To connect to Amazon Redshift using PHP, you will need to use the PHP PostgreSQL library. This library provides functions that allow you to connect to PostgreSQL databases, such as Amazon Redshift.
The following is an example of how to connect to a Redshift database using PHP:
<?php
$host = "examplecluster.cluster-cxz123.us-east-1.redshift.amazonaws.com";
$port = "5439";
$dbname = "dev";
$credentials = "awsuser";
$pg_conn = pg_connect("host=$host port=$port dbname=$dbname user=$credentials");
if (!$pg_conn) {
echo "Error : Unable to open database\n";
} else {
echo "Opened database successfully\n";
}
?>
