pg_tty
(PHP 3, PHP 4 )
pg_tty -- Return the tty name associated with the connection
Description
string pg_tty ( resource connection)
pg_tty() returns the tty name that server side debugging
output is sent to on the given PostgreSQL connection resource.
pg_unescape_bytea
(PHP 4 >= 4.3.0)
pg_unescape_bytea -- Unescape binary for bytea type
Description
string pg_unescape_bytea ( string data)
pg_unescape_bytea() unescapes string from bytea datatype.
It returns unescaped string (binary).
Note: When you SELECT bytea type, PostgreSQL returns octal
byte value prefixed by \ (e.g. \032). Users are supposed
to convert back to binary format by yourself.
This function requires PostgreSQL 7.2 or later. With PostgreSQL
7.2.0 and 7.2.1, bytea type must be casted when you enable
multi-byte support. i.e. INSERT INTO test_table (image)
VALUES ('$image_escaped'::bytea); PostgreSQL 7.2.2 or later
does not need cast. Exception is when client and backend
character encoding does not match, there may be multi-byte
stream error. User must cast to bytea to avoid this error.
