(PHP 5 >= 5.1.0, PHP 7)
pg_send_execute — Sends a request to execute a prepared statement with given parameters, without waiting for the result(s)
$connection
   , string $stmtname
   , array $params
   ) : boolSends a request to execute a prepared statement with given parameters, without waiting for the result(s).
This is similar to pg_send_query_params(), but the command to be executed is specified by naming a previously-prepared statement, instead of giving a query string. The function's parameters are handled identically to pg_execute(). Like pg_execute(), it will not work on pre-7.4 versions of PostgreSQL.
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() or pg_pconnect().
      
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(), 
       pg_send_prepare() or a PREPARE SQL
       command.
      
paramsAn 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.
Returns TRUE on success, FALSE on failure.  Use pg_get_result()
  to determine the query result.
Example #1 Using pg_send_execute()
<?php
  $dbconn = pg_connect("dbname=publisher") or die("Could not connect");
  // Prepare a query for execution
  if (!pg_connection_busy($dbconn)) {
    pg_send_prepare($dbconn, "my_query", 'SELECT * FROM shops WHERE name = $1');
    $res1 = pg_get_result($dbconn);
  }
  // Execute the prepared query.  Note that it is not necessary to escape
  // the string "Joe's Widgets" in any way
  if (!pg_connection_busy($dbconn)) {
    pg_send_execute($dbconn, "my_query", array("Joe's Widgets"));
    $res2 = pg_get_result($dbconn);
  }
  
  // Execute the same prepared query, this time with a different parameter
  if (!pg_connection_busy($dbconn)) {
    pg_send_execute($dbconn, "my_query", array("Clothes Clothes Clothes"));
    $res3 = pg_get_result($dbconn);
  }
