Remove dates from array other than between FROM DATE and TO DATE - php

Question

I have an array in php like this
Array (
[0] => Array (
[date] => 21/07/2014
[total_booking] => 1
)
[1] => Array (
[date] => 1/08/2014
[total_booking] => 1
)
[2] => Array (
[date] => 2/09/2014
[total_booking] => 2
)
)
if i get value $_POST['from_date'] and $_POST['to_date'] all array other than between this from_date,to_date should be removed.
Edit my code
foreach ($newarray as $newarray){
if ($newarray[Date] < $to_date && $from_date > $newarray[Date])
{
// i want to remove this row from array
}
}

Here's a solution using array_filter:
<?php
$data = array(
array(
'date' => '21/07/2014',
'total_booking' => '1'
),
array(
'date' => '1/08/2014',
'total_booking' => '1'
),
array(
'date' => '2/09/2014',
'total_booking' => '2'
)
);
$from_date = strtotime('01-08-2014'); //$_POST['from_date']
$to_date = strtotime('21-08-2014'); //$_POST['to_date']
$data = array_filter($data, function($array) use ($from_date, $to_date) {
$epoch = strtotime(str_replace('/', '-', $array['date']));
return $epoch >= $from_date && $epoch <= $to_date;
});
$data = array_values($data);
print_r($data);
Output:
Array
(
[0] => Array
(
[date] => 1/08/2014
[total_booking] => 1
)
)
Only one element is outputted because only 1/08/2014 is between 1/08/2014 and 21/08/2014.
For earlier PHP versions:
function filter($array) {
$from_date = strtotime('01-08-2014'); //$_POST['from_date']
$to_date = strtotime('21-08-2014'); //$_POST['to_date']
$epoch = strtotime(str_replace('/', '-', $array['date']));
return $epoch >= $from_date && $epoch <= $to_date;
}
$data = array_filter($data, 'filter');
