Create a web page using PHP and HTML that contains a list of movie names available for rent (at least 10 movies), so that each time you visit the home page, you see a different order of movies in the list. The movie names are required.
2) The rental price for each movie ranges between $1.99 to $7.99.
• Create an associative array with a code for the movie as the key (e.g., movie1, movie2, etc.) and the associated rental price as the value. Display the array using the print_r() function.
• Sort the array according to the rental price in ascending order. Display the array again using the print_r() function.
• Calculate and display the average rental price for a movie.
• Find and display the two highest and two lowest rental prices.
Display these results on the same page. Again, display appropriate warning/error messages as needed.
Hi,
Save the following code in .php file. Most of the code is readable and well commented for better understanding.
<!DOCTYPE html> <html> <head> <meta http-equiv="Content-Type" content="text/html; charset=UTF-8"> <title>Movies For Rent</title> </head> <body> <?php /* Create an associative array with a code for the movie as the key (e.g., movie1, movie2, etc.) and the associated rental price as the value. Display the array using the print_r() function. */ /*Movies Associate Array*/ $movies = array( "movie1" => 7.45, "movie2" => 3.50, "movie3" => 2.50, "movie4" => 4.25, "movie5" => 1.50, "movie6" => 6.00, "movie7" => 2.70, "movie8" => 5.75, "movie9" => 6.10, "movie10" => 3.80, "movie11" => 2.75 ); /*Printing as it is using print_r and true for pretty print*/ echo "<h4>Movies</h4>"; echo "<pre>" . print_r($movies, true) . "</pre>"; ?> <hr> <?php /* Sort the array according to the rental price in ascending order. Display the array again using the print_r() function. */ /*Sorting by value [price] using """asort"""*/ asort($movies); /*Printing after sorting using print_r and true for pretty print*/ echo "<h4>Movies sorted by rental prices</h4>"; echo "<pre>" . print_r($movies, true) . "</pre>"; ?> <hr> <?php /*Calculate and display the average rental price for a movie.*/ $total_value_of_movies = array_sum($movies); //sum of all values in the associated array $movies_count = count($movies); $average = $total_value_of_movies / $movies_count; echo "<p>Average Movie Rental Price: <strong>" . round($average, 2) . "$</strong></p>" ?> <hr> <?php /* Find and display the two highest and two lowest rental prices. Display these results on the same page. */ $rental_prices = array_values($movies); //getting only rental prices that too already sorted //Displaying last two values of the prices array echo "<p>Top Two Highest Rental Prices: <strong>" . $rental_prices[$movies_count - 1] . ", " . $rental_prices[$movies_count - 2] . "</strong></p>"; echo "<br>"; //for new line //Displaying first two values of the prices array echo "<p>Top Two Lowest Rental Prices: <strong>" . $rental_prices[0] . ", " . $rental_prices[1] . "</strong></p>"; ?> </body> </html>
Hope this helps.
All the best.
