# Convert Time String (HH:MM:SS) To Seconds

Sometimes it is necessary to find the amount of seconds in a time string for use in equations. Below are PHP and Python functions to do this. These functions work by splitting the time string by ‘:’, then calculating 60 to the power of the split time count minus 1 (allowing for MM:SS format and SS format). Split time is then looped and the individual parts are multiplied by the current modifier (the previous 60^[len(split_time)-1]); the modifier is then divided by 60 for the next iteration.
==PHP==
{{{ lang=php line=1
/*
* Convert time to seconds
*
* @param Str \$time Time str (format HH:MM:SS)
*
* @return Int Amount of seconds
*/
function time_to_seconds(\$time){
\$split_time = explode(‘:’, \$time);
\$modifier = pow(60, count(\$split_time) – 1);
\$seconds = 0;
foreach(\$split_time as \$time_part){
\$seconds += (\$time_part * \$modifier);
\$modifier /= 60;
}
return \$seconds;
}
}}}
==Python==
{{{ lang=python line=1
## Convert time to seconds
#
# @param Str \$time Time str (format HH:MM:SS)
#
# @return Int Amount of seconds
import math
def time_to_seconds(time):
split_time = time.split(‘:’)
modifier = math.pow(60, len(split_time) )
seconds = 0
for time_part in split_time:
seconds += (time_part * modifier)
modifier /= 60
return seconds
}}}
