What are the common reasons for fopen() errors in PHP scripts and how can they be resolved?

Common reasons for fopen() errors in PHP scripts include incorrect file paths, insufficient permissions, and file not existing. To resolve these issues, ensure that the file path is correct, set appropriate file permissions, and check if the file exists before attempting to open it. 

$file = 'path/to/file.txt';

if (file_exists($file)) {
    $handle = fopen($file, 'r');
    // Continue with file operations
    fclose($handle);
} else {
    echo "File does not exist.";
}
