Dynamically Generate Functions and Hooks

Question

I'm trying to find if it's possible to dynamically generate functions and hooks. All functions do the same thing, and all hooks are essentially the same.

Here's an example of a hook/function combo:

add_action( 'woocommerce_single_product_summary', 'cx_inputKVA_show', 5 );
function cx_inputKVA_show() {
    global $product;
    // Do not show this on variable products
    if ( $product->product_type <> 'variable' ) {
        $inputKVA = get_post_meta( $product->id, 'cx_inputKVA', true );
        if ( $inputKVA <> '' ) {
            echo '<div class="woocommerce_msrp">';
            _e( 'Input KVA: ', 'woocommerce' );
            echo '<span class="woocommerce-cx_inputKVA">' . _e( $inputKVA ) . '</span>';
            echo '</div>';
        }
    }
}

I want to use an array like:

$fieldset = array(
    array(
        1 => 'slug',
        2 => 'title'
    )
    array(
        1 => 'slug',
        2 => 'title'
    )
);

And then use a foreach() loop to generate 3 hooks and 3 functions for each nested array. Before, I was just writing each one separately, but now I need to generate for 23 items and it's too much code, too messy to change.

It would make the hook like:

add_action( 'woocommerce_single_product_summary', 'cx_[plug]_show', 5 );

and the function like

function cx_inputKVA_show() {
    global $product;
    // Do not show this on variable products
    if ( $product->product_type <> 'variable' ) {
        $[plug] = get_post_meta( $product->id, 'cx_[plug]', true );
        if ( $[plug] <> '' ) {
            echo '<div class="woocommerce_msrp">';
            _e( '[title]: ', 'woocommerce' );
            echo '<span class="woocommerce-cx_[plug]">' . _e( $[plug] ) . '</span>';
            echo '</div>';
        }
    }
}

Answer------------------ Since Milo is a genius, I got this done much simpler by just looping through the array inside of the function, instead of trying to generate a new function dynamically for each item. The array contains 'slug' and 'title' attributes, and here's the function:

function cx_product_field() {
    global $fieldset;
    foreach ( $fieldset as $field ){
        woocommerce_wp_text_input(
            array( 
                'id' => 'cx_'.$field['slug'], 
                'class' => 'wc_input_text', 
                'label' => __( $field['title'], 'woocommerce' )
            ) 
        );
    }
}
