PHP Database Obtain:

PHP Database Obtain refers to the process of retrieving data from a database using PHP programming language. In PHP, various functions and libraries are available for connecting to different database systems like MySQL, PostgreSQL, Oracle, etc. Once the connection is established, PHP functions can be used to execute queries and retrieve data from the database.

Example 1: Retrieving Data from MySQL Database

To retrieve data from MySQL database using PHP, we can use the mysqli_query() function which executes a SQL query against the database and returns the result as a mysqli_result object. Here is an example code snippet:

// Establish connection to MySQL database
$conn = mysqli_connect("localhost", "username", "password", "database_name");

// Query to retrieve data from table
$sql = "SELECT * FROM customers";

// Execute query and get result set
$result = mysqli_query($conn, $sql);

// Loop through result set and display data
while($row = mysqli_fetch_assoc($result)) {
    echo "Customer ID: " . $row["customer_id"] . "
";
    echo "Name: " . $row["name"] . "
";
    echo "Email: " . $row["email"] . "
";
}

In this example, we have established a connection to MySQL database using mysqli_connect() function and executed a SELECT query to retrieve data from the customers table. The results are then displayed using a while loop.

Example 2: Retrieving Data from MongoDB Database

To retrieve data from MongoDB database using PHP, we can use the MongoDB PHP library which provides a set of classes and functions for working with MongoDB. Here is an example code snippet:

// Establish connection to MongoDB
$client = new MongoDB\Client("mongodb://localhost:27017");

// Select database and collection
$db = $client->test_db;
$collection = $db->customers;

// Query to retrieve data from collection
$filter = [];
$options = [];

// Execute query and get cursor
$cursor = $collection->find($filter, $options);

// Loop through cursor and display data
foreach ($cursor as $document) {
    echo "Customer ID: " . $document["customer_id"] . "
";
    echo "Name: " . $document["name"] . "
";
    echo "Email: " . $document["email"] . "
";
}

In this example, we have established a connection to MongoDB database using the MongoDB PHP library and executed a find query to retrieve data from the customers collection. The results are then displayed using a foreach loop.
