What are some best practices for handling file writing in PHP to avoid limitations on the number of entries saved in a single line?

When writing data to a file in PHP, it's important to avoid limitations on the number of entries saved in a single line by using a delimiter to separate each entry. This allows for easier parsing of the data later on. One common delimiter is a comma (`,`), but you can choose any character that won't appear in your data. By using a delimiter, you can easily read and process the data without running into issues with line length limitations. 

// Example of writing data to a file with entries separated by commas
$data = ["entry1", "entry2", "entry3"];
$file = fopen("data.txt", "a");

// Write each entry to the file with a comma delimiter
fwrite($file, implode(",", $data) . PHP_EOL);

fclose($file);
