Extracting dates from date range

Question

Part of my answer was answered by dynamic: How to extract every Monday and every fortnightly Monday from a range of two dates in PHP?

I've added a foreach loop to print all the mondays in this example:

$start = strtotime('2016-09-05');
$end = strtotime('2016-09-30');

$mondays=array(); 
$tuesdays=array();  

while( $start <= $end  ) {

if ( date('N',$start)==1 )   
$mondays[]=$start;
$start += 86400;  

}  
foreach ($mondays as $item) {  
print date("D. Y-m-d", ($item)); 
print ("<br>");
}

and i get these results: enter image description here

But how do i add an else/if statements to display the tuesdays for example

if the date begins with $start = strtotime('2016-09-06');

I want it to show: enter image description here

Thanks.

If you want loop the same days of week as the 1 day `$start = strtotime('+1 week', $start); ` — splash58, Sep 10 '16 at 21:00
@splash58 I believe they want to add a day, not a week. This is what I take from seeing their screenshots. — Funk Forty Niner, Sep 10 '16 at 21:06

In keeping with your current approach:

$start = strtotime('2016-09-05');
$end = strtotime('2016-09-30');

while($start <= $end) {
    if(date("D", $start) == "Mon"){
        $mondays[] = $start;
    }
    elseif(date("D", $start) == "Tue"){
        $tuesdays[] = $start;
    }
    $start += 86400;
}

foreach ($mondays as $item){
    echo date("D. Y-m-d", $item);
    echo "<br>";
}

echo "<br>";

foreach ($tuesdays as $item){
    echo date("D. Y-m-d", $item);
    echo "<br>";
}

In this code, we first find the DayOfWeek, and then find all dof in range:

// Data

$StartDate = strtotime('2016-09-06');
$EndDate   = strtotime('2016-09-30');

$DayOfWeek = date("l", $StartDate); // Determine day of week

$LoopDate = $StartDate;

// Find all DayOfWeek's Between Start and End

$Result = [$StartDate];

while (true) {
    $NextDayOfWeek = strtotime("next " . $DayOfWeek, $LoopDate);

    if ($NextDayOfWeek > $EndDate) {
        break;
    }

    $Result[] = $LoopDate = $NextDayOfWeek;
}

// Print Result

/**
 | 2016-09-06
 | 2016-09-13
 | 2016-09-20
 | 2016-09-27
 */
foreach( $Result as $Row ) {
    echo date("Y-m-d", $Row) . '<br/>';
}

Glad to hear that, enjoy – MoeinPorkamel Sep 10 '16 at 21:48 — MoeinPorkamel, Sep 10 '16 at 21:48
