How can you delete the entire content of a text file in PHP?

To delete the entire content of a text file in PHP, you can simply open the file in write mode and use the `file_put_contents()` function with an empty string as the content parameter. This will overwrite the existing content with an empty string, effectively deleting all the content in the file. 

$file = 'example.txt';

// Open the file in write mode to delete the content
$fileHandle = fopen($file, 'w');

// Write an empty string to the file to delete its content
file_put_contents($file, '');

// Close the file handle
fclose($fileHandle);
