pg_escape_identifier — Escape a identifier for insertion into a text field

Açıklama

string pg_escape_identifier ([ resource $connection ], string $data )

pg_escape_identifier() escapes a identifier (e.g. table, field names) for quering the database. It returns an escaped identifier string for PostgreSQL server. pg_escape_identifier() adds double quotes before and after data. Users should not add double quotes. Use of this function is recommended for identifier parameters in query. For SQL literals (i.e. parameters except bytea), pg_escape_literal() or pg_escape_string() muse be used. For bytea type fields, pg_escape_bytea() must be used instead.

Bilginize:
This function has internal escape code and can also be used with PostgreSQL 8.4 or less.
