How can PHP developers handle file path concatenation in scripts to accurately access files on different operating systems, such as Linux and Windows shares?

When handling file path concatenation in PHP scripts to access files on different operating systems, developers should use the DIRECTORY_SEPARATOR constant to ensure cross-platform compatibility. This constant represents the directory separator used by the underlying operating system, allowing the script to correctly construct file paths regardless of the platform. 

// Example of handling file path concatenation in PHP using DIRECTORY_SEPARATOR

$directory = 'path' . DIRECTORY_SEPARATOR . 'to' . DIRECTORY_SEPARATOR . 'file.txt';
echo $directory;
