如何以最简单的方式向数组添加键和值

Question

I would like to know the simplest way to add the value of the $titles->post_title to become the key and value of an array.

Here is my code:

$data_from_database = array();

$titles = get_posts( array( 

        'post_type' => 'resort',
        'order' => 'ASC'
    ) ); 

foreach($data_from_database as $field_key => $field_value) {
    $field['choices'][$field_key] = $field_value;
    $field['choices'][$field_value] = $field_value;
}

Desired result:

 $data_from_database = array('1value' => '1value', '2value' => '2value', 
 '3value' => '3value');

I have looked and read other posts about this but wasnt able to find any info to achieved what i want to do.

Thanks for your answers in advance

Thanks for the answers guys..

I figured it out by using this code.

$data_from_database = array();

  $myarray = array();

    $titles = get_posts( array( 'post_type' => 'resort') ); 

    $new_title = wp_list_pluck($titles, 'post_title', 'post_title');


// reset choices
$field['choices'] = array();


// if has rows
 foreach($new_title as $field_key => $field_value) {
    $field['choices'][$field_key] = $field_value;
}


// return the field
return $field;

wordpress has a built in function to automatically push values and keys to an array
