Example 4: Add a Tournament Bowler - Overwrites text file in a simple string (cannot iterate as an array)

 

Display List of Bowlers



This is an example of using file_get_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 as you cannot iterate using a loop through the string.
