What are some common reasons for the error message "No such file or directory" in PHP scripts?

The error message "No such file or directory" typically occurs in PHP scripts when the specified file or directory does not exist in the specified location. This can happen due to incorrect file paths, misspelled file names, or permission issues. To solve this error, double-check the file path, ensure the file exists in the specified location, and verify that the PHP script has the necessary permissions to access the file.

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

if (file_exists($file_path)) {
    // File exists, proceed with your code here
    $file_contents = file_get_contents($file_path);
    echo $file_contents;
} else {
    echo "File does not exist.";
}
