Example 2: Add a Tournament Bowler - Overwrites the text file

 


This is an example of using file_put_contents() to create a file containing a single string. Useful for simple data structures. Newly submitted data will replace any existing data in the text file. Commonly used with file_get_contents() for displaying and parsing simple strings. Not useful when working with complex data structures.
