/PHP-MySQLi-Database-Class

Wrapper for a PHP MySQL class, which utilizes MySQLi and prepared statements.

Primary LanguagePHP

To utilize this class, first import Mysqldbi.php into your project, and require it.


require_once('Mysqlidb.php');

After that, create a new instance of the class.


$db = new Mysqlidb('host', 'username', 'password', 'databaseName');

Next, prepare your data, and call the necessary methods.

Insert Query 



$insertData = array(
'title' => 'Inserted title',
'body' => 'Inserted body'
);


if ( $db->insert('posts', $insertData) ) echo 'success!';

Select Query 


$results = $db->get('tableName', 'numberOfRows-optional');
print_r($results); // contains array of returned rows

Update Query 


$updateData = array(
	'fieldOne' => 'fieldValue',
	'fieldTwo' => 'fieldValue'
);
$db->where('id', int);
$results = $db->update('tableName', $updateData);

Delete Query 


$db->where('id', int);
if ( $db->delete('posts') ) echo 'successfully deleted';

Generic Query Method 


$results = $db->query('SELECT * from posts');
print_r($results); // contains array of returned rows

Raw Query Method 


$params = array(3, 'My Title');
$resutls = $db->rawQuery("SELECT id, title, body FROM posts WHERE id = ? AND tile = ?", $params);
print_r($results); // contains array of returned rows

// will handle any SQL query

$params = array(10, 1, 10, 11, 2, 10);
$resutls = $db->rawQuery("
(SELECT a FROM t1 WHERE a = ? AND B = ? ORDER BY a LIMIT ?)
UNION
(SELECT a FROM t2 WHERE a = ? AND B = ? ORDER BY a LIMIT ?)
", $params);
print_r($results); // contains array of returned rows

Where Method

This method allows you to specify the parameters of the query.


$db->where('id', int);
$db->where('title', string);
$results = $db->get('tableName');
print_r($results); // contains array of returned rows

Optionally you can use method chaining to call where multiple times without referancing your object over an over:
$results = $db
->where('id', 1)
->where('title', 'MyTitle')
->get('tableName');
