As you can see i been trying this for a while and may have redundant parts and im getting error

#!/usr/bin/php -q
Notice: A non well formed numeric value encountered in /var/www/html/apps/calendar/cron_test.php on line 89

Can someone tell me what im doing wrong please?


I want it only to find events with and before 1 hour before event start time if its the correct year and month and day and 1 hour before event hour if this makes sense but not send if longer than an hour but less than an hour to go then email is to be sent, any ideas how to do this?

Not sure which block of code we should be looking at, but you do seem to be making heavy weather of calculating date differences 

$event_date = new DateTime('2022-05-15 15:00:00');
$now = new DateTime();
echo $event_date->diff($now)->format('%m months %d days %h hours %i minutes');     // 3 months 24 days 22 hours 34 minutes

Ok in response to that i tried
  

while($row=mysqli_fetch_array($query, MYSQLI_ASSOC)) {
$now=new DateTime();
//while($row=mysqli_fetch_array($query)){
    $SwitchID=$row["evt_id"];
    $SwitchUser=$row["username"];
    $SwitchText=$row["evt_text"];
    $evt_start=$row["evt_start"]; // $event_date
    $SwitchExpire_o=$row["evt_end"];
    $SwitchActive=$row["email_sent_status"];
   // $Timer_template=$SwitchExpire;
    //$evt_start=substr($evt_start, 0, -3);
 //   if($SwitchActive=='0'){ $switch_status='Active';}
    $SwitchExpire=strtotime($SwitchExpire_o);

    $difference=$evt_start->diff($now)->format('%m months %d days %h hours %i minutes'); // 3 months 24 days 22 hours 34 minutes
    $month=date('m',$difference);
    $days=date('d',$difference);
  //  $days=$days;
    $hours=date('h',$difference);
    $mins=date('i',$difference);
 //   $hours=$hours-12;
  //  $month=$month-1;
   // $event_date=new DateTime('2022-05-15 15:00:00');

    //$time_left=time_ago($date_time);
    $time_left=$month." Months ". $days." Days ".$hours." Hours ".$mins." Minutes";

And i cant see any output

  

echo 'Time & Date: '.$now;
echo "<p>";
echo "Event Start $evt_start";
echo "Difference: $difference";

Error

Fatal error: Uncaught Error: Call to a member function diff() on string in /var/www/html/apps/calendar/cron_test2.php:91 Stack trace: #0 {main} thrown in /var/www/html/apps/calendar/cron_test2.php on line 91

 

that line is 

$now=new DateTime();
$difference=$evt_start->diff($now)->format('%m months %d days %h hours %i minutes');

You need a datetime object when using diff(), you are using you start time string. Re-read my example 

$event_date = new DateTime($row['evt_start']);
$now = new DateTime();
$time_left = $event_date->diff($now)->format('%m months %d days %h hours %i minutes');

What were you expecting with lines like these? ... ( https://www.php.net/manual/en/function.date.php ) 

    $month=date('m',$difference);
    $days=date('d',$difference);
