Turns out PHP standard crc32 method is non-standard (while crc32b is).
Here is how to implement it in Python:
crc = 0xffffffff
for x in a:
crc ^= x << 24;
for k in range(8):
crc = (crc << 1) ^ 0x04c11db7 if crc & 0x80000000 else crc << 1
crc = ~crc
crc &= 0xffffffff
# Convert from big endian to little endian:
return int.from_bytes(crc.to_bytes(4, 'big'), 'little')

A month ago, I wanted to automate queries to a website that is using the PHPSESSID cookie to keep track of sessions. I struggled a lot and couldn't find any documentation covering the behaviour I was observing. But yesterday I finally found a solution !
