Paste a piece of code. You don't need to say much about getting random arrays in php. Directly paste the code. The array_rand in php is abnormal. It breaks through normal people's understanding and is tedious.
Example 1
| The code is as follows: |
Copy code |
Function create_random_ids ($ min, $ max, $ limited)
{
$ _ Base_ids = range ($ min, $ max );
$ _ Temp_key = array_rand ($ _ base_ids, min (count ($ _ base_ids), $ limited + 10 ));
// Splicing
$ Ids = array ();
For ($ x = 0; $ x <count ($ _ temp_key); $ x ++ ){
$ Ids [] = $ _ base_ids [$ _ temp_key [$ x];
}
Return $ ids;
} |
Example 2
| The code is as follows: |
Copy code |
<? Php
$ A = array (, 8 );
Echo "$ a original sequence: Foreach ($ a as $ v)
Echo $ v. "t ";
Shuffle ($ );
Echo "<br/> $ a is in the following order: Foreach ($ a as $ v)
Echo $ v. "t ";
?> |
The first result is:
The second result is:
The third result is:
