Date sequence calculating

[Ron Piggott]

I am trying to calculate a date sequence using $i in conjunction with “ (so the represented # is “seen” by PHP)

The code (below) results in 2 errors:

Notice: Undefined variable: i_days_ago in /vhosts/mypainmanagementtracker.net/public/test.php on line 9
Notice: Undefined variable: i_days_ago in /vhosts/mypainmanagementtracker.net/public/test.php on line 13

<?php

$users_current_date = date('Y-m-d');
$i = 2;
while ( $i <= 10 ) {

$dt = new \DateTime( date('Y-m-d H:i:s' , strtotime( $users_current_date ) ) );
$dt->modify("-$i days");
$users_dates["$i_days_ago"]['starting_date'] = $dt->format('Y-m-d 00:00:00');

$dt = new \DateTime( date('Y-m-d H:i:s' , strtotime( $users_current_date ) ) );
$dt->modify("-$i days");
$users_dates["$i_days_ago"]['ending_date'] = $dt->format('Y-m-d 23:59:59');

++$i;
}
?>

Is there a way to do this without creating these errors and also “NOTICE” errors? The dates being calculated will be used in a database query (used to generate a report based on the activity between the starting and ending dates).

You need to concatenate the string. Right now php thinks that $i_days_ago
is a string since you have it in double quotes. You should do

$users_dates[$i . "_days_ago"]['starting_date'] = $dt->format('Y-m-d
00:00:00');
$users_dates[$i . "_days_ago"]["ending_date"] = $dt->format('Y-m-d
23:59:59');

Or you could always do:

$users_dates["{$i}_days_ago"]['starting_date'] = $dt->format('Y-m-d
00:00:00');

$users_dates["{$i}_days_ago"]['ending_date'] = $dt->format('Y-m-d
23:59:59');
