I m working on a plugin and i would add a page for every value of my database.

But for every refresh, a new page with same name will be added. How can i fix this?

for ($i = 0; $i < count($namepages); $i++) {
       mic_create_new_page($name[$i],$namepages[$i]);    
}

function mic_create_new_page($name, $namepages) {
    global $user_ID;
    if (post_exists($namepages) == false) {
        $new_post = array(
            'post_title' => 'Services ' . $name,
            'post_content' => 'New post content',
            'post_status' => 'publish',
            'post_date' => date('Y-m-d H:i:s'),
            'post_author' => $user_ID,
            'post_type' => 'page',
            'post_name' => $namepages
        );
        $post_id = wp_insert_post($new_post);
    }
}
    
register_activation_hook(__FILE__, 'create_new_page');

If this code is in functions.php or directly in plugin code, the for loop at the top will run every time Wordpress is loaded, and the hook at the end refers to a function which doesn't exist.

So probably what you want is to put the top code in a function:

function zed93_create_new_page {
    for ($i = 0; $i < count($namepages); $i++) {
        mic_create_new_page($name[$i],$namepages[$i]);    
    }
}

And correct your hook to:

register_activation_hook(__FILE__, 'zed93_create_new_page');

Note the function name can be anything, but making it unique to your project helps avoid collisions with other plugins / themes.
