Question

<?php
function OtherDAY($start,$total){

    $date = new DateTime("$start");
    $date->add(new DateInterval('P'.$total.'D'));
    $finish=$date->format('Y-m-d');
    return $finish;

}

$start=date("Y-m-d");
$otherday=OtherDAY("$start",'15');
die($otherday);`
?>`

It is showing me “not a date format” after i kill it, how to fix this?

Answer 1

Change:

$date = new DateTime("$start");

To

$date = new DateTime($start);

And

$otherday=OtherDAY("$start",'15');

To

$otherday=OtherDAY($start,'15');

You are not passing the value of the variable in, as you are passing it in as a string
