  1. Hello, Have an associative array of variable length and variable key names. The POST array can have the following structure, where [rec_n] can have one or many elements. : $_POST Array ( [rec_1769057] => on [rec_1768743] => on [ponumb] => D000000034 [strnbr] => 100 ) The 'n' is a variable SKU number and concatenated from a select statement. There are thousands of SKUs. PONUMB and STRNBR are static and will always be at the end of the array. I have an algorithm for slicing this array into two separate arrays. skuitems Array ( [rec_1769057] => on [rec_1768743] => on ) postrnbr Array ( [ponumb] => D000000034 [strnbr] => 100 ) The two arrays are then assigned to a $params array one for each update statement... $params Array ( [0] => Array ( [0] => 1768743 [1] => D000000034 [2] => 100 ) [1] => Array ( [0] => 1769057 [1] => D000000034 [2] => 100 )) I would like to accomplish the above in one go... At present the solution has and O(2) notation. Here is the algorithm that works, but seems clunky to me. if( isset($postar) && is_array($postar)) { // first order of mag. $cnt = count($postar) - 2; // total minus last two elements $postrnbr = array_slice( $postar, -2, 2 ); // always ponumb and strnbr $skuitems = array_slice($postar, 0, $cnt); // will be one or more sku items $skukeys = array_keys($skuitems); $qparams = array(); //bind params for update statement foreach($skukeys as $sku) { // second order of mag. $skusplit = explode("_",$sku); // ie Array( [0]=>rec, [1]=>1234545 ) $qparams[] = array($skusplit[1], $postrnbr['ponumb'], $postrnbr['strnbr']); } } Thanks in advance! rwhite35
  2. Hi guys, I'm trying to calculate where a future date runs in a 15 day cycle pattern, and then if the day lands on day 13 or 15 of the cycle pattern I want to do something with the result. For example: $pattern = 15; $start_date = strtotime("2015-12-14"); // day 1 // Day 15 = 2015-12-29 $chosen_date = strtotime("2016-03-30"); $difference = ($chosen_date - $start_date) / 83400; // Find which Day the 'chosen_date' comes in the sequence and... If($chosen_date == 13 || $chosen_date == 15) { Echo 'possible outcome. Day $chosen_date."; } Else { Echo 'not possible, day $chosen_date'; } Hope it makes sense! Cheers
