DB_common::quoteIdentifier()

DB_common::quoteIdentifier() -- Formats a string so it can be safely used as an identifier

Synopsis

Описание

Format input so it can be safely used as a delimited identifier in a query. Identifiers are objects such as table or column names.

The format returned depends on the database type being used.

Delimited identifiers are known to generally work correctly under the following drivers:

mssql
mysql
mysqli
oci8
odbc(access)
odbc(db2)
pgsql
sqlite
sybase

InterBase doesn't seem to be able to use delimited identifiers via PHP 4. They work fine under PHP 5.

Параметр

string $str

the input to be quoted

Возвращаемое значение

string - the formatted string

Заметка

Эта функция не должна вызываться статически.

Function available since: Release 1.6.0

Внимание

Just because you CAN use delimited identifiers doesn't mean you SHOULD use them. In general, they end up causing way more problems than they solve.

Portability is broken by using the following characters inside delimited identifiers:

backtick (`) -- due to MySQL
double quote (") -- due to Oracle
brackets ([ or ]) -- due to Access
