pg_get_result

Get asynchronous query result

Description

pg_send_query and the other asynchronous query functions can send multiple queries to a PostgreSQL server and pg_get_result is used to get each query's results, one by one.

Parameters

Return Values

The result resource, or FALSE if no more results are available.

Examples

Example #1 pg_get_result example

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

  if (!
pg_connection_busy($dbconn)) {
      
pg_send_query($dbconn"select * from authors; select count(*) from authors;");
  }
  
  
$res1 pg_get_result($dbconn);
  echo 
"First call to pg_get_result(): $res1\n";
  
$rows1 pg_num_rows($res1);
  echo 
"$res1 has $rows1 records\n\n";
  
  
$res2 pg_get_result($dbconn);
  echo 
"Second call to pg_get_result(): $res2\n";
  
$rows2 pg_num_rows($res2);
  echo 
"$res2 has $rows2 records\n";
?>

The above example will output:

First call to pg_get_result(): Resource id #3
Resource id #3 has 3 records

Second call to pg_get_result(): Resource id #4
Resource id #4 has 1 records
