php - 在多维数组中插入一个数组

Question

I have a multidimensional array where I want to insert an other array inside it with a var array.

My aim is to insert some element array with if statement. In fact I want to build a kind of conditionnal array.

Here an example

$inserted_array[] = array( 
    'name' => 'name',
    'desc' => 'a description',
    'id' => 'an id',
    'type' => 'image',
    'std' => '',
);
$inserted_array[] = array(
    'name' => 'name',
    'desc' => 'a description',
    'id' => 'an id',
    'type' => 'image',
    'std' => '',
);

$main_arrays[] = array(
    'id'    => '1234',
    'title' => 'a title',
    'icon'  => 'icon-1',
    'fields' => array(
        array( 
            'name' => 'name',
            'desc' => 'a description',
            'id' => 'an id',
            'type' => 'image',
            'std' => '',
        ),
        //$inserted_array here for example
        array(
            'name' => 'name',
            'desc' => 'a description',
            'id' => 'an id',
            'type' => 'image',
            'std' => '',
        ),
    )
);

How can I do this kind of thing?

Answer 1

If you want to insert the $inserted_array into $main_arrays[]['fields] at a given $position

You can achieve it by using array_splice function

array_splice($main_arrays[$index]['fields'], $position, 0, $inserted_array);

$index being the $main_arrays index in wich you want to insert the $inserted_array

$position being the position wich at you want to insert you're array
