glob（）php函数数组格式

Maybe I missed something, but really, I can't find a solution for this.

I want to change the format of the array I get from a glob function.

This is how my code looks now.

$my_files = glob('*.php');

and the result is an array:

array(
    '0' => 'about.php',
    '1' => 'admin-ajax.php',
    '2' => 'admin-footer.php',
    '3' => 'admin-functions.php',
    '4' => 'admin-header.php',
    '5' => 'admin-post.php',
    '6' => 'admin.php',
)

Now this is what exactly I want to have(to change the numbers with the text for each array, respectively):

array(
    'about.php'         => 'about.php',
    'admin-ajax.php'    => 'admin-ajax.php',
    'admin-footer.php'  => 'admin-footer.php',
    'admin-functions.php' => 'admin-functions.php',
    'admin-header.php'  => 'admin-header.php',
    'admin-post.php'    => 'admin-post.php',
    'admin.php'         => 'admin.php',
)

I need this as an array to include it using a variable in this way:

array(
    'name'      => 'Intern download file name',
    'id'        => $prefix .'blog_post_intern_url',
    'type'      => 'select',
    'options'   => $my_files,
),

$arrayWithKeysEqualValues = array_combine($my_files, $my_files);

Try array_combine

$newArray = array_combine($originalArray, $originalArray);
