Message:

Anyone could help me? I have the following fatal error:
uncaught error:
call to a member function format on string on line 89;

the line 89 is

    $monday->setISODate($days->format("o"),$days->format("W"));

my function is:

function dateToWeekPeriod($days)

{

  $monday = new DateTime();

  $monday->setISODate($days->format("o"),$days->format("W"));

  $sunday = clone $monday;

  $sunday->modify("+6 day")->setTime(23,59);



  $interval = DateInterval::createFromDateString('1 day');

  $period = new DatePeriod($monday, $interval, $sunday);

  return $period;

}

my function main is:

function main()

{

    $end = new DateTime("now");

    $begin= clone $end;

    $begin->modify('-50 days')->setTime(23,59);

    echo $end->format('Y-m-d'), "\n", $begin->format('Y-m-d')."\n";

    $interval= new DateInterval('P1D');

    $daterange= new DatePeriod($begin, $interval, $end->modify("+1 day"));



    $days=array();

    foreach($daterange as $date)

    {

      $date->format('Y-m-d')."\n";

      array_push($days,$date->format('Y-m-d'));

    }

    echo "-----les dates de l'intervalle sont:-----\n";

    var_dump($days);



    $Week=array();

    $datas=array();

    $Weeks=array();

    $insertAnnee=array();

    $recupAnnee=array();

    $tabRecupAnneeDesc=array();



    foreach($days as $d)

    {

      $week = periodToDayArray(dateToWeekPeriod($d));//les jours de la semaine concernée

      $Week=array_push($Week,$week);

    }

I have got a stack trace on this line:

$week = periodToDayArray(dateToWeekPeriod($d))

thanks in advance

My Answer:
> It looks like you are trying to call the `format()` method on a string variable `$monday`. However, the `format()` method is typically used with DateTime objects in PHP, not strings.

If you are trying to format a date string, you first need to convert it to a DateTime object using the `DateTime` class. Here's an example of how you can do that:

php
$monday = "2022-01-10"; // Assuming this is your date string
$mondayDate = new DateTime($monday);
$formattedMonday = $mondayDate->format('Y-m-d'); // Format the date as needed

echo $formattedMonday;


This code snippet will convert your date string into a DateTime object and then format it according to the specified format ('Y-m-d' in this case). Make sure to adjust the format string to match your desired output format.

If you provide more context or code snippets, I can provide more specific guidance.
