Sometimes you may need to know how many elements an array is containing.

For example, you got result from a mysql query in an array. Now you want to show total number of results returned by the query.

There’s a function in php called count() which can do it for you very easily. Use the following in your favourite code editor:

      $my_array = array("value1", "value2", "value3", "value4");
      echo count($myarray);

It will return 4.
