Thanks guys for the input. I'll check when sqlite_busy_timeout() is added to the SQLite3 in PHP5, and use PDO if it doesn't come out soon enough. ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

There's also pdo_sqlite_external which uses the sqlite3.dll the user provides, so you can use the latest and greatest sqlite version without having to wait for incorporation in PHP or PDO itself. Possible limitation: I was told pdo_sqlite_external is only available for MS Windows. -- ( Kees Nuyt ) c[_] ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

There is a patch which will make it into php 5.3.3 when it is released "very shortly" that does provide for that call. This makes the sqlite3 pretty bad for applications (such as the typical web site) where there might be some locking issues. -- Alan Chandler http://www.chandlerfamily.org.uk ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users

This is mostly fantasy, as SQL engines have widely diverging language dialects; the API is a relatively small component of interoperability pain. Still, it is a concern, and certainly a slight advantage to PDO. PDO_sqlite3 also does have the advantage of being available by default since PHP 5.0.0, whereas sqlite3 is only available by default since PHP 5.3.0. I'm aware of no other advantages to using PDO, and from what I've read it's on the slow side. -- J.

The main advantage of the PDO is that the calls for each SQL engine are identical. In other words, you can write your code as if you're going to use SQLite, then one day find you have to move to MySQL, and you'll only have to change one line of code -- the one that says which engine you want it to use. If you're in a profession where you have to use many SQL engines this can save you from having to learn the different rules and foibles of each one.

[sqlite] [PHP5-FPM] Sqlite3 or pdo_sqlite?
Hello I'm using the pre-compiled PHP5-FPM/FastCGI (www.php-fpm.org) which seem to contain the following DB connectors: PDO drivers mysql, sqlite, sqlite2 pdo_mysql 5.1.48 pdo_sqlite 3.6.22 SQLite 2.8.17 sqlite3 3.6.22 So from the above, it looks like this binary supports access to MySQL(i) and SQLite2/3, in both procedural and (PDO) object-oriented modes. If that's correct, and provided the application doesn't need to be DB-agnostic... why should I choose PDO instead of the procedural functions to SQLite3? Thank you. ___ sqlite-users mailing list sqlite-users@sqlite.org http://sqlite.org:8080/cgi-bin/mailman/listinfo/sqlite-users
