What are the potential challenges of converting XLS to CSV in PHP, especially when dealing with binary formats like XLS?

One potential challenge of converting XLS to CSV in PHP, especially when dealing with binary formats like XLS, is handling the conversion of special characters and formatting that may not directly translate to CSV format. To solve this issue, you can use a library like PHPExcel to read the XLS file and extract the data, then manually format and write the data to a CSV file. 

<?php
require 'PHPExcel/PHPExcel.php';

$inputFile = 'example.xls';
$outputFile = 'example.csv';

$excelReader = PHPExcel_IOFactory::createReaderForFile($inputFile);
$excelObj = $excelReader->load($inputFile);

$writer = PHPExcel_IOFactory::createWriter($excelObj, 'CSV');
$writer->setDelimiter(',');
$writer->setEnclosure('');
$writer->setLineEnding("\r\n");
$writer->setSheetIndex(0);
$writer->save($outputFile);

echo "XLS file converted to CSV successfully.";
?>
