(no version information, might be only in CVS)sqlite_popen -- Opens a persistent handle to an SQLite database. Will create the database if it does not exist.
Descriptionresource sqlite_popen ( string filename [, int mode [, string &error_message]])
This function behaves identically to sqlite_open() except that is uses the persistent resource mechanism of PHP. For information about the meaning of the parameters, read the sqlite_open() manual page.
sqlite_popen() will first check to see if a persistent handle has already been opened for the given filename. If it finds one, it returns that handle to your script, otherwise it opens a fresh handle to the database.
The benefit of this approach is that you don't incur the performance cost of re-reading the database and index schema on each page hit served by persistent web server SAPI's (any SAPI except for regular CGI or CLI).
