PHP while loop adding 1 day to each date for 4 dates?

Question

I'm trying to loop through and add cells to an HTML table, starting with a start date and adding one day to the start date with each iteration for 4 loops:

$DayCount = 0;

while ($DayCount < 5) {

echo "<td>";
echo date('m/d/Y', strtotime('+$DayCount days', strtotime($UpWeekStart)));
echo "</td>";

$DayCount = $DayCount + 1;

}

Is my syntax wrong? $UpWeekStart is a PHP variable containing user-selected date.

Answer 1

Use " instead of ':

echo date('m/d/Y', strtotime("+$DayCount days", strtotime($UpWeekStart)));

Single quoted strings will display things almost completely "as is." Variables and most escape sequences will not be interpreted. Whereas double quote strings will evaluate the variables in the string. See this answer for more details.

Answer 2

Remember your loop is starting at zero, and you are stopping it at 4 i.e. < 5, thats 5 iterations. Plus use double quotes around $variables you want expanded as in strtotime("+$DayCount days", strtotime($UpWeekStart)

So try

$DayCount = 0;

while ($DayCount < 4) {

    echo "<td>";
    echo date('m/d/Y', strtotime("+$DayCount days", strtotime($UpWeekStart)));
    echo "</td>";

    $DayCount = $DayCount + 1;

}
