Migrated a simple PHP – MySQL website to PHP – MongoDB

With IBM moving to MongoDB for IBM Connections in my mind, i decided to migrate one of my smallest websites from PHP – MySQL to PHP – MongoDB.

Wow, what a difference in the positive way, and how easy it is to migrate your data from MySQL into MongoDB.
You don’t need to create a database, create a table. After defining your dataset, everything is created automatically.

I created a website for my imporant dates so i cannot forget them. On this website, i created a countdowntimer for every single important date.

Migratie data from MySQL to MongoDB

For this part of the migration, i decided to write my own script.

database: datesangioni

Table into Collection: months with 2 columns: monthnumber and monthdescription

Table into Collection: dates with 7 columns: dateid, description, dateday, datemonth, dateyear, time and divname

Attention: Read my article MongoDB Change of Class

PHP MySQL database configuration

$host="localhost";
 $dbuser="<databaseuser>";
 $dbpassword="<databaseuserpassword";
 $databasename="dates";
$db = mysqli_connect($host , $dbuser, $dbpassword, $databasename);

PHP MongoDB configuration

$m = new MongoClient('mongodb://<databaseuser>:<databaseuserpassword>@<ipaddress>/datesangioni');
$db = $m->datesangioni;

PHP migration script for table months

//open collection
$collection = $db->months;
$query_read = "select * from months order by monthnumber";
$result = mysqli_query($db, $query_read);
while( $row = mysqli_fetch_array($result, MYSQLI_ASSOC) ){
$document = array(
"monthnumber" => $row['monthnumber'],
"monthdescription" => $row['monthdescription'];
);
$collection->insert($document);
}

PHP migration script for table dates

// open collection
$collection = $db->dates;
$query_read = "select * from dates";
$result = mysqli_query($db, $query_read);
while( $row = mysqli_fetch_array($result, MYSQLI_ASSOC) ){
$document = array(
"dateid"= $row['DateID'],
"description"= $row['description'],
"dateday"= $row['dateday'],
"datemonth"= $row['datemonth'],
"dateyear"= $row['dateyear'],
"time"= $row['time'],
"divname"= $row['divname'],
);
$collection->insert($document);
}
$list = $db->listCollections();

Changed PHP code from MySQL to MongoDB

/////// open database
$m = new MongoClient('mongodb://<databaseuser>:<databaseuserpassword>@<ipaddress>/datesangioni');
$db = $m->datesangioni;

/////////// read months into array
$collection = $db->months;
$cursor = $collection->find();
foreach ($cursor as $document) {
$maand[$document['monthnumber']]=$document['description'];
}

/////////// read dates into array
$collection = $db->dates;
$cursor = $collection->find();
foreach ($cursor as $document) {
$names[]=$document['description'];
$dates[]=$document['dateday'] . ' ' . $month[$document['datemonth']] . ' ' . substr('0000' . $document['dateyear'],-4);
$times[]=$document['time'];
$dvnaam[]=$document['divname'];
}

And the result is a faster and MongoDB running backend.
