PG_SEND_QUERY_PARAMS(3) 												   PG_SEND_QUERY_PARAMS(3)

pg_send_query_params - Submits a command and separate parameters to the server without waiting for the result(s).

SYNOPSIS

       bool pg_send_query_params (resource  $connection, string  $query, array	$params)

DESCRIPTION

	Submits a command and separate parameters to the server without waiting for the result(s).

	This  is  equivalent  to  pg_send_query(3) except that query parameters can be specified separately from the $query string. The function's
       parameters are handled identically to pg_query_params(3). Like pg_query_params(3), it will not work on pre-7.4 PostgreSQL connections,  and
       it allows only one command in the query string.

PARAMETERS

	      o $connection
		- PostgreSQL database connection resource.

	      o $query
		-  The	parameterized  SQL  statement. Must contain only a single statement. (multiple statements separated by semi-colons are not
		allowed.) If any parameters are used, they are referred to as $1, $2, etc.

	      o $params
		- An array of parameter values to substitute for the $1, $2, etc. placeholders in the original prepared query string.  The  number
		of elements in the array must match the number of placeholders.

RETURN VALUES

       Returns TRUE on success or FALSE on failure.

	Use pg_get_result(3) to determine the query result.

EXAMPLES

       Example #1

	      Using pg_send_query_params(3)

	      <?php
		$dbconn = pg_connect("dbname=publisher") or die("Could not connect");

		// Using parameters.  Note that it is not necessary to quote or escape
		// the parameter.
		pg_send_query_params($dbconn, 'select count(*) from authors where city = $1', array('Perth'));

		// Compare against basic pg_send_query usage
		$str = pg_escape_string('Perth');
		pg_send_query($dbconn, "select count(*) from authors where city = '${str}'");
	      ?>

PG_ESCAPE_STRING(3)													       PG_ESCAPE_STRING(3)

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.
