Answer 1

Solution 1: Hope this simple foreach to get the desired result

Try this code snippet here

<?php
ini_set('display_errors', 1);
$where = array('id'=>array(12,13,14),'date'=>array('1999-06-12','2000-03-21','2006-09-31'));

$result=array();
foreach($where["id"] as $key => $value)
{
    $result[]=array($value,$where["date"][$key]);
}

Solution 2: Here we are using array_walk to achieve the same result

Try this code snippet here

<?php
ini_set('display_errors', 1);
$result=array();
$where = array('id'=>array(12,13,14),'date'=>array('1999-06-12','2000-03-21','2006-09-31'));

array_walk($where["id"], function($value,$key) use(&$result,&$where){
    $result[]=array($value,$where["date"][$key]);
});
print_r($result);

Solution 3: Here we are using array_shift on $where["date"].

Try this code snippet here

<?php
ini_set('display_errors', 1);
$result=array();
$where = array('id'=>array(12,13,14),'date'=>array('1999-06-12','2000-03-21','2006-09-31'));

foreach($where["id"] as $value)
{   
    $result[]=array($value,  array_shift($where["date"]));
}
print_r($result);
