在PHP中将多维数组转换为有组织的数组

Question

I need to convert an array in this format:

Array ( 
    [size] => P 
    [code] => Array ( 
        [0] => C01 
        [1] => B01 
        [2] = A02
    ) 
)

to multiple ones like this:

Array ( [size] => P [code] => C01 )
Array ( [size] => P [code] => B01 )
Array ( [size] => P [code] => A02 )

How would I do that using php code?

Answer 1

You need to loop throught items of code array and push values into new array or new variable.

foreach($arr["code"] as $item){
    @$newArr[] = [
        "size" => "P",
        "code" => $item
    ];
}
var_dump($newArr);
