PHP数组切片多维数组

Question

I have an multidimensional array but need to make it smaller. This is an easy question I believe. I need to remove 1 array in jsonresult array, the first one but preserve the other in the next array. I have tried array_splice but it only keeps one.

Array
(
[searchword] => search word
[jsonresult] => Array
    (
        [0] => Array // THIS ONE, KEEP ITS CHILDREN MOVE UP
            (
                [0] => Array
                    (
                        [id] => 14889770
                    )
                   [1] => Array
                    (
                        [id] => 14389720
                    )
                   [2] => Array
                    (
                        [id] => 14869723
                    )
            )        

           [1] => Array // THIS ONE, KEEP ITS CHILDREN MOVE UP
            (
                [0] => Array
                    (
                        [id] => 14889722
                    )
                   [1] => Array
                    (
                        [id] => 14389711
                    )
                   [2] => Array
                    (
                        [id] => 14869329
                    )
            )           

   )
)

Would like to get:

Array
(
[searchword] => search word
[jsonresult] => Array
    (
       [0] => Array
        (
          [id] => 14889770
        )
                   [1] => Array
                    (
                        [id] => 14389720
                    )
                   [2] => Array
                    (
                        [id] => 14869723
                    )

                   [3] => Array
                    (
                        [id] => 14889722
                    )
                   [4] => Array
                    (
                        [id] => 14389711
                    )
                   [5] => Array
                    (
                        [id] => 14869329
                    )
    )

Answer 1

Try this code. This may not be the correct method but it gives what you need. (As I understand from your question)

//creating a sample array similar to one you given in question.
$arr_test['searchword'] = 'search word';
$arr_test['jsonresult'] = array(array(array('id'=>14889770),array('id'=>14889720)),array(array('id'=>14889780),array('id'=>14889790)));       
//creating new array
$arr_new = array();
//formatting array as you needed it
foreach($arr_test['jsonresult'] as $arr_jsonresult){
    foreach($arr_jsonresult as $jsonresult){        
        $arr_new['jsonresult'][] =  $jsonresult;        
     }
}
//overwriting the specific array key
$arr_test['jsonresult'] = $arr_new['jsonresult'];
//checking output
echo '<pre>';
print_r($arr_test);

This code produces the following output

Array
(
[searchword] => search word
[jsonresult] => Array
    (
        [0] => Array
            (
                [id] => 14889770
            )

        [1] => Array
            (
                [id] => 14889720
            )

        [2] => Array
            (
                [id] => 14889780
            )

        [3] => Array
            (
                [id] => 14889790
            )

    )

)
