## Example

`

     resource pg_query_params ([ resource $connection ], string $query , array $params )

`

## Description

Submits a command to the server and waits for the result, with the ability to pass parameters separately from the SQL command text. pg_query_params() is like pg_query(), but offers additional functionality: parameter values can be specified separately from the command string proper. pg_query_params() is supported only against PostgreSQL 7.4 or higher connections; it will fail when using earlier versions. If parameters are used, they are referred to in the query string as $1, $2, etc. params specifies the actual values of the parameters. A NULL value in this array means the corresponding parameter is SQL NULL. The primary advantage of pg_query_params() over pg_query() is that parameter values may be separated from the query string, thus avoiding the need for tedious and error-prone quoting and escaping. Unlike pg_query(), pg_query_params() allows at most one SQL command in the given string. (There can be semicolons in it, but not more than one nonempty command.)

## Return Values

A query result resource on success or FALSE on failure.
