php中的数组键和值

Question

I have one array:

$array1=['0'=>'field_1','1'=>'field_2'];

My expect output result to my new array:

$newarray=['field_1'=>field1_val,'field_2'=>field2_val];

I try that code:

$newarray=array();
foreach($array1 as $value){
    $newarray[] = $value;
}
print_r($newarray);

But it's seem to be not working. Anyone can help me please?

Answer 1

try this

$array1=['0'=>'field_1','1'=>'field_2'];
    $newarray=array();
    foreach($array1 as $value){
         $newarray[$value] = $value;
    }
    print_r($newarray);

Answer 2

Try this :

$newarray=array();
    foreach($array1 as $value){
         $newarray[$value] = $value;
    }

You can also use array_combine :

array_combine — Creates an array by using one array for keys and another for its values.

Syntax:

array_combine ($keys ,$values );

Code:

$newarray = array_combine($array1, $newarray);
