random qr code generator

Many systems now register, log in or publish information modules are added to the random code function, is to avoid automatic registration program or the use of automatic publishing programs. The verification code is actually randomly select some characters to display in the form of a picture on the page, if you want to submit the operation of the same time you

Phpshuffle () random sorting code for arrays. The shuffle () function sorts the elements in the array in random order. If yes, TRUE is returned. otherwise, FALSE is returned. Note: This function assigns a new key name to the cell in the array. This shuffle () function sorts the elements in the array in random order.

integer as a random number and then plans the 32-bit pseudo-random number to [0,1], initializes the drand48 () with the function srand48, initializes the high 32 bits of the 48-bit integer only, and its low 16-bit is set to a random value. This is a pseudo-random generator

Perl uses the functions rand () and srand () to provide basic tools for generating random (or rather, "pseudo-random") strings. These functions do not use encryption to provide security, so do not use them to encrypt your financial information. However, if you need to design a simple random number generator for your ne
