date - Calculate time period list between 2 time in php? -


i want generate 3 time-period-list column between 2 times.

if $start_time = '08:00 am'; $end_time = '10:00: pm'; time period list as: morning ----- noon ----- eve 8:00 1:00 pm 6:00 pm 8:30 1:30 pm 6:30 pm 9:00 2:.0 pm 7:00 pm to ... ... ... 12:00 pm 5:00 pm 10:00 pm

i have calculated times between $start_time , $end_time as:

$time = time(); $rounded_time = $time % 900 > 450 ? $time += (900 - $time % 900): $time -= $time % 900; $start = strtotime('08:00 am'); $end = strtotime('10:00 pm'); for( $i = $start; $i <= $end; $i += 1800) { echo "<input name='start_time' type='radio' value='".date('g:i a', $i)."' />"." ".date('g:i a', $i)."<br>"; }

remaining work divide these times in 3 column mention above

thanks in advance mates.

you can use strtotime method add , substract time period given time. example:

$time = strtotime('10:00'); $halfanhourbefore = date("h:i", strtotime('-30 minutes', $time)); $halfanhourafter = date("h:i", strtotime('+30 minutes', $time));

would give $halfanhourbefore 09:30 , $halfanhourafter 10:30

Adding duplicate array rows in Php -

i create function in php adds rows of array shared column value. so input. $test = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); and output. $testduplicatefree = array( array("c", 7, 9), array("test", 5, 6) ) ); i'm thinking function combine_duplicates($array,$col){ ... ... return $duplicatefreearray; } where $col duplicate free array. so, in case, combine_duplicates($test,0); would me desired output. this. <?php function combine_duplicates($array,$col) { $index = array(); foreach ($array $row) { $key = $row[$col]; if (!isset($index[$key])) { $index[$key] = $row; } else { ($i = 0; $i < count($row); ++$i) { if ($i != $col) { $index[$key][$i] += $row[$i]; } } } } return array_values($index); } $array = array( array("c", 5, 6), array("c", 2, 3), array("test", 5, 6) ); print_r(combine_duplicates($array, 0)); try here: http://codepad.org/mdhesqhi
