PHP में दो Dates के बीच सभी Dates Array में प्राप्त करना

दो तारीखों के बीच की सभी तारीखों को array में प्राप्त करने के तरीके।

मूल फंक्शन (DateTime - अनुशंसित)

<?php
function getDatesBetween(string $startDate, string $endDate, string $format = 'Y-m-d'): array {
    $start = new DateTime($startDate);
    $end = new DateTime($endDate);
    $end->modify('+1 day'); // inclusive के लिए
    
    $dates = [];
    $interval = new DateInterval('P1D'); // 1 day
    $period = new DatePeriod($start, $interval, $end);
    
    foreach ($period as $date) {
        $dates[] = $date->format($format);
    }
    
    return $dates;
}

// उपयोग
$dates = getDatesBetween('2024-01-10', '2024-01-15');
print_r($dates);
/*
Array
(
    [0] => 2024-01-10
    [1] => 2024-01-11
    [2] => 2024-01-12
    [3] => 2024-01-13
    [4] => 2024-01-14
    [5] => 2024-01-15
)
*/

Alternative: strtotime() Loop (Legacy)

<?php
function getDatesBetweenLegacy($startDate, $endDate, $format = 'Y-m-d') {
    $dates = [];
    $current = strtotime($startDate);
    $end = strtotime($endDate);
    $step = '+1 day';
    
    while ($current <= $end) {
        $dates[] = date($format, $current);
        $current = strtotime($step, $current);
    }
    
    return $dates;
}

Generator Version (Memory Efficient)

<?php
function dateRangeGenerator(string $startDate, string $endDate, string $format = 'Y-m-d'): Generator {
    $start = new DateTime($startDate);
    $end = new DateTime($endDate);
    $end->modify('+1 day');
    
    $interval = new DateInterval('P1D');
    $period = new DatePeriod($start, $interval, $end);
    
    foreach ($period as $date) {
        yield $date->format($format);
    }
}

// उपयोग - large ranges के लिए memory efficient
foreach (dateRangeGenerator('2024-01-01', '2024-12-31') as $date) {
    // Process one by one
    echo $date . "\n";
}

// Array में convert यदि needed
$dates = iterator_to_array(dateRangeGenerator('2024-01-10', '2024-01-15'));

Business Days Only (Weekends Exclude)

<?php
function getBusinessDays(string $startDate, string $endDate, string $format = 'Y-m-d'): array {
    $dates = [];
    $start = new DateTime($startDate);
    $end = new DateTime($endDate);
    $end->modify('+1 day');
    
    $interval = new DateInterval('P1D');
    $period = new DatePeriod($start, $interval, $end);
    
    foreach ($period as $date) {
        $dayOfWeek = (int)$date->format('N'); // 1=Mon, 7=Sun
        if ($dayOfWeek < 6) { // Mon-Fri only
            $dates[] = $date->format($format);
        }
    }
    
    return $dates;
}

// Holidays exclude करने के लिए
function getBusinessDaysExcludingHolidays(string $start, string $end, array $holidays = []): array {
    $holidaySet = array_flip(array_map(fn($d) => (new DateTime($d))->format('Y-m-d'), $holidays));
    
    return array_filter(getBusinessDays($start, $end), function($date) use ($holidaySet) {
        return !isset($holidaySet[$date]);
    });
}

Custom Intervals

<?php
function getDatesWithInterval(string $start, string $end, string $intervalSpec, string $format = 'Y-m-d'): array {
    $dates = [];
    $startDt = new DateTime($start);
    $endDt = new DateTime($end);
    $endDt->modify('+1 day');
    $interval = new DateInterval($intervalSpec);
    $period = new DatePeriod($startDt, $interval, $endDt);
    
    foreach ($period as $date) {
        $dates[] = $date->format($format);
    }
    return $dates;
}

// Weekly
getDatesWithInterval('2024-01-01', '2024-02-01', 'P1W'); // Every week

// Monthly
getDatesWithInterval('2024-01-01', '2024-12-31', 'P1M'); // Every month

// Every 3 days
getDatesWithInterval('2024-01-01', '2024-01-31', 'P3D');

Carbon Library (Modern PHP Projects)

// composer require nesbot/carbon
use Carbon\CarbonPeriod;

$period = CarbonPeriod::create('2024-01-10', '2024-01-15');
$dates = $period->format('Y-m-d'); // Collection

// Business days
$businessDays = CarbonPeriod::create('2024-01-10', '2024-01-15')
    ->filter(fn($date) => $date->isWeekday())
    ->format('Y-m-d');
