New Comment:
I guess there's no way PHP will be ready for serious work with this
kind of attitude. Type 'int' in C is signed 32-bit on all POSIX
systems, and there had to be special work done to break the behaviour
of a purely numeric integer function like crc32(). If you realise the
brokeness, please update documentation, add a bug description section,
wich at least documents it. The same suggestion is valid for all
functions that substantially differ from documented behaviour on
different architectures.

Use dechex(crc32('10780')) to get string value, which is the same on
all architectures.
The integer value differs because of obvious reasons.

Description:
------------
crc32() in PHP returns an integer larger than 2G on a 64-bit platform;
It's documented, and applications rely on it, that it will return a
signed integer from the range [-2G .. 2G]. The major problem with
64-bit crc32() here is that databases can't store the value in a column
declared as INTEGER, thus braking compatibility.
Reproduce code:
---------------
echo crc32('10780');
Expected result:
----------------
-1171594808
Actual result:
--------------
3123372488
