Example 20.163. 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); ?>
