PHP阵列联盟（线性产品）

Question

是否有任何方法来获得两个或更多数组的联合？

例如：

$array1 = [x1, x2, x3]; 

$array2 = [y1, y2, y3]; 

// and the result will be 

$array2 = [x1 y1, x1 y2, x1 y3, x2 y1, x2 y2 ,.....]; 

Answer 1

这应该为你工作：

<?php 

    $array1 = array("x1", "x2", "x3" 
    $array2 = array("y1", "y2", "y3"); 

    $array3 = array(); 

    // and the result will be 
    //$array3 = [x1 y1, x1 y2, x1 y3, x2 y1, x2 y2 ,.....]; 


    for($count = 0; $count < count($array1); $count++) { 

     for($countArrayTwo = 0; $countArrayTwo < count($array2); $countArrayTwo++) 
      $array3[] = $array1[$count] . " " . $array2[$countArrayTwo]; 

    } 

    print_r($array3); 

?>
