Php Class to build database with txt files.

PHP TxtDb Class

I have written this class for simple usage for txt files as database. This is a simple way to store datas in txt files. If you dont want to use Mysql, Mssql, SQLite etc. use this class.

Logic is simple; Your directory = Your database directory, Your files = Your tables, File contents = Table rows

#Update

• v2.0.3 - optimize io operation
• v2.0.2 - add multi condition select (search)
• v2.0.1 - optimize update method
• v2.0 - rewrite all codes and optimize the IO operation. And uses more stringent API.
• v1.7 - You can use select method with 'where' situation. Check examples.

#Usage

require("txtdb.class.php");

$db = new TxtDb();

thats it. Or;

$db = new TxtDb([
	'dir'      => 'db/',
	'extension' => 'txtdb',
	'encrypt'   => false,
]);

Encryption is used to encrypt file names.

Inserting Data

This method gets two parameters. First is "table name", second is our data in array.

$db->insert("teachers", [
	"name" => "John Doe",
	"email" => "[e-mail]"
]);

Update

This method gets three parameters. First is "table name", second is our data in array and third is "where situation"

$db->update("teachers", [
	"name" => "John Doe",
	"email" => "[e-mail]"
],1);

Delete

$db->delete("students",1);

Important : If you dont set second param, this method deletes all contents in file!

Select

This method returns array object.

 $students =  $db->select('students');
 
 foreach($students as $student){
    echo $student->name;
 }

Select One Row

This method lists one row by id

$user = $db->select('students',1);

echo $user->name;
//output
John Doe

Select with where situation

With this method you can select data with where situation, second param should be array

$teachers =$db->select('teachers',array('name' =>'Test-1'));
foreach ($teachers as $teacher) {
  echo 'Name : '.$teacher->Name.'<br>';
  echo 'Surname : '.$teacher->Surname.'<br>';
  echo 'Age : '.$teacher->Age.'<br>';
  echo 'Email : '.$teacher->Email.'<br>';
}

Easy? huh.
