I'm developing a website for specific EVENTS. Each EVENT lasts for three months and has fixed start date and end date, and they repeat each year: Event 1: Jan. 1st – Mar. 31st Event 2: Apr. 1st – Jun. 30th Event 3: Jul. 1st – Sep. 30th Event 4: Oct. 1st – Dec. 31st I have two functions FUNCTION 1: should run 3 days before start of the event. FUNCTION 2: should run 1 day before start of last month of the event. Functions should execute only that specific event and not other future or past events. Here how the functions should run for each Event: Event 1: Jan. 1st – Mar. 31st Function 1: on Dec 29 Function 2: last day of Feb Event 2: Apr. 1st – Jun. 30th Function 1: on Mar 29 Function 2: last day of May Event 3: Jul. 1st – Sep. 30th Function 1: on Jun 28th Function 2: Last day of Aug Event 4: Oct. 1st – Dec. 31st Function 1: on Sept 28th Function 2: last day of Nov What I'm doing right now is checking today's date and comparing it to the event date. If event start date is > today and event start date < 3 then run function one. My problem/questions: As of now, I have to remember to execute the functions manually on a specific date. How can I make this automated? Can I execute the function using server Cron job? Will that be a good practice? How would you approach in checking the event date to today? I feel there maybe better way of checking the date to run the function instead of what I'm doing. I hope my question is not vague and makes sense. Thank you.

I am trying to convert colors from Hex to HSL (Not HSL to Hex). I am using a PHP function for this purpose. But It's not working properly for some colors. For example for #e04c4c the HSL should be (0, 70%, 59%) which it isn't the case with the function. function hexToHsl($hex) { $red = hexdec(substr($hex, 0, 2)) / 255; $green = hexdec(substr($hex, 2, 2)) / 255; $blue = hexdec(substr($hex, 4, 2)) / 255; $cmin = min($red, $green, $blue); $cmax = max($red, $green, $blue); $delta = $cmax - $cmin; if ($delta === 0) { $hue = 0; } elseif ($cmax === $red) { $hue = (($green - $blue) / $delta) % 6; } elseif ($cmax === $green) { $hue = ($blue - $red) / $delta + 2; } else { $hue = ($red - $green) / $delta + 4; } $hue = round($hue * 60); if ($hue < 0) { $hue += 360; } $lightness = (($cmax + $cmin) / 2) * 100; $saturation = $delta === 0 ? 0 : ($delta / (1 - abs(2 * $lightness - 1))) * 100; if ($saturation < 0) { $saturation += 100; } $lightness = round($lightness); $saturation = round($saturation); //return "hsl(${hue}, ${saturation}%, ${lightness}%)"; return array($hue, $saturation, $lightness); } This is how I used it: $templatePrimaryColor = '#e04c4c'; $templatePrimaryColor = str_replace("#", "",$templatePrimaryColor); list($h,$s,$l) = hexToHsl($templatePrimaryColor); $primaryColor = "hsl(${h}, ${s}%, ${l}%)"; This is the output: echo '<pre>',print_r(hexToHsl($templatePrimaryColor)).'</pre>'; Array ( [0] => 0 [1] => 99 [2] => 59 ) 1 Does anyone know what is the problem there? Thank you.

Hi, I've inherited some code on a system from another person. I'll be the first to admit that I'm not a PHP pro, I am self taught, and use it sparingly for personal projects mainly. So this is a bit beyond my skill level, and I was hoping for some advice: The system is a glorified calendar, with a lot of our own data being slapped on top of it and presented nicely. The issue I have thoguh is that due to the way the calendar is generated, I cant make the height of the days move dynamically based on what content gets dropped into each day on the calendar. If one day is busy and has 8 events drop into it, they will overflow the days cell. I wanted to adjust the height of ALL cells on a month view calendar to the heighest required height of all cells in that view. What I was going to do, is +1 to a coutner for every event (or block) that is generated for each day (days are looped through a private function), and commit that number to an array. At the end fo the loop (after all days ahve been counted and have a value in the array), I was going to use max() on the array, pull the largest number, calculate the days cell hiehgt from that and apply it via CSS at page level. I've summarised the code in effect here (psuedo code, not real PHP): class Calendar { public $heights; private fucntion dayLoop($cellNumber) { $heights = []; //array $block_count = 0; //counter while(mysqlrowdata) { [code for mysql operations] $block_count++; //increment the count } $day_height = ($block_count * 16) + 18; //do some math specific to my application $this->heights[] = $day_height; //commit calc'd value to array //array_push($heights, $day_height); //this was a previosu attempt, i dont think i should use array_push here..?? } } That function, and others is called from the front end pages to generate the calendar. If I do a: var_dump($heights); after it on that page, all I get returned on screen is "Array ( )" I tried changing the private function to a public one, but this did not affect the outcome. Anyone have any ideas on what I'm doing wrong? Is my logic sound? Can I commit values to an array inside a loop in a public OR private function and then reference that array outside of the loop? I defined $heights as public in the class too, but that didnt change the outcome either. Thanks.

Say I have this records table. RECORDS TABLE record_id | sponsor_id | user_id | plan_id ------------------------------------------------------------------------------ 1 user5 user6 5 // I am this user. 2 user3 user5 3 3 user3 user4 4 4 user2 user3 4 5 user2 user2 2 6 user0 user1 5 I am "user6" and my sponsor is "user5". What I want to do is find the same "plan_id" from my sponsors, no matter how far up I have to do. For eg. My current plan id is "5". My sponsor is "user5". If I look for "user5" in the user_id column, I would find that he only has plan "3" id. So I go to his sponsor, which is "user3" and find him in the user_id column. That user's plan id is "4" so it does not match my plan id either. I repeat the same process by going to his sponsor and his sponsor and so on until I find the plan id that matches me. So for this table example, that would be "user1". I only want to retrieve the first result that matches my plan id. How do I go on about coding this function? Normally I can do these queries to go up limited amount. But I am looking for a more proper function that lets me search my sponsors unlimited times. $find_plan_id = $db->prepare("SELECT sponsor_id, plan_id FROM records WHERE user_id = :user_id"); $find_plan_id->bindParam(':user_id', $user_id); $find_plan_id->execute(); $result_find_plan_id = $find_plan_id->fetchAll(PDO::FETCH_ASSOC); if(count($result_plan_id) > 0) { foreach($result_plan_id as $row) { $get_sponsor_id_1 = $row['sponsor_id']; $get_plan_id_1 = $row['plan_id']; } if($get_plan_id_1 == $my_plan_id) { echo 'Plan id matches.'; } else { $find_plan_id_2 = $db->prepare("SELECT sponsor_id, plan_id FROM records WHERE user_id = :user_id"); $find_plan_id_2->bindParam(':user_id', $get_sponsor_id_1); $find_plan_id_2->execute(); $result_plan_id_2 = $find_plan_id_2->fetchAll(PDO::FETCH_ASSOC); if(count($result_plan_id_2) > 0) { foreach($result_plan_id_2 as $row) { $get_sponsor_id_2 = $row['sponsor_id']; $get_plan_id_2 = $row['plan_id']; } if($get_plan_id_2 == $my_plan_id) { echo 'Plan id matches.'; } else { // repeat the process } } } }
