Question

At the end of the following code var_dump returns bool(false) in the browser. Just wondered if somebody could spot my error given that no entry exists at all (at present) in the mysql tb = “intervals”. Cheers.

//Connection code etc

$findinterval = mysql_query("SELECT * FROM intervals ORDER BY id ASC LIMIT 1");

if($findinterval == false){
    $start_interval = "x";
} else {
    $result = mysql_fetch_array($findinterval);
    $start_interval = $result['start_interval'];
    $start_interval->modify('+1 hour');
}

if($date>=$start_interval OR $start_interval == 'x'){
    $insertinterval = mysql_query("INSERT INTO intervals VALUES ('','$date')")
    var_dump($insertinterval);

//....

Answer 1

Try this

change this:

$start_interval = $result['start_interval'];

to:

$start_interval = new DateTime($result['start_interval']);
$start_interval->modify('+1 hour');
$start_interval = $start_interval->format('Y-m-d'); // Do not forget to change this!!!
