I need to convert for seconds a time received in the pattern ISO8601, used by Youtube. Someone knows some function for this purpose?

Exemplifying:

If caught by the Youtube API the length of a video PT1M31S, I’d like to convert all this just to seconds. There is a native PHP function for this? In this example the result would be 91 seconds.

    The date for many things, able to help in this case. Now, the way the question is, it forces people to research what ISO8601 is, and know what type of variable and format you’re getting the information from, and even risk giving an answer that’s not what you expect. If you [Dit] the question and put more details, it helps everyone.

PT1M31S is a time format, meaning time period of 1 minute and 31 seconds, so treat this string as a Datetime. Create a new date and add this range through the method add(), which receives as an argument Dateinterval which is exactly the string PT1M31S, done this just convert the 01:31 in seconds using date_parsed() 

$duracao = new DateTime('@0');
$duracao->add(new DateInterval('PT1M31S'));

$parsed = date_parse($duracao->format('H:i:s'));
$segundos = $parsed['hour'] * 3600 + $parsed['minute'] * 60 + $parsed['second'];

echo $segundos;

Or simply, create a Dateinterval object to translate the time period into hours/minutes/seconds and then perform the calculation to convert these values into seconds. If you use this code in several places I suggest you change the values 3600 and 60 by constants to give greater semantics, eg: const SEGUNDOS_EM_UMA_HORA = 3600 

$intervalo = new DateInterval('PT1M31S');
$segundos = $intervalo->h * 3600 + $intervalo->i * 60 + $intervalo->s; 
echo $segundos;

How to Convert a "HH:MM:SS" string to Seconds with PHP?

  • Just out of curiosity, what’s this one for '@0' in Datetime?

    @Diegofelipe server to specify a Unix timestamp, in case duration will start with 1970-01-01 00:00:00.000000 and not the local date/time. After the call from add() will change to: 1970-01-01 00:01:31.000000

Here is an example of a PHP function to convert the Youtube duration format to seconds:

function yt2seconds($youtube_time) {
   preg_match_all('/(\d+)/',$youtube_time,$parts);

   if (count($parts[0]) == 1) {
      array_unshift($parts[0], "0", "0");
   } elseif (count($parts[0]) == 2) {
      array_unshift($parts[0], "0");
   }

   $sec_init = $parts[0][2];
   $seconds = $sec_init%60;
   $seconds_overflow = floor($sec_init/60);

   $min_init = $parts[0][1] + $seconds_overflow;
   $minutes = ($min_init)%60;
   $minutes_overflow = floor(($min_init)/60);

   $hours = $parts[0][0] + $minutes_overflow;

   $conv = $hours.':'.$minutes.':'.$seconds;

   sscanf($conv, "%d:%d:%d", $hours, $minutes, $seconds);
   $time_seconds = isset($seconds) ? $hours * 3600 + $minutes * 60 + $seconds : $hours * 60 + $minutes;

   return $time_seconds;
}
