I want to use the 'id' array of Array 1 to order all other sibling arrays in Array 2. The 'id' array is supposed to act as the schema for all other arrays in $array1
and $array2
.
This is easier explained with an example.
I have the following array, Array 1 :
Array
(
[id] => Array
(
[0] => 1
[1] => 3
[2] => 2
)
[headline] => Array
(
[0] => test 1
[1] => test 3
[2] => test 2
)
)
And another array, Array 2:
Array
(
[id] => Array
(
[0] => 1
[1] => 2
[2] => 3
)
[headline] => Array
(
[0] => tc test 1
[1] => tc test 2
[2] => tc test 3
)
)
That I would like to look like the following:
Array
(
[id] => Array
(
[0] => 1
[1] => 3
[2] => 2
)
[headline] => Array
(
[0] => tc test 1
[1] => tc test 3
[2] => tc test 2
)
)
Right now I'm trying to force it with foreach statements (and failing), but there has to be a better way.
This is a “fake” sort, because I fill an empty array through a foreach()
loop, then I replace original array:
$array1 = [ 'id' => [ 1,3,2 ], 'headline' => [ 'test 1','test 3','test 2' ] ];
$array2 = [ 'id' => [ 1,2,3 ], 'headline' => [ 'test 1','test 2','test 3' ] ];
$result = array();
foreach( $array1['id'] as $val )
{
$key = array_search( $val, $array2['id'] );
$result['id'][] = $array2['id'][$key];
$result['headline'][] = $array2['headline'][$key];
}
$array2 = $result;
print_r( $array2 );
Output:
Array
(
[id] => Array
(
[0] => 1
[1] => 3
[2] => 2
)
[headline] => Array
(
[0] => test 1
[1] => test 3
[2] => test 2
)
)
I execute a foreach
loop through criterion 'id' array, find each value in array to be sorted, retrieve its key and use it to add values to resulting array.
Not so proud of this solution, but this is.
