How can the error "Warning: fopen(templates/Array): failed to open stream: No such file or Directory" be resolved in the given PHP code snippet?

The error "Warning: fopen(templates/Array): failed to open stream: No such file or directory" occurs because the fopen function is trying to open a file named "Array" in the "templates" directory, which does not exist. To resolve this issue, you need to specify the correct file path in the fopen function call.

$file = 'templates/example.txt'; // Specify the correct file path
$handle = fopen($file, 'r');
if ($handle) {
    // File handling code
    fclose($handle);
} else {
    echo "Error opening the file.";
}
