for($i=1;$i<=$day;$i++){

}

output will be like this

Thursday 21st of July 2016
Friday 22st of July 2016
       23st of July 2016
       24st of July 2016
       25st of July 2016
       26st of July 2016
       27st of July 2016
       28st of July 2016
       29st of July 2016
       30st of July 2016
       31st of July 2016
       1st of August 2016

try my edited code.

$day=$row['db_day'];

$start_day = strtotime(date("Y-m-d"));
$end_day = $start_day + 86400 * $day;

    while($end_day >= $start_day){
            echo date("j F, Y",$start_day)."
";
            $start_day = $start_day + 86400;
    }

I hope its helps

<?php
$date = date('Y-m-d');
$end_date = date('Y-m-d', strtotime('+9 days')); //add the num of days u need here
while (strtotime($date) <= strtotime($end_date)) {
       echo "<pre>".$date = date ("Y-m-d", strtotime("+1 day", strtotime($date)));
 }

You could use the Datetime class and it's associated methods

/* formats for dates */
$df='Y-m-d H:i:s';
$dfo='l jS \of F, Y';

/* variable, number of days from NOW */
$days=14;

/* set the timezone and date interval */
$timezone=new DateTimeZone('Europe/London');
$interval=new DateInterval('P1D');

/*establish date range */
$ts=date( $df, strtotime('yesterday') );
$tf=date( $df, strtotime('1st August 2016') );

/* Alternatively... */
$tf=date( $df, strtotime('now +'.$days.' days') );


/* create instances of the `Datetime` class for both dates */
$start=new DateTime( $ts, $timezone );
$end=new DateTime( $tf, $timezone );

/* show the dates in the range */
while( $start->add( $interval ) <= $end ){
    echo $start->format( $dfo ). '<br />';
}

Will output:
