adding elements to an array in PHP

    In PHP, you can add elements to an array using several methods. The most common ways are:

    1. Using the [] operator: This is the simplest method to add an element to an array. If you don't specify a key, PHP will automatically use the next integer index.

      $array = array("apple", "banana");
      $array[] = "cherry"; // Adds "cherry" to the end of the array
    2. Using the array_push() function: This function allows you to add one or more elements to the end of an array.

      $array = array("apple", "banana");
      array_push($array, "cherry", "date"); // Adds "cherry" and "date" to the end
    3. Specifying the key: You can add an element with a specific key by directly setting a value to that key. This is useful for associative arrays.

      $array = array("a" => "apple", "b" => "banana");
      $array["c"] = "cherry"; // Adds a new element with key "c"
    4. Using the array_merge() function: This function is used to combine two or more arrays. If you want to add elements from another array, this is a good option.

      $array1 = array("apple", "banana");
      $array2 = array("cherry", "date");
      $result = array_merge($array1, $array2); // Combines both arrays

    Each of these methods has its use cases depending on what you need to achieve with your array. Remember that in PHP, arrays are dynamic and can grow as you add elements to them.
