用PHP操作SQLite数据库

a、 如何连接sqlite数据库？

if ($db = sqlite_open('mysqlitedb', 0666, $sqliteerror)) {

#select * from sqlite_master;这里是查询语句代码

echo "数据库连接成功！";

} else {

die($sqliteerror);

}

b、 如何列出数据库中所有的表？

if ($db = sqlite_open('mysqlitedb', 0666, $sqliteerror)) {

$result = sqlite_array_query($db, 'select * from sqlite_master;');

foreach ($result as $entry) {

echo 'talbe name='.$entry['name']."

n";

echo 'sql='.$entry['sql']."

n";

echo "

--------------------------------------------------------------------------------

";

}

sqlite_close($db);

} else {

die($sqliteerror);

}}

c、 对sqlite数据库的查询，以及结果集的显示（select数据使用sqlite_array_query函数）

if ($db = sqlite_open('mysqlitedb', 0666, $sqliteerror)) {

#链接数据库，$db为sqlite路径，第二个语句为查询语句，第三个语句为返回结果集的格式。

$result = sqlite_array_query($db, 'select name, email from user ', SQLITE_ASSOC);

echo "user表查询结果:

n";

echo " n name email

n";

//遍历结果集

foreach ($result as $entry) {

echo ' '.$entry['name']." " $entry['email']."

n";

}

echo ' ';

sqlite_close($db);

} else {

die($sqliteerror);

}

d、数据库对象记录的增加、删除、修改（增删改数据使用sqlite_query函数执行）

sqlite_query($db, "INSERT INTO user VALUES('user".$i."'" ",'user".$i."@ hichina. com')");

sqlite_query($db, "delete from user where user=’user99’");

sqlite_query($db, 'UPDATE user SET email="lilz@ hichina .com" where name="user1"');
