PHP string and byte array conversion class example_PHP tutorial

The article provides you with an example of conversion between PHP string and byte array. I hope the article will be helpful to all students.

The code is as follows

Copy code

/** * Byte array and string conversion class */ class Bytes {   /** ​   * Convert a String to a byte array ​   * @param $str The string to be converted ​   * @param $bytes target byte array ​   * @author Zikie ​   */ Public static function getBytes($string) {           $bytes = array(); for($i = 0; $i < strlen($string); $i++){                 $bytes[] = ord($string[$i]);           }           return $bytes; }   /**       * Convert byte array to String type data       * @param $bytes byte array       * @param $str target string       * @return a String type data       */ Public static function toStr($bytes) {           $str = ''; foreach($bytes as $ch) {                  $str .= chr($ch);           }               return $str; }   /** ​   * Convert an int to a byte array ​   * @param $byt target byte array ​   * @param $val The string to be converted ​   * ​   */ Public static function integerToBytes($val) {            $byt = array();           $byt[0] = ($val & 0xff); $byt[1] = ($val >> 8 & 0xff); $byt[2] = ($val >> 16 & 0xff); $byt[3] = ($val >> 24 & 0xff);           return $byt; }   /**       * Read an Integer type data from the specified position in the byte array       * @param $bytes byte array       * @param $position specified starting position       * @return an Integer type data       */ Public static function bytesToInteger($bytes, $position) { $val = 0;           $val = $bytes[$position + 3] & 0xff; $val <<= 8;           $val |= $bytes[$position + 2] & 0xff; $val <<= 8;           $val |= $bytes[$position + 1] & 0xff; $val <<= 8;           $val |= $bytes[$position] & 0xff;          return $val; }   /** ​   * Convert a short string to a byte array ​   * @param $byt target byte array ​   * @param $val The string to be converted ​   * ​   */ Public static function shortToBytes($val) {            $byt = array();           $byt[0] = ($val & 0xff); $byt[1] = ($val >> 8 & 0xff);           return $byt; }   /**       * Read a Short type data from the specified position in the byte array.       * @param $bytes byte array       * @param $position specified starting position       * @return a Short type data       */ Public static function bytesToShort($bytes, $position) { $val = 0;           $val = $bytes[$position + 1] & 0xFF; $val = $val << 8;           $val |= $bytes[$position] & 0xFF;          return $val; } } ?>
