从结果集中取得行,然后释放结果内存:
<?php
$con=mysqli_connect("localhost","my_user","my_password","my_db");
// Check connection
if (mysqli_connect_errno($con))
{
echo "Failed to connect to MySQL: " . mysqli_connect_error();
}
$sql="SELECT Lastname,Age FROM Persons ORDER BY Lastname";
if ($result=mysqli_query($con,$sql))
{
// Fetch one and one row
while ($row=mysqli_fetch_row($result))
{
printf ("%s (%s)n",$row[0],$row[1]);
}
// Free result set
mysqli_free_result($result);
}
mysqli_close($con);
?>
mysqli_free_result() 函数释放结果内存。
mysqli_free_result(result);
