[RESOLVED] Value of Numerical chars in strings

[freedmania]

Is there a function for getting the numerical value of a string of numerals?

Say I have $str = "123". Is there some function zot() such that 123 = zot($str), or 167 = 44 + zot($str), or whatever??

I've searched the Manual for strings, numbers, numericals, numerics, and numerous variations of same.

Any hints would be deeply appreciated.

Thanks,

Well because php is a nice chap you don't really need to, but if it's necessary you can do a few things

$num = (int)$numString;  // this is casting to an int

$num = intval($numString);  // this is using a function to convert to an int

$num = 1 + $numString;    // this will give you what you were expecting

Yeah; I thought about that, and the thinking pointed me in the direction you specified. Your certainty trumped my growing agitation. Thanks for that.

The thing about 'niceness' is that it leaves much unsaid - sometimes, way too much. I'd made some other error. I never found it, because I wiped out all the code surrounding it and did it again, and it worked that time. But, since PHP could unobtrusively perform arithmetic on string numerals, I couldn't tell where my problem was.

That's why I'm so cranky. It's for the good of all mankind.

Thanks again.
