[SOLVED] adding of variables

[timmah1]

This code worked fine, but now it don't

 

Can anybody tell me what's wrong?

 

<?php
$val=substr($val,0);
$price = explode(",", $val);
$tmp = number_format($price[1], 2);
$total_price += $tmp;
echo $total_price;
?>

 

It use to work regardless if there was one or two values for price[1]

 

Thanks in advance

On the phone...

 

A: Foo Bar, Inc. car repair service. How can I help you?

B: Hi, my car is broken. How long time will it take for you to repair it and how much will it cost?

Most popular way to debug, echo variables out.  Here's your output, do you see what's going on here?

 

$val = 12345;
$val=substr($val,0);  //12345
$price = explode(",", $val);  //[0] => 12345
$tmp = number_format($price[1], 2); //0.00
$total_price += $tmp; //0
echo $total_price; //0
?>

 

Like Daniel is implying, we need more information.  What did you change?  What happens?  How did it used to work (example)?  etc...

Guess if Daniel would of happened to explain it that way, I would've understood what they meant, my apologies for not posting enough code.

 

<?php
while (list ($name,$val) = @each ($_POST['package_'])) {  
		  
$val=substr($val,0);
$price = explode(",", $val);
$tmp1 = $price[1];
$total_price += $tmp1;
}
echo $total_price;
?>

 

The price of $_POST['package_'] is the second value

I fixed it, naturally, it was my stupid mistake

 

$price[1] was formatted this way

$price1 = "$".number_format ($price, 2);

 

So obviously, it can't add with the dollar sign

 

Thanks
