pg_escape_string - Escape a string for query

SYNOPSIS
       string pg_escape_string ([resource  $connection], string  $data)

DESCRIPTION
       pg_escape_string(3)  escapes  a	string	for  querying  the database. It returns an escaped string in the PostgreSQL format without quotes.
       pg_escape_literal(3) is more preferred way to escape SQL parameters for PostgreSQL. addslashes(3) must not be used with PostgreSQL. If  the
       type  of the column is bytea, pg_escape_bytea(3) must be used instead. pg_escape_identifier(3) must be used to escape identifiers (e.g. ta-
       ble names, field names)

       Note

	       This function requires PostgreSQL 7.2 or later.

PARAMETERS
	      o $connection
		- PostgreSQL database connection resource. When $connection is not present, the default connection is used. The default connection
		is the last connection made by pg_connect(3) or pg_pconnect(3).

	      o $data
		- A string containing text to be escaped.

RETURN VALUES
	A string containing the escaped data.
