Php method for random replacement of elements in a logarithm Group

This article mainly introduces the php method for random replacement of elements in the logarithm group. the Function of random replacement of elements in the logarithm group is implemented through a user-defined function, which involves related techniques related to php operations on arrays, for more information about how to randomly change elements in a php logarithm group, see the example in this article. Share it with you for your reference. The specific analysis is as follows:

This is a user-defined function for random replacement of php Array elements. php already has a built-in shuffle ($ Array) function with the same functions. this code can be used as a reference.

// I noticed that there is already a built-in function that// does the same - so don't use mine ;-)//// --> shuffle($Array);//// http://de2.php.net/manual/de/function.shuffle.php//function RandomizeArray($array){  // error check:  $array = (!is_array($array)) ? array($array) : $array;  $a = array();  $max = count($array) + 10;  while(count($array) > 0){        $e = array_shift($array);    $r = rand(0, $max);    // find a empty key:    while (isset($a[$r])){      $r = rand(0, $max);    }        $a[$r] = $e;  }  ksort($a);  $a = array_values($a);  return $a;}

Example:

/*** Example:*/$test_array = array('why','dont','visit','www','jonas','john','de',':-)');print implode(", ", $test_array);print "\n";print implode(", ", RandomizeArray($test_array));/*Example output:why, dont, visit, www, jonas, john, de, :-)www, de, jonas, john, visit, why, :-), dont*/
