Description:
------------
The manual says that as of PHP 5.2.12, the range for the base argument to gmp_strval() was extended from 2 to 36, to 2 to 62 and -2 to -36.  However, in my tests only 2 to 26 worked.

Reproduce code:
---------------
foreach (array_merge(range(-2, -36), range(2, 62)) as $num) {
	if (@gmp_strval(gmp_init(62), $num)) echo "Base $num: GOOD\n";
	else echo "Base $num: BAD\n";
}

Expected result:
----------------
gmp_strval() should return a value for all bases in specified range.

Actual result:
--------------
gmp_strval() fails to return a value and gives warning, "Bad base for conversion", for bases -2 to -36 and 27 to 62.

Sorry, s/26/36/ in second sentence and s/27/37/ in last sentence.

What version of GMP is PHP compiled against? For the extended range to be possible, you must be using GMP 4.2 or greater

I have GMP 4.3.2.

Also, I just tested this on another system with PHP 5.3.1 linked against GMP 4.3.1 and got the same result.

This bug has been fixed in the documentation's XML sources. Since the
online and downloadable versions of the documentation need some time
to get updated, we would like to ask you to be a bit patient.

Thank you for the report, and for helping us make our documentation better.

Seems like GMP changes never was merged to 5.3.1 (in 5.2.12 it was removed [1]), but they are available according to the source in 5.3.2 [2][3].

I've updated the relevant ChangeLog information for both gmp_init() and gmp_strval() to reflect this change.
