Test script:
---------------
<?php

$host = '';
$port = '';// 5432
$db   = '';
$user = '';
$pass = '';

$connectString = "host=$host port=$port dbname=$db user=$user password=$pass";
$pg_pconnect = pg_pconnect($connectString);

$string63 = '5c6b58ebdd4464734a57a87431ba24b38d2e49ae5c6b58ebdd4464734a57a87';// length - 63
//$string63 = 'smallLengthSQL';// Uncomment for expected result.

$sqlPreparedNameA = $string63 . '_A';// length - 65 for error case.
$sqlPreparedNameB = $string63 . '_B';// length - 65 for error case.
$sqlPreparedBodyA = 'SELECT $1 as result_1'                ;
$sqlPreparedBodyB = 'SELECT $1 as result_1, $2 as result_2';

$pg_prepareA = pg_prepare($pg_pconnect, $sqlPreparedNameA, $sqlPreparedBodyA);
$pg_prepareA = pg_prepare($pg_pconnect, $sqlPreparedNameB, $sqlPreparedBodyB);

$pg_executeA = pg_execute($pg_pconnect, $sqlPreparedNameA, array("Result A1"             ));
$pg_executeB = pg_execute($pg_pconnect, $sqlPreparedNameB, array("Result B1", "Result B2"));

$resultA     = pg_fetch_all($pg_executeA);
$resultB     = pg_fetch_all($pg_executeB);

var_dump($resultA);
var_dump($resultB);

Expected result:
----------------
array(1) {
  [0]=>
  array(1) {
    ["result_1"]=>
    string(9) "Result A1"
  }
}
array(1) {
  [0]=>
  array(2) {
    ["result_1"]=>
    string(9) "Result B1"
    ["result_2"]=>
    string(9) "Result B2"
  }
}
