How can developers effectively utilize PHP documentation to understand file handling functions and modes?

To effectively utilize PHP documentation to understand file handling functions and modes, developers should refer to the official PHP manual or documentation on php.net. They can search for specific functions related to file handling, such as fopen(), fread(), fwrite(), fclose(), etc., to understand their usage and parameters. Additionally, developers can also learn about different file handling modes like 'r', 'w', 'a', 'r+', 'w+', 'a+', 'x', 'x+', 'c', and 'c+' to determine how they affect file operations. 

// Example code snippet demonstrating the usage of fopen() function with different modes
$filename = "example.txt";
$file = fopen($filename, "r"); // Open file for reading
if ($file) {
    $contents = fread($file, filesize($filename)); // Read file contents
    fclose($file); // Close the file
    echo $contents; // Output file contents
} else {
    echo "Unable to open file.";
}
