Script work on different servers

[magpie]

There is a violin:

<meta http-equiv="content-type" content="text/html; charset=UTF-8" />
<?php

$mysqli =mysqli_connect('---', '---', '---', '---');

if (mysqli_connect_errno()) {

echo "Failed to connect to MySQL: ".mysqli_connect_error();

}

$result = $mysqli->query('SELECT * FROM climat');

$rows = array();

$table = array();

$table['cols'] = array(

array('label' => 'date', 'type' => 'string'),

array('label' => 't_in', 'type' => 'number')

);

foreach($result as $r) {
 $temp = array();
 $temp[] = array('v' =&gt; (string) $r['date']); 
 $temp[] = array('v' =&gt; (float) $r['t_in']); 
 $rows[] = array('c' =&gt; $temp);
}

$table['rows'] = $rows;
$jsonTable = json_encode($table);

echo $jsonTable;

?>

On one PHP server, Version 5.6.11, mysql 5.6.27 works.
And on another PHP server Version 5.3.21, mysql 5.5.28 is not working.
No data.

How can this problem be addressed?

@Alexei-Shiman ' s rights should be determined when choosing a procedural or objective style.

The following is the condom(s) and the rest will be rewritten by yourself. http://php.net/manual/ru/mysqli.quickstart.stored-procedures.php ♪

P.S. To make it clear what it is, the code must be in such a way:

instead $r['date'] - Category $r->date etc.

$mysqli = new mysqli('localhost', 'my_user', 'my_password', 'my_db');
if ($mysqli->connect_error) {
    die('Ошибка подключения (' . $mysqli->connect_errno . ') '
        . $mysqli->connect_error);
}
