What potential issue could arise from using multiple fwrite statements in PHP?

Using multiple fwrite statements in PHP can lead to performance issues as each fwrite call will result in a separate I/O operation, which can be inefficient when writing to a file multiple times. To solve this issue, you can buffer the data in memory and then write it to the file in a single fwrite call. 

// Open the file in write mode
$file = fopen("data.txt", "w");

// Buffer the data in memory
$data = "First line\n";
$data .= "Second line\n";
$data .= "Third line\n";

// Write the buffered data to the file in a single fwrite call
fwrite($file, $data);

// Close the file
fclose($file);
