Alpha/Numeric problem.

[Promextheus Xex]

I'm having a problem with numbers. I'm getting a number from an array that
seems to have a padded space at the beginning.

IE: " 5"

What I've done was $var = ltrim($var) which removes the space but with one
problem. Now I think PHP thinks it's a sting and not a number.

Then I try $var = settype($var, "integer") to see if it will become a
numeric for addition purposes.

Next problem... $var is now 0 and gettype($var) shows its and integer.

Why would it be 0 and not 5? Perhaps there's an obvious starring right at
me and I'm not seeing it?

Oops... I made a typo (not a mistake in my code):

"Then I try $var = settype($var, "integer") to see if it will become a "

should have been:

"Then I try settype($var, "integer") to see if it will become a "
^
(This is what I have actually coded and should have typed in my post.)

Usually you don't have to explictly set a type. Just use the variable
as-is (even if there's leading white space, it shouldn't matter), PHP
will automatically convert it when necessary.

$var = ' 5';
print $var+10;

outputs 15. If you still want to do an explicit typecast, just write

$var = (int)$var;

That's enough. There's need for ltrim() and settype() in this case.

There's definitely something wrong, if you get a 0. What version of PHP
do you use?

PHP has loose typing and can easily deal with that.

e.g.

$string1 = " 5";
$string2 = 2;
echo $string1+$strin g2;

//outputs 7

Your problem is elsewhere.
