  Valid options  
  Name Description
MYSQLI_STORE_RESULT_COPY_DATA Copy results from the internal mysqlnd buffer into the PHP variables fetched. By default, mysqlnd will use a reference logic to avoid copying and duplicating results held in memory. For certain result sets, for example, result sets with many small rows, the copy approach can reduce the overall memory usage because PHP variables holding results may be released earlier (available with mysqlnd only, since PHP 5.6.0)

mysqli_stmt_init(connection);

Parameter:

Name Description Required/Optional
connection Specifies the MySQL connection to use Required

Return value:

Returns a buffered result object or FALSE if an error occurred..

Version: PHP 5, PHP 7

Example:

<?php
$con=mysqli_connect("localhost","user1","datasoft123","hr");
// Check connection
if (mysqli_connect_errno())
  {
  echo "Failed to connect to MySQL: " . mysqli_connect_error();
  }

$city="Paris";

// Create a prepared statement
$stmt=mysqli_stmt_init($con);

if (mysqli_stmt_prepare($stmt,"SELECT District FROM city WHERE Name=?"))
  {

  // Bind parameters
  mysqli_stmt_bind_param($stmt,"s",$city);

  // Execute query
  mysqli_stmt_execute($stmt);

$const1 = "EARTH_IS_FLAT";
$const2 = "APP_ENV_UPPERCASE";
if (constant($const1)) {
 print "Earth is flat";
}
