I'm trying to set a variable with a foreach loop, every minute.
I have this code:
$dhit = 2013-02-07 04:21:01;
$dnow= 2013-02-07 10:21:01;
$begin = new DateTime( $dhit );
$end = new DateTime( $dnow );
$interval = DateInterval::createFromDateString( '1 minute' );
$period = new DatePeriod($begin, $interval, $end);
$a = 0;
foreach ( $period as $dt ) {
$a+=1;
echo $a;
}
It works very well if $dhit is at least 24 hours old (2013-02-06 04:21:01) but not if $dhit has the same date (same day, i.e. 2013-02-07) of $dnow.
What I'm doing wrong?

Answer 1

This works for me to, i would suspect smth with your system time maybe not being set properly.
What error do you get ?
this is the test i made and it printed 1-360 as expected
<?php
$dhit = '2013-02-07 04:21:01';
$dnow= '2013-02-07 10:21:01';
$begin = new DateTime( $dhit );
$end = new DateTime( $dnow );
$interval = DateInterval::createFromDateString( '1 minute' );
$period = new DatePeriod($begin, $interval, $end);
$a = 0;
foreach ( $period as $dt ) {
$a+=1;
print "$a\n";
}

This works fine for me and prints 123456. You forgot to place quotes around your dates.
$dhit = '2013-02-07 10:15:01';
$dnow= '2013-02-07 10:21:01';
$begin = new DateTime( $dhit );
$end = new DateTime( $dnow );
$interval = DateInterval::createFromDateString( '1 minute' );
$period = new DatePeriod($begin, $interval, $end);
$a = 0;
foreach ( $period as $dt ) {
$a+=1;
echo $a; //output 123456
}
