may be called immediately.

Example 3.92 Object oriented style
<?php /* Open a connection */ $mysqli = new mysqli("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20"; if ($stmt = $mysqli->prepare($query)) { /* execute query */ $stmt->execute(); /* store result */ $stmt->store_result(); printf("Number of rows: %d.\n", $stmt->num_rows); /* close statement */ $stmt->close(); } /* close connection */ $mysqli->close(); ?>
Example 3.93 Procedural style
<?php /* Open a connection */ $link = mysqli_connect("localhost", "my_user", "my_password", "world"); /* check connection */ if (mysqli_connect_errno()) { printf("Connect failed: %s\n", mysqli_connect_error()); exit(); } $query = "SELECT Name, CountryCode FROM City ORDER BY Name LIMIT 20"; if ($stmt = mysqli_prepare($link, $query)) { /* execute query */ mysqli_stmt_execute($stmt); /* store result */ mysqli_stmt_store_result($stmt); printf("Number of rows: %d.\n", mysqli_stmt_num_rows($stmt)); /* close statement */ mysqli_stmt_close($stmt); } /* close connection */ mysqli_close($link); ?>
The above examples will output:
