foreach loop in wp_query witth multiple taxonomies

I need wp_query with multiple custom taxonomy.I wrote this following code but it is generating error

Parse error: syntax error, unexpected ‘foreach’ (T_FOREACH), expecting ‘)’ in C:\xampp\htdocs\wpcompare\wp-content\plugins\custom-post-type-ui\replace_custom_tags_content.php on line 68

This is my code`

$args = array(
    'post_type' => 'product',
    'tax_query' => array(
        'relation' => 'AND',
//print_r($taxonomy_array);

foreach($taxonomy_array as $taxonomy_array_value){
$taxonomy_array_value_main = "'".$taxonomy_array_value."'";
//echo $taxonomy_array_value_main;
$term_value_array = array();
//print_r($term_array[$taxonomy_array_value]);
foreach($term_array[$taxonomy_array_value] as $term_value){
    //echo $term_value;

        array_push($term_value_array,$term_value);
    }

$term_name = "'" . implode("','", $term_value_array) . "'";
//echo $term_name;
        array(
            'taxonomy' => $taxonomy_array_value_main,
            'field' => 'slug',
            'terms' => array( $term_name )
        )

}
);
$query = new WP_Query( $args );

Can anyone tell me how to fix error OR if I am doing in a wrong way then tell me another solution for writing w-query for multiple custom taonomies
