If you are new to PHP or just need to refresh your skills, this is the place to start. This series of tutorials will give you the basic knowledge you will need to create a simple PHP website.
PHP is a reflective programming language originally designed for producing dynamic web pages.[1] PHP is used mainly in server-side scripting, but can be used from a command line interface or in standalone graphical applications. Textual User Interfaces can also be created using ncurses.
(PHP 4, PHP 5)
odbc_foreignkeys -- Returns a list of foreign keys in the specified table or a list of foreign keys in other tables that refer to the primary key in the specified tableodbc_foreignkeys() retrieves information about foreign keys. Returns an ODBC result identifier or FALSE on failure.
The result set has the following columns:
PKTABLE_QUALIFIER
PKTABLE_OWNER
PKTABLE_NAME
PKCOLUMN_NAME
FKTABLE_QUALIFIER
FKTABLE_OWNER
FKTABLE_NAME
FKCOLUMN_NAME
KEY_SEQ
UPDATE_RULE
DELETE_RULE
FK_NAME
PK_NAME
If pk_table contains a table name,
odbc_foreignkeys() returns a result set
containing the primary key of the specified table and all of the
foreign keys that refer to it.
If fk_table contains a table name,
odbc_foreignkeys() returns a result set
containing all of the foreign keys in the specified table and the
primary keys (in other tables) to which they refer.
If both pk_table and
fk_table contain table names,
odbc_foreignkeys() returns the foreign keys in
the table specified in fk_table that refer
to the primary key of the table specified in
pk_table. This should be one key at most.
