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:

The 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:

The Code is as follows:

<? Php
$ A = array (, 8 );
The original order of echo "$ a is:

";
Foreach ($ a as $ v)
Echo $ v. "t ";
Shuffle ($ );
Echo"
$ A is in the following order: ";
Foreach ($ a as $ v)
Echo $ v. "t ";
?>


The first result is:

The second result is:
