  This article mainly introduces the PHP implementation to separate the array by the specified number. Need friends can come to the reference, I hope to help you.

The code is as follows:/**  *   * separates the array by the specified number  * @param array $array the arrays to be split  * @param int $groupNum The number of groups to be divided  */ Public Function Splitarray ($array, $groupNum) {    if (empty ($array)) return array ();      //array Total length     $allLength = count ($array);      //number     $groupNum = Intval ($groupNum);      //Start position     $start = 0;      //partitioning of the number of elements in the array     $enum = (int) ($allLength/$groupNum);      //result set     $result = array ();       if ($enum > 0) {         //part of the number of elements in the array to be divisible into arrays in the group       & nbsp $firstLength = $enum * $GROUPNUM;         $firstArray = array ();         for ($i =0 $i < $firstLength $i + +) {            Array_push ($fir Starray, $array [$i]);             unset ($array [$i]);                for ($i =0 $i < $groupNum; $i + +) {             // From the specified start position and length intercept element in the original array to the new array             $result [] = Array_slice ($firstArray, $start, $enum);              //Start position plus number of cumulative elements             $start + = $enu M        }        //The remainder of the array is added to the first few items of the result set,    ,     $secondLength = $allLength-$firstLength;         for ($i =0 $i < $secondLength $i + +) {            Array_push ($re sult[$i], $array [$i + $firstLength]);        }    }else{        for ($i =0 $i < $allLength; $i + +) {  & nbsp         $result [] = Array_slice ($array, $i, 1);        }    }     return $result; }
