如何从php数组中排除值[关闭]

Question

I have the following array in a WordPress query options which is used to output product categories, and I need to exclude certain values from it by category ID, how can I do so?

$args = apply_filters( 'storefront_product_categories_args', array(
            'limit'             => 12,
            'columns'           => 3,
            'child_categories'  => 0,
            'orderby'           => 'name',
            'order'             => 'asc',
            'title'             => __( '', 'storefront' ),

Many thanks.

Removing items from a PHP array by key is done using the unset function:

$array = array(
    'limit'             => 12,
    'columns'           => 3,
    'child_categories'  => 0,
    'orderby'           => 'name',
    'order'             => 'asc',
    'title'             => 'something',
);

unset( $array[ 'columns' ] );

var_dump( $array );
