Example #1 Object oriented style
<?php?
$mysqli?=?new?mysqli("127.0.0.1",?"user",?"password",?"world");?
if($mysqli->connect_error)
{
????die("$mysqli->connect_errno:?$mysqli->connect_error");
}
$query?=?"SELECT?Name,?Population,?Continent?FROM?Country?WHERE?Continent=??ORDER?BY?Name?LIMIT?1";
$stmt?=?$mysqli->stmt_init();
if(!$stmt->prepare($query))
{
????print?"Failed?to?prepare?statement\n";
}
else
{
????$stmt->bind_param("s",?$continent);
????$continent_array?=?array('Europe','Africa','Asia','North?America');
????foreach($continent_array?as?$continent)
????{
????????$stmt->execute();
????????$result?=?$stmt->get_result();
????????while?($row?=?$result->fetch_array(MYSQLI_NUM))
????????{
????????????foreach?($row?as?$r)
????????????{
????????????????print?"$r?";
????????????}
????????????print?"\n";
????????}
????}
}
$stmt->close();
$mysqli->close();
?>Example #2 Procedural style
<?php?
$link?=?mysqli_connect("127.0.0.1",?"user",?"password",?"world");?
if?(!$link)
{
????$error?=?mysqli_connect_error();
????$errno?=?mysqli_connect_errno();
????print?"$errno:?$error\n";
????exit();
}
$query?=?"SELECT?Name,?Population,?Continent?FROM?Country?WHERE?Continent=??ORDER?BY?Name?LIMIT?1";
$stmt?=?mysqli_stmt_init($link);
if(!mysqli_stmt_prepare($stmt,?$query))
{
????print?"Failed?to?prepare?statement\n";
}
else
{
????mysqli_stmt_bind_param($stmt,?"s",?$continent);
????$continent_array?=?array('Europe','Africa','Asia','North?America');
????foreach($continent_array?as?$continent)
????{
????????mysqli_stmt_execute($stmt);
????????$result?=?mysqli_stmt_get_result($stmt);
????????while?($row?=?mysqli_fetch_array($result,?MYSQLI_NUM))
????????{
????????????foreach?($row?as?$r)
????????????{
????????????????print?"$r?";
????????????}
