Searching for the optimal calculation method Finding the best way to calculate arrays is really not going to come out. I have two arrays, respectively: PHP Code $arr 1=array ( array ( ' id ' =>1, ' pos ' =>1 ), array ( ' id ' =>2, ' pos ' =>2 ), array ( ' id ' =>3, ' pos ' =>3 ), array (

N_OR_S is a number, a string with a hexadecimal value of N is returned. Here, N is a longlong (BIGINT) number. This is equivalent to CONV (N, 10, 16 ). If N_OR_S is a string, the return value is a hexadecimal string of N_OR_S. Each character in N_OR_S is converted to two hexadecimal numbers.
