However, if you wish to work with other databases, you must first install the relevant driver. That means, if you ever want to change one of these features, you'll have to change this class. we need to create a simple table to view results of queryyou can echo out the results directlly that convert The choice of using named or unnamed placeholders will affect how you set data for those statements.There are two steps here. It is based on some Codeigniter database methods, but my implementation, so if you could review this, that would be cool. * supports many drivers (mysql, sqlite, PostgreSQL, mssql, sybase, Oracle Call Interface -oci-) 2 \$\begingroup\$ I'm writing a simple database class so I could use it in my future projects. Despite the examples are set to work on MySQL, it can work with other types of databases. To use the class 1. Anybody can answer Of course, there may be situations where you want the constructor called before the data is assigned. mean the id column well be integer,primary key, auto increment not null, and unsigned'number' => 'int|my_constraint|other_constraint|more_constraint';SO the first one is a column type and other well be Constraintsafter insert into database you can retrieve last inserted IDnow you can check if record exist to update or create new one in easynote: $conditionColumn is optional but you need to send ID column manuallynow you can find record with custom field

* compatible with bootstrap and foundation frameworks view query results in table Lead discussions. [SQL] host = 127.0.0.1 user = root password = dbname = yourdatabase 2. the results to json formatselect(), first(), find(), paginate() methods A database class which uses the PDO extension. Typically you're only going to make a single connection - there are several listed to show you the syntax. In a previous tutorial, we have already learned about how to do database CRUD using MySQLi.

This is important. If properties matching the column names don't exist, those properties will be created (as public) for you.This means if your data needs any transformation after it comes out of the database, it can be done automatically by your object as each object is created.As an example, imagine a situation where the address needs to be partially obscured for each record.
base de données. As of PHP 5.1, there's a better way.

I assume i could put that in basic function tho, but wanted somehow to be OOP. if the table have no id set it to null. It's useful for debugging.This is the mode you should want in most situations.

Currently it can execute execute arbitrary or action queries composed from parameters that are included in prepared statements.
At the time of this writing, the following database drivers are available:All of these drivers are not necessarily available on your system; here's a quick way to find out which drivers you have:Different databases may have slightly different connection methods. However, if your array indexes are not in order, this won't work properly, and you'll need to re-index the array.You could probably guess the syntax, but here's an example:You can use a shortcut here as well, but it works with associative arrays. You can force PDO into one of three error modes by setting the error mode attribute on your newly created database handle.

PDO has you covered for this, too.Now, when you repeat the previous example with this fetch mode (PDO::FETCH_PROPS_LATE) the address will NOT be obscured, since the constructor was called and the properties were assigned.Finally, if you really need to, you can pass arguments to the constructor when fetching data into objects with PDO:If you need to pass different data to the constructor for each object, you can set the fetch mode inside the fetch method:While this isn't meant to cover everything in PDO (it's a huge extension!) Host meetups. Share ideas. "And storing username/password inside class is not a very good idea for production code." Below, the method to connect to some of the most popular databases are shown. OOP style, not procedural, i want somehow to move to OOP because you know that procedural php can get really really messy. Thanks for all suggestions, it really helps. In most situations, you're going to use the longer method so you can take advantage of prepared statements.
