loop within a loop

[wazo]

Hi guys

Hope you can help me


My first loop creates the times

$StartTime = StrToTime("$start_date");
$EndTime = StrToTime("$end_date");

for($i = $StartTime; $i <= $EndTime; $i += 1 * 60 * 60){ //1 hour. I put the one so that it's easier for you to change to, say, 2 hours etc

$temp_array[] = $i;

} 

I then need to run this array against it

$check = array("08:30", "10:30"); 

and if it matches then echo a statement. The problem I have it shows every time twice like this

07:30 Add Booking
07:30 Add Booking
08:30 Match
08:30 Add Booking
09:30 Add Booking
09:30 Add Booking
10:30 Add Booking
10:30 Match
11:30 Add Booking
11:30 Add Booking
12:30 Add Booking
12:30 Add Booking
13:30 Add Booking
13:30 Add Booking
14:30 Add Booking
14:30 Add Booking
15:30 Add Booking
15:30 Add Booking
16:30 Add Booking
16:30 Add Booking

It works but shows every time twice. How can I stop this but still the matched times


Thanks in advance

What is the code you have for displaying the echo (e.g. "Match")?

I would just nest an if statement into your for loop that checks each entry in your $check array.

if you give a larger snippet of the code specifically the code that outputs the text I can help you more.

I'm guessing you're using something similar to the code below. Since in your second loop you are checking against more than one value (08:30 and 10:30), you can only use one condition, if (). You were probably using if else. The code below should work.

$start_date = '7:30';
$end_date = '16:30';
$StartTime = strtotime($start_date);
$EndTime = strtotime($end_date);

for($i = $StartTime; $i <= $EndTime; $i += 1 * 60 * 60) { //1 hour. I put the one so that it's easier for you to change to, say, 2 hours etc
  $temp_array[] = $i;
} 

$check = array('08:30', '10:30'); 

foreach ($temp_array as $time1) {

  $status = ' Add Booking';
  foreach ($check as $time2) {
    if ($time1 == strtotime($time2)) {
      $status = ' Match';
    }
  }
  print date('H:i',$time1).$status."<BR>\n";

}
