Note Submitter: sxid at php dot net ---- If PHP is built with Oracle 9.2 or greater client libraries, the charset parameter is used to determine the character set used by the Oracle client libraries. When PHP is built with older Oracle client libraries, or if the parameter is not passed, Oracle NLS environment variables such as NLS_LANG will be used to determine the character set. The character set does not need to match that used by the database. If it doesn't, Oracle will do its best to convert data to and from the database character set. Depending on the character sets, this may not which may always be give usable or valid results, and it can reduce overall performance Because passing the parameter removes the environment look up, it can improve connection performance
