What potential issues can arise when trying to read a file using PHP on an Apache server compared to XAMPP?

One potential issue that can arise when trying to read a file using PHP on an Apache server compared to XAMPP is file permission errors. This is because Apache server may have different permission settings compared to XAMPP, leading to access denied errors when trying to read a file. To solve this issue, you can adjust the file permissions or use the correct file path to ensure that Apache has the necessary permissions to read the file. 

// Example code snippet to read a file with proper file path
$file = '/path/to/file.txt';

if (file_exists($file)) {
    $content = file_get_contents($file);
    echo $content;
} else {
    echo "File not found.";
}
