我目前正在使用 <?php
session_start();
include('includes/conexao.php');
$fileinfo=PATHINFO($_FILES["image"]["name"]);
$newFilename=$fileinfo['filename'] ."_". time() . "." . $fileinfo['extension'];
move_uploaded_file($_FILES["image"]["tmp_name"],"images/perfis/" . $newFilename);
$location="images/perfis/" . $newFilename;
$todas_fotos = mysqli_query($conexao, "select * FROM esc_usuarios_fotos WHERE img_usu_codigo = '" . $_SESSION['codigo'] . "'");
if( mysqli_num_rows($todas_fotos) > 0) {
//$path=$location;
//if(unlink($path)) echo "Deleted file ";
mysqli_query($conexao,"UPDATE esc_usuarios_fotos SET img_local = '$location' WHERE img_usu_codigo = '" . $_SESSION['codigo'] . "'");
}
else if( mysqli_num_rows($todas_fotos) == 0)
{
mysqli_query($conexao,"insert into esc_usuarios_fotos (img_local, img_usu_codigo) values ('$location', '" . $_SESSION['codigo'] . "')");
}
else {
};
header('location:perfil.php');
?>
登出该用户，但遇到一个问题，即当另一个用户重新登录时，他们能够看到其他对象数据，例如其列表或设置仍存储在从上一个用户的会话中缓存。
清除所有本地数据的最佳方法是什么，以便下一个用户获得全新的体验？
谢谢
