CRC32 is prone to conflicts. what should I do?

CRC32, which is prone to conflicts. the birthday paradox is not a test code. it is easy to calculate a pair of PHPcodedefine ('R', 1e5); $ _ CRC32 = array (); for ($ I = 0; ++ $ I) {$ tmp = sprintf ('% X', crc32 ($ I) CRC32, which is easy to conflict
The birthday paradox is not a lie

With the test code, it is easy to calculate a pair

PHP code

  Define ('R', 1e5); $ _ CRC32 = array (); for ($ I = 0; ++ $ I) {$ tmp = sprintf ('% X', crc32 ($ I); if (isset ($ _ CRC32 [$ tmp]) {echo "{$ _ CRC32 [$ tmp] }#{$ I} \ n"; break;} if ($ I
