Save Postgres query in PHP variable - php

Question

I have the following Postgres query:
$sql_afect = "SELECT SUM(r.num_tiempo_afectado) FROM ctl_reportes r
WHERE 1 = 1 AND r.num_tiempo_afectado <> '00:00:00' " . (!empty($idu_clase) ?
"AND r.idu_clase = $idu_clase" : "") . " " . (!empty($idu_prioridad) ?
"AND r.idu_prioridad = $idu_prioridad" : "");
I'm working on a PHP program, and this query sums a bunch of some specific hours, which are in this format on a table (ctl_reportes): '00:00:00'.
How could I save this query's result into a PHP variable in order to echo the result on the screen?

See the code below to execute query in PHP using PDO
<?php
$user = 'root';
$pass = 'toor';
$dbh = new PDO('mysql:host=localhost;dbname=db_scrapper', $user, $pass);
$query = "SELECT SUM(r.num_tiempo_afectado) FROM ctl_reportes r
WHERE 1 = 1 AND r.num_tiempo_afectado <> '00:00:00' " . (!empty($idu_clase) ?
"AND r.idu_clase = $idu_clase" : "") . " " . (!empty($idu_prioridad) ?
"AND r.idu_prioridad = $idu_prioridad" : "");
$sth = $dbh->prepare($query);
$sth->execute();
/* Exercise PDOStatement::fetch styles */
print("PDO::FETCH_ASSOC: ");
print("Return next row as an array indexed by column name\n");
$result = $sth->fetch(PDO::FETCH_ASSOC);
var_dump($result);
Here after query is executed, the result is stored in $result. I assume you have some
basic knowledge to use PHP. Please refer to PHP PDO to have more insights into it.
Please let us know if this works for you or not. And I'll update my answer accordingly.
