将一个命名键放在数组中的数字键之前

Question

Need to compare two arrays

Working example

$array1 = array("a" => "green", "red", "blue");
$array2 = array("b" => "green", "yellow", "red");
$result = array_intersect($array1, $array2);

Array1 Output:

Array ( [a] => green [0] => red [1] => blue ) 

When I do Like this

$array1 = array();

while($fetch = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC))
{
    $array1[] = $fetch['color'];
}  

I get this output:

Array ([0] => gren [1] => red [2] blue

How do I add the "a" to the array and make the first color be number zero?

This adding the "a" but it gets the zero number

array_unshift($array1,"a");

LIKE

Array ( [0] => a [1] => green

I want this

Array ( [a] => green [0]

I'm not sure why you want to do this, but here's how:

$array1 = array();
while ($fetch = sqlsrv_fetch_array($stmt, SQLSRV_FETCH_ASSOC))
    if (empty($array1)) {
        $array1['a'] = $fetch['color'];
    } else {
        $array1[] = $fetch['color'];
    }
}
