Php is used to obtain the random array list. php is used to obtain the array.
This article describes how to use php to obtain Random Arrays in an array. The specific implementation method is as follows:
Needless to say, directly paste the code. The array_rand in php is abnormal, which breaks through the understanding of normal people and is very tedious.
Example 1:
Copy codeThe Code is as follows: 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:
Copy codeThe Code is as follows: <? 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:
