Formatting daily hours

[Strahan]

I have a weird issue.  I'm working on something where people will submit hours for a business.  Originally it was free form text, but then I figured it may get messy with people doing M-F 9-5 then Monday through Friday, 9AM to 5PM, Mon-Fri, etc.  So I switched to a bunch of inputs.  It has each day then a select for from and one for to.  Data is passed to the script as a form submission.  Vars are named HF# and HT# (hours from, hours to and a 0-6 digit for Mon-Sun).  I want to take the input and output a string as such:

 

Mon-Tue, 8:00 AM to 5:00 PM

Thu-Fri, 8:00 AM to 5:00 PM

Sat, 9:00 AM to 1:00 PM

Sun, 12:00 PM to 3:00 PM

 

I did this:

$formdata = array();
$formdata["hf0"] = "8:00 AM";  $formdata["ht0"] = "4:30 PM";
$formdata["hf1"] = "8:00 AM";  $formdata["ht1"] = "4:30 PM";
$formdata["hf2"] = "";         $formdata["ht2"] = "";
$formdata["hf3"] = "8:00 AM";  $formdata["ht3"] = "4:30 PM";
$formdata["hf4"] = "8:00 AM";  $formdata["ht4"] = "4:30 PM";
$formdata["hf5"] = "9:00 AM";  $formdata["ht5"] = "1:00 PM";
$formdata["hf6"] = "12:00 PM"; $formdata["ht6"] = "3:00 PM";
 
$WeekDays = array("Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun");
$hours = ""; $sd = "Mon"; $ld = ""; $fr = $formdata["hf0"]; $to = $formdata["ht0"];
for ($x=0; $x<=6; $x++) {
  if (empty($sd) && !empty($formdata["hf$x"])) { $sd = $WeekDays[$x]; $fr = $formdata["hf$x"]; $to = $formdata["ht$x"]; }
  if ($fr != $formdata["hf$x"] || $to != $formdata["ht$x"]) {
    $hours .= "$sd" . (($sd==$ld)?", ":" - $ld, ") . " $fr to $to<br/>";
    if (!empty($formdata["hf$x"])) { $sd = $WeekDays[$x]; $fr = $formdata["hf$x"]; $to = $formdata["ht$x"]; } else { $sd = ""; }
  }
  $ld = $WeekDays[$x];
}

($formdata was because I was tired of hitting back, changing the data then resubmitting)  This kinda works, but it skips Sunday.  There has got to be a better way to do this..  any ideas?

OK, I got it working.  However, I'm still curious if there is a better way to do this as my solution seems awful awkward:

$fd = array();
$fd["hf0"] = "8:00 AM";
$fd["ht0"] = "4:30 PM";
$fd["hf1"] = "8:00 AM";
$fd["ht1"] = "4:30 PM";
$fd["hf2"] = "";
$fd["ht2"] = "";
$fd["hf3"] = "9:00 AM";
$fd["ht3"] = "1:00 PM";
$fd["hf4"] = "";
$fd["ht4"] = "";
$fd["hf5"] = "9:00 AM";
$fd["ht5"] = "1:00 PM";
$fd["hf6"] = "";
$fd["ht6"] = "";

$WeekDays = array("Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun");
$hours = ""; $sd = ""; $ld = ""; $sxnt = true; $fr = ""; $to = "";

for ($x=0; $x<=5; $x++) {
  if (empty($fd["hf$x"])) {
    $hours .= "$sd" . ((empty($ld))?", ":" - $ld") . " $fr to $to<br/>{$WeekDays[$x]}, Closed<BR>"; 
    $sd = ""; $ld = "";
  } else {
    if (empty($sd)) { $sd = $WeekDays[$x]; $fr = $fd["hf$x"]; $to = $fd["ht$x"]; }
    if (empty($ld) && $sd != $WeekDays[$x]) $ld = $WeekDays[$x];
    if ($fd["hf$x"] != $fr || $fd["ht$x"] != $to) {
      $hours .= "$sd - $ld, $fr to $to<BR>";
      $sd = $WeekDays[$x]; $fr = $fd["hf$x"]; $to = $fd["ht$x"]; $ld = "";
    } else {
      if ($sd != $WeekDays[$x]) $ld = $WeekDays[$x];
    }
  }
}
if ($fd["hf6"] != $fr || $fd["ht6"] != $to) {
  $hours .= "$sd" . ((empty($ld))?", ":" - $ld") . " $fr to $to<br/>Sun, " . ((empty($fd["hf6"]))?"Closed":"{$fd["hf6"]} to {$fd["ht6"]}") . "<BR>"; 
} else {
  $hours .= "$sd - Sun, $fr to $to<BR>";
}

Which gives me:

Mon - Tue 8:00 AM to 4:30 PM
Wed, Closed
Thu, 9:00 AM to 1:00 PM
Fri, Closed
Sat, 9:00 AM to 1:00 PM
Sun, Closed

this is actually about the same logic as in your last post, but eliminates the extra code at the end to finish the last day of the week - 

<?php
$fd = array();
$fd[0] = array('f'=>"8:00 AM",'t'=>"4:30 PM");
$fd[1] = array('f'=>"8:00 AM",'t'=>"4:30 PM");
$fd[2] = array('f'=>"",'t'=>"");
$fd[3] = array('f'=>"9:00 AM",'t'=>"1:00 PM");
$fd[4] = array('f'=>"",'t'=>"");
$fd[5] = array('f'=>"9:00 AM",'t'=>"1:00 PM");
$fd[6] = array('f'=>"",'t'=>"");

$WeekDays = array("Mon", "Tue", "Wed", "Thu", "Fri", "Sat", "Sun",''); // the extra value on the end processes the last day without repeating any logic

$last_from = null; $last_to = null;
$output = '';
$last = count($WeekDays)-1;
foreach($WeekDays as $key=>$day){
if($key == $last || $last_from !== $fd[$key]['f'] || $last_to !== $fd[$key]['t']){ // it's past the end or the from/to is not-equal to last values
if($last_from !== null){ // not the first section, build the section that just ended
$end_key = $key-1;
$op = ($fd[$end_key]['f'] != '') ? "{$fd[$end_key]['f']} to {$fd[$end_key]['t']}" : 'Closed';
$dy = ($start_day == $WeekDays[$end_key]) ? $start_day : "$start_day - {$WeekDays[$end_key]}";
$output .= "$dy $op<br>";
}
// start a new section
$last_from = isset($fd[$key]) ? $fd[$key]['f'] : '';
$last_to = isset($fd[$key]) ? $fd[$key]['t'] : ''; // remember the new values
$start_day = $day;
}
}

echo $output;

the data array is organized differently to make the references clearer. you can change the form field names to submit the data as shown or change the references in the code to match your current form field names.

Thanks a lot, I'll implement your code in place of mine.  I appreciate the help
