I have done some changes to this, you are right there is a lot of wrong with this.

But even after changing this, it is still not working for these users.

	/**
	 * # Set Profile Views Number .
	 */
	function set_profile_views( $profile_ID ) {

	 	// The user's IP address
	    $user_ip = $_SERVER['REMOTE_ADDR'];
	    $ip_key = 'profile_views_ip'; // The IP Address post meta key
	    $views_key = 'profile_views_count'; // The views post meta key

	    // The current post views count
		$count = get_post_meta( $profile_ID, $views_key, true );
		
		//Check day
		$day = date("l");
		$day_table = 'profile_views_day'; // Set the day to check
		$setDay = get_post_meta( $profile_ID, $day_table , true );
		$checkDay = metadata_exists('post', $profile_ID, 'profile_views_day');

		//Check if Viewcount and IP Table already exist
		$check_ip = metadata_exists('post', $profile_ID, 'profile_views_ip');
		$check_views = metadata_exists('post', $profile_ID, 'profile_views_count');

		//Bank IT-Tables
		$blank_array = array();
		$json_array = json_encode( $blank_array );

		if ( is_page() ) {
			//Check if Views already exist
			if(!$check_views){
				add_post_meta( $profile_ID, $views_key, 0 );
			}

			//Check if IP-Meta already exist
			if(!$check_ip){
				add_post_meta( $profile_ID, $ip_key, $json_array );
			}

			if(!$checkDay){ //Check if day is set in database
				add_post_meta( $profile_ID, $day_table , $day );
			}else{
				if($day != $setDay){ // Check if day is the same as database
					update_post_meta( $profile_ID, $day_table , $day );
					update_post_meta( $profile_ID, $ip_key, $json_array);
				}
			}

			// Array of IP addresses that have already visited the post.
			if ( '' != get_post_meta( $profile_ID, $ip_key, true ) ) {
			    $ip = json_decode( get_post_meta( $profile_ID, $ip_key, true ), true );
			} else {
				$ip = array();
			}

			// The following checks if the user's IP already exists
			for ( $i = 0; $i < count( $ip ); $i++ ) {
			    if ( $ip[ $i ] == $user_ip ) {
			        return false;
			    }
			}

			// Update and encode the $ip array into a JSON string
			$ip[ count( $ip ) ] = $user_ip;
			$json_ip = json_encode( $ip );

			// Update the post's metadata
			$count++;
			update_post_meta( $profile_ID, $views_key, $count ); // Update the count
			update_post_meta( $profile_ID, $ip_key, $json_ip ); // Update the user IP JSON obect
		}
