PHP Function Accessing Database Connection

Question

How do I allow a function to access a database connection without using GLOBAL?

config.php

 DEFINE (\'DB_HOSTNAME\', \'hostname\');
 DEFINE (\'DB_DAT         


        

Answer 1

its so simple just pass your $conn variable into another calling function(instead of making new connection) like

yourpage.php

$conn = new mysqli($servername, $username, $password, $dbname);
someFunction ($conn)//you can add other parameters if you like 

function someFunction ($conn) {
    $result = mysqli_query ($conn, "SELECT * FROM examples);
}

Note:This is not good practice to always make new connection for database access.so always make connection once and use it every where.(but if your requirement different and require multiples connections then you can make multiples connections)
