How can whitespace at the end of a string impact file operations in PHP?

Whitespace at the end of a string can impact file operations in PHP by causing unexpected behavior, such as file not found errors or incorrect file paths. To solve this issue, you can use the `trim()` function in PHP to remove any leading or trailing whitespace from a string before using it in file operations. 

// Example code snippet to remove whitespace from a string before using it in file operations
$file_path = trim("path/to/file.txt");
$file_contents = file_get_contents($file_path);

// Now $file_path does not contain any leading or trailing whitespace
// Proceed with file operations using $file_path
