What potential issues can arise when writing values from an array to a text file in PHP, as demonstrated in the code example?

One potential issue that can arise when writing values from an array to a text file in PHP is that the values may contain special characters that could break the file format or cause unexpected behavior. To solve this issue, it is important to properly escape or encode the values before writing them to the file. One way to achieve this is by using the `fputcsv` function in PHP, which will handle the escaping of special characters for you. 

// Sample array of values
$values = ['John Doe', 'Jane Smith', 'Special Character: "'];

// Open a file for writing
$file = fopen('output.txt', 'w');

// Write the values to the file using fputcsv
fputcsv($file, $values);

// Close the file
fclose($file);
