Example #1 mysql_xdevapi\DocResult::getWarningsCount() example

<?php
$session 
mysql_xdevapi\getSession("mysqlx://user:password@localhost");
$session->sql("DROP DATABASE IF EXISTS addressbook")->execute();
$session->sql("CREATE DATABASE addressbook")->execute();

$schema $session->getSchema("addressbook");
$create $schema->createCollection("people");

$create->add('{"name": "Alfred", "age": 18, "job": "Butler"}')->execute();
$create->add('{"name": "Reginald", "age": 42, "job": "Butler"}')->execute();

// ...

$collection $schema->getCollection("people");

// Yields a DocResult object
$result $collection
  
->find('job like :job and age > :age')
  ->
bind(['job' => 'Butler''age' => 16])
  ->
sort('age desc')
  ->
execute();

if (!
$result->getWarningsCount()) {
    echo 
"There was an error:\n";
    
print_r($result->getWarnings());
    exit;
}

var_dump($result->fetchOne());
?>

The above example will output something similar to:

array(4) {
  ["_id"]=>
  string(28) "00005b6b53610000000000000135"
  ["age"]=>
  int(42)
  ["job"]=>
  string(6) "Butler"
  ["name"]=>

}
