What is the significance of using full file paths when working with file manipulation functions in PHP?

Using full file paths when working with file manipulation functions in PHP is important because it ensures that the script can accurately locate and access the desired files regardless of the current working directory. This helps prevent errors and ensures consistency in file operations. 

// Example of using full file paths in PHP file manipulation
$filePath = '/var/www/html/myproject/data/file.txt';

// Reading file contents
$fileContents = file_get_contents($filePath);

// Writing to a file
file_put_contents($filePath, 'Hello, World!');

// Checking if a file exists
if (file_exists($filePath)) {
    echo 'File exists!';
}
