Big Hex Numbers

[Anon]

I have made a php Blowfish class -- however I cannot get it to work as PHP chokes on large hex numbers eg: 0x3F84D5B5L

print $a = 0x12 == 18
print $a = 0x3F84D5B5L == 0
print $a = 0x3F84D == large dec number
print hexdec(0x3F84D5B5L) == 0

etc

Without this ability I cannot complete the class 🙁 Maybe that's why there isn't a PHP blowfish!

Any suggestions on how to get around this?
