PHP: How to find multiple strpos()

Question

I have a string with the value in the format below

10:00 AM, 31 January 2017

The first task my client assigned me was to find January in that string which I have succeeded using the code below

<?php

$season_date = "10:00 AM, 31 January 2017";

if(strpos($season_date, 'January') !== false  ) {
 echo "True"; // Apply price increase percentage
}

?>

Now he has extended the task to find dates range for eg:

20 January - 02 February

How do I go about in doing this?

Edited:

I just realized my problem is bigger than the above. I actually have 2 dates

$start->format('g:i A, d F Y'); and $end->format('g:i A, d F Y');

So it's not just the matter of finding the specified string within the start and end dates, but also in between. Argh.

My final code. Thanks to everyone :)

<?php

    $daterange_season = array('2017-01-20', '2017-02-15'); /* 20 January 2017 - 15 February 2017 : Season */    
    $daterange_booked = array($book_start_date, $book_end_date);

    $range_min = new DateTime(min($daterange_season));
    $range_max = new DateTime(max($daterange_season));

    $start_book = new DateTime(min($daterange_booked));
    $end_book = new DateTime(max($daterange_booked));

    if ($start_book >= $range_min && $end_book <= $range_max) {
      echo 'Yes. Within season. Charge me!';
    } else {
      echo 'My booking is not within Peak Season, dont charge me!';
    }

?>

Simply use strtotime.

Task 1

$season_date = strtotime("10:00 AM, 31 January 2017");
echo $month=date("F",$season_date);

Task 2

$begin = new DateTime("20 January 2017");
$end = new DateTime("02 February 2017");

$interval = new DateInterval('P1D');
$daterange = new DatePeriod($begin, $interval ,$end);
// $end = $end->modify( '+1 day' );  // Uncomment this line if you want to include end date in the range.

foreach($daterange as $date){
    echo $date->format("Y-m-d") . "<br>";
}

You're looking for preg_match.

[0-9]{1,2} January

matches any string of type 2 January, 02 January or 20 January.

Thanks @TigOldBitties I think I have a bigger problem. I just realized it. I have 2 dates, $start->format('g:i A, d F Y'); and $end->format('g:i A, d F Y'); it's not just the matter of finding the date within the start and end dates, but also in between. Argh.

Regex is incredibly versatile, can help you with strings. Since you already have dates why not work with dates directly? Your question was about strings for which you can always use regex, but in this case try working directly with dates.
