PHP uses PDO to connect the Sqlite3 configuration example, Pdosqlite3
This example describes how PHP uses PDO to connect sqlite3. Share to everyone for your reference, as follows:
Just started using Php+sqlite, always think that they use sqlite3, actually not, PHP php5 >=5.3.0 from the time to start the default support Sqlite3
Refer to Official Document http://www.php.net/manual/zh/sqlite3.open.php
The default method interface:
public void Sqlite3::open (string $filename [, int $flags = Sqlite3_open_readwrite | Sqlite3_open_create [, String $encryption _key]])
Using PHP to operate the database found that PHP is only supported by default to Sqlite2, the latest version of the Sqlite3 is not supported. If you want to support Sqlite3 you will use PDO. To use PDO, you need to load the Php_pdo.dll and Php_pdo_sqlite.dll two modules into the php.ini. As follows:
Extension=php_pdo.dllextension=php_pdo_sqlite.dll
If you do not use PDO, even if you open the above parameters, in fact, still use sqlite2, do not believe you access to see the generated database at the beginning of the file is not a hint:
* * This file contains an SQLite 2.1 database * *
The following error is reported when the PHP environment does not open the configuration supported above:
Fatal error:call to undefined function sqlite_open ()
sqlite3 Example:
<?php//$dsn = ' sqlite:sql.db '; try{//$dbh = new PDO ($DSN, $user, $password); Establish connection//$DBH = new PDO (' sqlite:yourdatabase.db '); $dbh = new PDO (' sqlite:itlife365.com '); Echo ' Create db OK ';//Build Table $DBH-&G T;exec ("CREATE TABLE itlife365 (ID integer,name varchar (255))"), echo ' CREATE table itlife365 OK
'; $dbh->exec ("INSERT into itlife365 values (1, ' itlife365.com ')"); Echo ' Insert Data OK
'; $dbh->begintransaction (); $sth = $dbh->prepare (' SELECT * from itlife365 '); $sth->execute ();//Get result $result = $ Sth->fetchall ();p rint_r ($result); $dsn =null;} catch (Pdoexception $e) {echo ' Connection failed: '. $e->getmessage (); $dsn = null;}? ><?php $DBH = null;//or using unset ($DBH);?>
Verify: View database:
In the file header display:
SQLite format 3***
