can't quite suss this

[none]

howdy all

I have a script thats throwing an error

basically $offset is a number i.e. 10, 20, 30 etc. and I want to get
the first digit of this number as it increases and add one to the
result and compare it. so if its 30, i want to get the '3' and add 1
to make it '4' and see if it matches a number. this is what i used but
i get an error

} elseif ($pages = intval($offset{ 0})++1) {

any direction would be greatly appreciated

thanks

try:
$pages = intval(substr($ offset,0,1)) + 1

did you mean "=="?


if ($pages == ((int)($offset/10))+1) /* do something */


Even though PHP is (almost) a typeless I try not to mix strings and
numbers whenever possible.

Do I see a = where == was meant ? Tip I read somewhere to prevent these
easy-to-miss mistakes at least when literal constants are in play:

If you need to evaluate if ($a==10) php won't complain when you type ($a=10)
(evaluates to True).
But if you use if (10==$a) omitting the = will surely generate an error.
