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.

 ```1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 ``` ```/*  *  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; }```

 ```1 2 3 4 5 6 7 8 9 10 11 12 13 14 ``` ```##  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```
