pg_escape_string — Escape a string for query
Description
pg_escape_string
([ resource $connection
], string $data
) : string
pg_escape_string() escapes a string for querying the database. It returns an escaped string in the PostgreSQL format without quotes. pg_escape_literal() is more preferred way to escape SQL parameters for PostgreSQL. addslashes() must not be used with PostgreSQL. If the type of the column is bytea, pg_escape_bytea() must be used instead. pg_escape_identifier() must be used to escape identifiers (e.g. table names, field names)
Note:
This function requires PostgreSQL 7.2 or later.

connectionis not present, the default connection is used. The default connection is the last connection made by pg_connect() or pg_pconnect(). data- A string containing text to be escaped.
Return Values
