Calculate date difference and print these days
I would like to calculate the difference of two dates and print all dates between them, for example:
$data_inicio = new DateTime("08-02-2018");
$data_fim = new DateTime("10-03-2018");
($dateInterval = $data_inicio->diff($data_fim);
echo $dateInterval->days;
My return is : 30.
What I would like to have was the days that are in that range.
Example: 09-02-2018, 10-02-2018 ..... 09-03-2018 and etc.
How do I retrieve these values?

You can interact on the two dates with a simple for, the Class DateTime , there is a method add that can be inserted a DateInterval for a new date with a value in its Constructor P1D, i.e. one more day on the date, example:
<?php
$data_inicio = new DateTime("2018-02-08");
$data_fim = new DateTime("2018-03-10");
$dateInterval = $data_inicio->diff($data_fim);
echo $dateInterval->days;
$datas = array();
for($i = $data_inicio; $i < $data_fim; $i = $data_inicio->add(new DateInterval('P1D')) )
{
$datas[] = $i->format("d/m/Y");
}
print_r($datas);
references:
You can take a look at this class DatePeriod in the php.net:
$periodo = new DatePeriod(
new DateTime('2018-02-08'),
new DateInterval('P1D'),
new DateTime('2018-03-10')
);
It will return you an array of DateTimes.
To iterate on them:
foreach ($periodo as $key => $value) {
var_dump($value->format('d-m-Y'));
}

You can use a repeat loop. Just capture the return in days and use a for, for example:
$data_inicio = new DateTime("08-02-2018");
$data_fim = new DateTime("10-03-2018");
$dateInterval = $data_inicio->diff($data_fim);
for ($i = 1; $i < $dateInterval->days; $i++) {
/* Cria um intervalo de 1 dia */
$interval = date_interval_create_from_date_string("+1 days");
/* Adiciona esse intervalo na variável $data_inicio e imprime na tela o resultado */
echo $data_inicio->add($interval)
->format("d/M/Y"), PHP_EOL;
}

Gustavo, I believe you need to perform the following code
<?php
$d1 = '2018-02-09';
$d2 = '2018-03-09';
$timestamp1 = strtotime( $d1 );
$timestamp2 = strtotime( $d2 );
$cont = 1;
while ( $timestamp1 <= $timestamp2 )
{
echo $cont . ' - ' . date( 'd/m/Y', $timestamp1 ) . PHP_EOL;
$timestamp1 += 86400;
$cont++;
}
?>
