                                  sqlite_open

   (no version information, might be only in CVS)
   sqlite_open -- Opens a SQLite database. Will create the database if it
   does not exist

Description

   resource sqlite_open ( string filename [, int mode [, string
   &error_message]])

   Returns a resource (database handle) on success, FALSE on error.

   The filename parameter is the name of the database. It can be a
   relative or absolute path to the file that sqlite will use to store
   your data. If the file does not exist, sqlite will attempt to create
   it. You MUST have write permissions to the file if you want to insert
   data or modify the database schema.

   The mode parameter specifies the mode of the file and is intended to
   be used to open the database in read-only mode. Presently, this
   parameter is ignored by the sqlite library. The default value for mode
   is the octal value 0666 and this is the recommended value to use if
   you need access to the errmessage parameter.

   errmessage is passed by reference and is set to hold a descriptive
   error message explaining why the database could not be opened if there
   was an error.

   Example 1. sqlite_open() example
   <?php
   if ($db = sqlite_open('mysqlitedb', 0666, $sqliteerror)) {
       sqlite_query($db, 'CREATE TABLE foo (bar varchar(10))');
       sqlite_query($db, "INSERT INTO foo VALUES ('fnord')");
       $result = sqlite_query($db, 'select bar from foo');
       var_dump(sqlite_fetch_array($result));
   } else {
       die($sqliteerror);
   }
   ?>

     Tip: On Unix platforms, SQLite is sensitive to scripts that use the
     fork() system call. If you do have such a script, it is recommended
     that you close the handle prior to forking and then re-open it in
     the child and/or parent. For more information on this issue, see
     The C language interface to the SQLite library in the section
     entitled Multi-Threading And SQLite.

     Tip: It is not recommended to work with SQLite databases mounted on
     NFS partitions. Since NFS is notoriously bad when it comes to
     locking you may find that you cannot even open the database at all,
     and if it succeeds, the locking behaviour may be undefined.

     Note: Starting with SQLite library version 2.8.2, you can specify
     :memory: as the filename to create a database that lives only in
     the memory of the computer. This is useful mostly for temporary
     processing, as the in-memory database will be destroyed when the
     process ends. It can also be useful when coupled with the ATTACH
     DATABASE SQL statement to load other databases and move and query
     data between them.

     Note: SQLite is safe mode and open_basedir aware.
