I wrote the following code to create a set of 12 php calendars to display specific entries from a database. I have found many posts about converting a date into an integer but can find nothing to convert an integer into a date or more specifically in this case a month. The interesting thing about all of this is that it accepts and integer as a string in a concatinated set of values initially but won't accept the $month after the change at the end of the code when it returns to continue the loop. Can anyone tell me where I'm going wrong here? <?php $month = date("m"); // Initate $month to current month $twelveCount = '1'; // Set count to 1 for loop while($twelveCount != '13') { // Create loop condition to break at 13 producing 12 calendars $monthName = date("F", strtotime($month)); // Grab name of month from $month variable $year = date("Y"); // Initiate $year from current year $firstDate = $month . '/01/' . $year; // Calculate first day of the month, NOTE: It accepts the string integer here; $firstDay = date("D", strtotime($firstDate)); // Grab day of the first date $firstDay = strtoupper($firstDay); // Capitalise first day string $lastDay = cal_days_in_month(CAL_GREGORIAN, $month, $year); // Grab last day of the month $i = '1'; // Set integer to 1 for begining of auto incremental date display $lastDayPlusOne = $lastDay + 1; // Set limit for loop break when days are complete if ($firstDay == 'SUN') {$skipDays = '0';} // Skip spaces on calendar to equal actual first day if ($firstDay == 'MON') {$skipDays = '1';} if ($firstDay == 'TUE') {$skipDays = '2';} if ($firstDay == 'WED') {$skipDays = '3';} if ($firstDay == 'THU') {$skipDays = '4';} if ($firstDay == 'FRI') {$skipDays = '5';} if ($firstDay == 'SAT') {$skipDays = '6';} $count = '0'; // Iniate $count for loop break when first day is in the correct position $calendarDisplay .= '<div style="float:left; width:182px; margin:0px 0px 7px 7px;"> <div style="float:left; width:161px; text-align:left; margin-bottom:5px;">' . $monthName .
