PHP CSVImporter - php

Question

I had a script called CSVimporter V3 for PHP that I used to run on a website and it worked fine. A couple of years later I've now dug out the same script to use on another project, all works okay except the CSV files are being read as one long line, as opposed to header row and multiple lines.
Here is part of the script.
Any ideas why it would be being read as a long line?
<?php
// Reference session variable for short-hand
$f = &$_SESSION['csv_file'];
// Open file - fp = file pointer
if (!$fp = #fopen($f, 'r')) {
error(L_ERROR_PREVIEW_NO_FILE);
} else {
// Array to store each row to be inserted
$batch = array();
// Row counter
$rc = 0;
// Work out starting row
switch ($_SESSION['csv_first_row']) {
case 'data':
$start_row = 0;
break;
default:
$start_row = 1;
}
// Get contents, while below preview limit and there's data to be read
while ($data = fgetcsv($fp, 1024, delimiter_to_char($_SESSION['csv_delimiter']))) {
if ($rc < $start_row) {
// Incremement counter
$rc++;
// Go to next loop
continue;
} else {
// Array to store data to be inputted
$values = array();
// Loop data
for ($i = 0; $i < count($data); $i++) {
// If data is wanted, put data into array
if (array_key_exists($i, $column_index)) {
$values[$column_index[$i]] = $data[$i];
}
}
// Sort array into correct order by index
ksort($values);
// Join values together and store in array
$batch[] = '("' . implode('", "', str_replace('"', '\"', $values)) . '","'.$accti.'","'.$impt.'")';
}
}
}
// Close the file
fclose($fp);

I added this at the top of the code and it all works now!
ini_set('auto_detect_line_endings', true);
