PG_EXECUTE(3)															     PG_EXECUTE(3)

pg_execute - Sends a request to execute a prepared statement with given parameters, and waits for the result.

SYNOPSIS

       resource pg_execute ([resource  $connection], string  $stmtname, array  $params)

DESCRIPTION

	Sends a request to execute a prepared statement with given parameters, and waits for the result.

       pg_execute(3) is like pg_query_params(3), but the command to be executed is specified by naming a previously-prepared statement, instead of
       giving a query string. This feature allows commands that will be used repeatedly to be parsed and planned just once, rather than each  time
       they  are  executed. The statement must have been prepared previously in the current session. pg_execute(3) is supported only against Post-
       greSQL 7.4 or higher connections; it will fail when using earlier versions.

	The parameters are identical to pg_query_params(3), except that the name of a prepared statement is given instead of a query string.

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 $stmtname
		-  The	name  of the prepared statement to execute. if "" is specified, then the unnamed statement is executed. The name must have
		been previously prepared using pg_prepare(3), pg_send_prepare(3) or a PREPARE SQL command.

	      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.

	      Warning

		      Elements are converted to strings by calling this function.

RETURN VALUES

	A query result resource on success or FALSE on failure.

EXAMPLES

       Example #1

	      Using pg_execute(3)

	      <?php
	      // Connect to a database named "mary"
	      $dbconn = pg_connect("dbname=mary");

	      // Prepare a query for execution
	      $result = pg_prepare($dbconn, "my_query", 'SELECT * FROM shops WHERE name = $1');

	      // Execute the prepared query.  Note that it is not necessary to escape
	      // the string "Joe's Widgets" in any way
	      $result = pg_execute($dbconn, "my_query", array("Joe's Widgets"));

	      // Execute the same prepared query, this time with a different parameter
	      $result = pg_execute($dbconn, "my_query", array("Clothes Clothes Clothes"));

	      ?>
