :P
