Why is there no parameter in PHP's fopen function to set the file pointer to the beginning and move existing content to the end?

The fopen function in PHP does not have a parameter to set the file pointer to the beginning and move existing content to the end because it is not a common use case. However, you can achieve this by using a combination of file handling functions like fseek and fwrite. By using fseek to move the file pointer to the beginning and then writing content to the file using fwrite, you can effectively append new content to the existing file while preserving the old content.

$file = fopen("example.txt", "r+"); // Open the file for reading and writing
fseek($file, 0); // Move the file pointer to the beginning
fwrite($file, "New content to append\n"); // Append new content to the file
fclose($file); // Close the file
