  PHP MySQL Connection management AND Database Operations The initial step involves establishing a connection to work with the database in PHP. PHP will therefore need to authenticate itself: we say that it establishes a connection with MySQL. To connect using PDO (PHP Data Objects), we need to instantiate the PDO class, passing the database source (server + database name) and a username and password as parameters to the constructor. Method 1: Using a Function <?php //PDO connexion function Connexion ( ) { $hostname = "localhost" ; $username = "The_name_of_your_user" ; $password = "your_password" ; $databasename = "The_name_of_your_DB" ; try { $conn = new PDO ( "mysql:host= $hostname ;dbname=The_name_of_your_DB" , $username , $password ); // set the PDO error mode to exception $conn -> setAttribute (PDO:: ATTR_ERRMODE , PDO:: ERRMODE_EXCEPTION ); echo "C...

  ScrollView Vs FlatList Vs SectionList C omponents in “ React Native” To display the menu items on the mobile screen and to offer a good UX, users should be able to scroll up and down the menu, you can use ScrollView which will load the items immediately after the component has been loaded so all data is stored in RAM. The ScrollView component has only one rule. It must be bounded by a height in order to work. This means we need to make sure that all the parent views have a bounded high. An app using this component would render all items in the list at once.  The output of the code snippet is : The FlatList component serves as an effective tool to render a large scrollable list of items. Employing a technique known as lazy rendering : items are rendered as the user encounters them in the app and are removed when the user scrolls away from them. So, the FlatList renders large lists without sacrificing app performance. This results in faster rendering and great perfor...
