How can the error "failed to open stream: No such file or directory" be resolved in PHP?

The error "failed to open stream: No such file or directory" in PHP occurs when the file being accessed does not exist in the specified directory. To resolve this issue, you should check the file path and ensure that the file exists in the correct location.

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

if (file_exists($file_path)) {
    $file = fopen($file_path, 'r');
    // Perform operations on the file
    fclose($file);
} else {
    echo 'File does not exist.';
}
