PHP - Mysql To Calendar

Hi Guys, first time poster, so I hope I have it in the right category.

I've used a program called Training Peaks for years, great program and it does cost a few $$'s. I'm also going through the Php MySQL learning curve and thought why not build something basic that I could use rather than TP.

I've been dabbling with php/mysql for a few years, nothing serious and have been looking at a few core calendar codes like Ajax, Lavarel and one built on html5. I was curious with your knowledge what might be the best way to look at this project (attachment).

In a nut shell the option to create a session (training session) it this case, it for Triathlon (swim, bike & run) ability to set a session time, date, distance and maybe some notes. TP has a lot more data that feeds from Garmin data, that's a bit over my head at the moment, so ignore TSS IF's etc

The attachment is the calendar in the back ground with the individual session open, again a lot more data there than what I need.

Google calendar was an option, but why not make it fun and learn something!

Thanks in advance.

Has anyone done this before?

i have the following VERY basic looking calendar to display the current month and <strong> on the current date;

<?php
/* Set the default timezone */
date_default_timezone_set("Europe/London");

/* Set the date */
$date = strtotime(date("Y-m-d"));

$day = date('d', $date);
$month = date('m', $date);
$year = date('Y', $date);
$firstDay = mktime(0,0,0,$month, 1, $year);
$title = strftime('%B', $firstDay);
$dayOfWeek = date('D', $firstDay);
$daysInMonth = cal_days_in_month(0, $month, $year);
/* Get the name of the week days */
$timestamp = strtotime('next Sunday');
$weekDays = array();
for ($i = 0; $i < 7; $i++) {
  $weekDays[] = strftime('%a', $timestamp);
  $timestamp = strtotime('+1 day', $timestamp);
}
$blank = date('w', strtotime("{$year}-{$month}-01"));
?>
<table class='cal-table cal-table-bordered' border=1 style='table-layout: fixed;'>
  <tr>
    <th colspan='7' class='cal-text-center'> <?php echo $title ?> <?php echo $year ?> </th>
  </tr>
  <tr>
    <?php foreach($weekDays as $key => $weekDay) : ?>
      <td class='cal-text-center"'><?php echo $weekDay ?></td>
    <?php endforeach ?>
  </tr>
  <tr class='cal-row'>
    <?php for($i = 0; $i < $blank; $i++): ?>
      <td></td>
    <?php endfor; ?>
    <?php for($i = 1; $i <= $daysInMonth; $i++): ?>
      <?php if($day == $i): ?>
	  <?php //database code here ?>
        <td><strong><?php echo $i ?></strong></td>
      <?php else: ?>
        <td><?php echo $i ?></td>
      <?php endif; ?>
      <?php if(($i + $blank) % 7 == 0): ?>
        </tr><tr class='cal-row'>
      <?php endif; ?>
    <?php endfor; ?>
    <?php for($i = 0; ($i + $blank + $daysInMonth) % 7 != 0; $i++): ?>
      <td></td>
    <?php endfor; ?>
  </tr>
</table>

how can i get data into this calendar from my 'events' table, to perhaps highlight the date of the event and show a hidden <DIV> when rollover. i have columns: 'eventStart' and 'eventEnd' and 'eventName' in the 'events' table.

or shall i look for something else? this has to be super simple with no backend or multiple files being used etc..

thanks

    Good Evening ! 
little help or a lot please ?

I have coded a calendar on my site and am now trying to input the data info from MySQL into the 
calendar by PHP for each corresponding date...the calendar code works but I cant figure out how to 
get the info that's submitted in to the specified/corresponding date in the calendar :/ but I can get 
it to the bottom of the page.

I've been at this 3 days and a million searches to find an example to follow but now I am at my wits 
end ! been about 15 years since I've done this. PLEASE help :) and thank you so much
The HTML is good I can add to it if needed but the problem area is the calendar portion and putting 
it all in the right place without an error or code issue.

I'm not sure how much more information i can provide. Like I said I am still trying to remember all 
of this stuff and trying to teach myself again and im not having much luck but i am a fast learner 
and 
can pickup by seeing how the code is written usually

Here is my code: or at least the PHP portion of it. I hope this helps.
