How we can call store procedure in PHP ?

Create table customers  (id INT PRIMARY KEY AUTO_INCREMENT , cust_id VARCHAR(50) UNIQUE,name VARCHAR(50));

   $hostname="hostname";  // MYsql Hostname
   $db_user="username";  // Mysql Username
   $db_pwd="password";   // Mysql Password
   $db_name="databasename";  // Mysql DB name
 
   $conn=mysql_connect($hostname,$db_user,$db_pwd) or die('Database connection refused');
 
   $select_db=mysql_select_db($db_name,$conn)  or die('Database name invalid or dosen't exist'); /// databasename = your database name

include("db_connect.php"); // Check code below of the post.
 
$sql_q=mysql_query("SELECT cust_id,name FROM customers");
 
while($row_q=mysql_fetch_array($sql_q))
{
echo $row_q['cust_id'].'--'.$row_q['name'].'</br>';
}

 
DELIMITER // 
 
BEGIN
 
CREATE PROCEDURE customerName() 
 
SELECT cust_id,name  FROM customers;
 
END

include("db_connect.php");
 
$sql_q=mysql_query("CALL customerName()");
 
while($row_q=mysql_fetch_array($sql_q))
{
  echo $row_q['cust_id'].'--'.$row_q['name'].'';
}
