Are there any specific differences in PHP behavior between Windows and Linux that could be causing this issue?

Issue: The PHP file_get_contents function may behave differently on Windows and Linux due to differences in file path handling. To solve this issue, use the DIRECTORY_SEPARATOR constant to build file paths in a platform-independent way. PHP code snippet:

// Define the file path using DIRECTORY_SEPARATOR
$file_path = 'path' . DIRECTORY_SEPARATOR . 'to' . DIRECTORY_SEPARATOR . 'file.txt';

// Use file_get_contents with the updated file path
$file_contents = file_get_contents($file_path);

// Output the file contents
echo $file_contents;
