Updated. The function did accept other characters. And how not is
possible to use de HANDLE_NUMERIC(), I make a loop and check for each
char.

Last patch works much more better, but there is still a problem.

the patch ignores leading spaces.

for example keys ' 10' and ' -10' are converted to integer 10 and -10.

Yes, correct. I've used not suitable function. Tony alerted me of a
correct function.

Looks like the simple solution is not very good.
As far as I understood the patch just convert any numeric string to
long.

It is not right way because:
1) it dose not make range check ("9999999999" is converted to
2147483647)
2) it dose not recognize negative values ("-10" is not converted to
string)
3) it ignores leading zero ("01" to 1)

For example, the reproduce code result is still not expected:

1
Array
(
   [10] => 3
   [1] => 2
   [01] => 4
)
KEY: int(10)
VAL: int(3)

KEY: int(1)
VAL: int(2)

KEY: string(2) "01"
VAL: int(4)
