#### 介绍
用php实现16进制/ASCII码的crc16的各种模式校验和

#### 使用说明

```
$a = "112233445566778899AABBCCDDEEFF11";
 
// CRC-16/IBM
printf("%x\n", $this->crc16($a,"hex", 0x8005, 0, 0, true, true));
 
// CRC-16/MAXIM
printf("%x\n", $this->crc16($a,"hex", 0x8005, 0, 0xffff, true, true));
 
// CRC-16/USB
printf("%x\n", $this->crc16($a,"hex", 0x8005, 0xffff, 0xffff, true, true));
 
// CRC-16/MODBUS
printf("%x\n", $this->crc16($a,"hex", 0x8005, 0xffff, 0, true, true));
 
// CRC-16/CCITT
printf("%x\n", $this->crc16($a,"hex", 0x1021, 0, 0, true, true));
 
// CRC-16/CCITT-FALSE
printf("%x\n", $this->crc16($a,"hex", 0x1021, 0xffff, 0, false, false));
 
// CRC-16/X25
printf("%x\n", $this->crc16($a,"hex", 0x1021, 0xffff, 0xffff, true, true));
 
// CRC-16/XMODEM
printf("%x\n", $this->crc16($a,"hex", 0x1021, 0, 0, false, false));
 
// CRC-16/DNP
printf("%x\n", $this->crc16($a,"hex", 0x3d65, 0, 0xffff, true, true));
