推荐答案

使用mt_rand（min，max）生成值。



对于字母值，在循环中使用它三次，范围跨越1到26（或A至Z的ascii值当量）。在任何一种情况下，都巧妙地从中创建角色值。



然后，使用范围（0,9）循环十次。循环通过你想要的任意数字。



所以 - 看起来应该是这样的：

Use mt_rand(min,max) to generate values.

For alphabetic values, use it in a loop three times with a range that spans 1 through 26 (or ascii value equivalents of A through Z). In either case, cunningly create character values out of them.

Then, loop through it ten times with the range (0, 9). Loop through for as many digits as you wish.

So - it should look something like:

randString =''; //初始化为

为（

randString = ''; // initialize to empty for(

i = 0;
