First of all you are going to want to change your $datesAvailableArray<\/code> so that it contains an actual dates.
\nISO 8601<\/a> strings are an excellent format.<\/p>\n

$datesAvailableArray = array(\n    'Saturday' => array(\n        '2014-11-14T11:00:00Z',\n        '2014-11-14T12:00:00Z',\n        '2014-11-14T13:00:00Z',\n        '2014-11-14T14:00:00Z'\n    ),\n    'Sunday' => array(\n        '2014-11-15T11:00:00Z',\n        '2014-11-15T12:00:00Z',\n        '2014-11-15T13:00:00Z',\n        '2014-11-15T14:00:00Z'\n    )\n);\n<\/code><\/pre>\n
Now that we have date strings we can create DateTime objects that we use to format the date:<\/p>\n
$saturday_1100 = DateTimeImmutable::createFromFormat(DateTime::ISO8601, '2014-11-14T11:00:00Z');\n$saturday_1100->format('g:ia'); \/\/ 11:00am\n<\/code><\/pre>\n
In our case we are using the DateTimeImmutable class<\/a> since we don’t want to change the dates after they are created.<\/p>\n
So lets change our makeTable<\/code> function to use our new friend DateTimeImmutable<\/code>:<\/p>\n
function makeTable($data) {\n\n    $headers = array_map(function($a) {\n        return \"<th>$a<\/th>\";\n    }, array_keys($data));\n\n    $max_indice = max( array_map(function($day) {\n        return count($day) - 1;\n    }, $data) );\n\n    \/\/ Create a new array where we group by hour\n    $rows = array_map(function($i) use ($data) {\n        \/\/ create each hour\n        return '<tr>' . join( array_map(function($day) use ($i){\n            $ts = isset($day[$i]) ? DateTimeImmutable::createFromFormat(DateTime::ISO8601, $day[$i]) : null;\n            if ($ts){\n                $label=\"<label for=\"datetime\">\".$ts->format('g:ia').'<\/label>';\n                $input = vsprintf ( \n                    '<input type=\"checkbox\" name=\"datetime\" id=\"%s\" value=\"%s\" \/>',\n                    array(\n                        'datetime_'. $ts->getTimestamp(), \/\/ ID\n                        $ts->format('c')  \/\/ Value\n                    )\n                );\n                return '<td>' . $label . $input . '<td>';\n            } else {\n                return '<td><\/td>';\n            }\n        }, $data)) . '<\/tr>';\n    }, range(0, $max_indice));\n\n    \/\/ Don\u00b4t get rid of the thead element. \n    \/\/ It tells the browser that your table is a real table containing data and not just a crappy layout.\n    return \"\n    <table>\n        <caption>My Table<\/caption>\n        <thead>\".join($headers,'\\n').\"<\/thead>\n        <tbody>\".join($rows, '\\n').\"<\/tbody>\n    <\/table>\";\n}\n<\/code><\/pre>\n
echo makeTable( $datesAvailableArray );<\/code> Will give us something like this:<\/p>\n
<table>\n  <caption>\n    My Table\n  <\/caption>\n\n  <thead>\n    <tr>\n      <th>Saturday<\/th>\n      <th>Sunday<\/th>\n    <\/tr>\n  <\/thead>\n\n  <tbody>\n    <tr>\n      <td><label for=\"datetime\">11:00am<\/label><input type=\"checkbox\" name=\"datetime\" id=\"datetime_1415962800\" value=\"2014-11-14T11:00:00+00:00\" \/><\/td>\n      <td><label for=\"datetime\">11:00am<\/label><input type=\"checkbox\" name=\"datetime\" id=\"datetime_1416049200\" value=\"2014-11-15T11:00:00+00:00\" \/><\/td>\n    <\/tr>\n    <tr>\n      <td><label for=\"datetime\">12:00pm<\/label><input type=\"checkbox\" name=\"datetime\" id=\"datetime_1415966400\" value=\"2014-11-14T12:00:00+00:00\" \/><\/td>\n      <td><label for=\"datetime\">12:00pm<\/label><input type=\"checkbox\" name=\"datetime\" id=\"datetime_1416052800\" value=\"2014-11-15T12:00:00+00:00\" \/><\/td>\n    <\/tr>\n    <!-- MORE ... -->\n  <\/tbody>\n<\/table>\n<\/code><\/pre>\n
Summary:<\/p>\n
We have unique values for the input id. The value that we send when posting this form is a ISO-8601 date string.
\nWe also have wrapped our hour text in <label><\/code> tags with a for attribute which is good for accessibility.<\/p>\n<\/p><\/div>\n
