$item_amount_in_store = 223;
$update_amount = 7;
$update_item_amount_in_store += $update_amount;
$update_amoint_in_store is now 227;
Why? That should be 230!

Because you're using $item_amount_in_store and $update_item_amount_in_store as
if PHP should know you mean the same thing.

Hi,
Shouldn't it be:
$item_amount_in_store = 223;
$update_amount = 7;
$item_amount_in_store += $update_amount;
$update_amoint_in_store is now 227;
The 3rd line seems wrong as you didn't use the same variable.

Error in my last post This is corrected:
$item_amount_in_store = 223;
$update_amount = 7;
$item_amount_in_Store += $update_amount;
It show the result = 227 and not 230. Why is this happen?

Something else is going on to give you 227, but variable names are case
sensitive which is why you're not getting what you expect.
<?php
$item_amount_in_store = 223;
$update_amount = 7;
$item_amount_in_Store += $update_amount;
var_dump($item_amount_in_store);
var_dump($item_amount_in_Store);
?>
Output:
int(223)
int(7)

You should give a complete programm so we can run exactly
the same you do, like this:
<?php
$item_amount_in_store = 223;
print ("$item_amount_in_store");
$update_amount = 7;
$item_amount_in_store += $update_amount;
print (" + $update_amount = $item_amount_in_store ");
?>
which gives this result:
223 + 7 = 230
--- End Message ---

variables are case-sensitive.
$item_amount_in_store is different from
$item_amount_in_Store
1st variable contains all lowercase characters, while the 2nd one contains
"S" uppercase character.
happy coding

Hi Karl,
i dont know what you want to do. But i can say: The
$item_amount_in_store variable is not the same to $item_amount_in_Store
(case sensitive). It work for me...

First of all, I don't know why you would use the print *function* when
you can also use the echo language construct (better and faster). But
that's not that important; it's not bad to use it, just imo a bit ugly
(pet peeve ;)).
But more importantly:
"$variable" is completely and utterly useless. You're basically creating
a string, interpolating a variable in it, and adding no more content.
This is effectively the same as saying:
print("".$var."")
Does that look right to you? To me it looks... wrong...
Why not just a simple:
echo $var;
or
print($var) if you really must.
And if you really really must cast the variable to a string, you can
always use the explicit:
(string) $var
$update_amount = 7;
$item_amount_in_store += $update_amount;
print (" + $update_amount = $item_amount_in_store ");
?>
which gives this result:
223 + 7 = 230

read and learn http://de2.php.net/manual/en/function.print.php
print is not actually a real function (it is a language construct)

1) You did not answer the question, nor giving any related information.
2) This was debug-output. I see not point in optimizing.
3) print is language construct, just as is echo
4) the argument to print is converted to string anyways, so ...
5) the quotes around a single variable allows fast adding helping text while
debugging; so it was on purpose
You are not the only one that has a coding style for a reason.
So back to topic: I guess the case-sensitive variables were the most helpfull
hint for the
thread-starter?
If not please send a complete example of your code.
