What is the purpose of using implode with a delimiter in PHP when processing file data?

When processing file data in PHP, using implode with a delimiter can be helpful to combine an array of data into a single string with a specified separator. This can be useful when you need to format the data in a specific way before writing it to a file or displaying it to the user. 

// Read file data into an array
$fileData = file('data.txt', FILE_IGNORE_NEW_LINES);

// Combine array elements with a comma delimiter
$combinedData = implode(',', $fileData);

// Output the combined data
echo $combinedData;
