The example in this article describes how to edit and save files in PHP. Share it with everyone for your reference. The details are as follows:

save_file.php:

session_start();
$handle = fopen($_POST['original_file_name'], "w");
$text = $_POST['file_contents'];
if(fwrite( $handle, $text) == FALSE){
 $_SESSION['error'] = 'There was an error';
}else{
 $_SESSION[' error'] = 'File edited successfully';
}
fclose($handle);
header("Location: ".$_POST['page']);
?>

read_file.php:

"http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd" >
