Description
   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.
