sqlite_escape_string() replaces single quotes fine (' becomes ''), whilst it fails to replace double quotes, which are still used in some odd SQL code, and which are confusing SQLite. Should there be another optional parameter selecting which quotes to escape?

Reproduce code:
$sValue = sqlite_escape_string('This string contains "double quotes"');
// Note " not ' used in this SQL statement!
$sQuery = 'INSERT INTO testtab(testfld) VALUES("' . $sValue . '")';
sqlite_query($linkID, $sQuery);

Expected result:
Successful INSERT operation

Actual result:
SQL failure

sqlite_escape_string() is just wrapper for sqlite_mprintf("%q", string) call.
In SQLite v2 this call doubles only single quotes, while in SQLite v3 it doubles ",' and \.
I don't think sqlite_escape_string() will change ever, mostly for BC reasons.
SQLite v3 is supported by pdo_sqlite.
