The order of numbers and associative arrays in php is disrupted_PHP tutorial

Regarding array sorting, PHP has a built-in shuffle() function, which can rearrange the array sorting, but this function "will delete the original key names instead of just reordering". If an associative array is passed in, then the associative array The key name will be lost.

The solution is as follows: both associative arrays and index arrays can be used

The code is as follows

代码如下	复制代码
function array_shuffle($array) {     //不是数组     if(!is_array($array)) {         return array();     }     //如果为空或者只有1项     if(($count=count($array))<=1){         return $array;     }          //得到打乱的键     $rand_keys = array_rand($array, count($array));     $newArr=array();     foreach($rand_keys as $v) {         $newArr[$v] = $array[$v];     }     return $newArr; }

Copy code

function array_shuffle($array)
{
//Not an array
If(!is_array($array)) {
         return array();
}
//If it is empty or there is only 1 item
If(($count=count($array))<=1){
          return $array;
}
         
//Get the scrambled key
$rand_keys = array_rand($array, count($array));
$newArr=array();
foreach($rand_keys as $v) {
         $newArr[$v] = $array[$v];
}
Return $newArr;
}
