How to calculate the total time of an array in PHP?

Given an array containing the time in the hr: min: sec format. Problem - calculate the total time. If the total time is more than 24 hours, then the total time does not start at 0. It displays the total time. There are two ways to calculate the total time from an array.

Using the strtotime() function

Using the explode() function

Using function strtotime() : function strtotime() is used to convert string to time format. This function returns the time in h: m: s format.Syntax

strtotime (string)

Example 1 :This example reads values ​​from an array and converts them to time format.  
// Array containing the time in string format $time = [ ’ 00: 04: 35’ , ’00: 02: 06’ , ’ 01: 09: 12’ , ’09: 19: 04’ , ’00: 17: 49’ , ’02: 13: 59’ , ’10: 10: 54’ 
]; $sum = strtotime ( ’ 00: 00: 00’ ); $totaltime = 0; foreach ( $time as $element ) { // Convert time to seconds $timeinsec = strtotime ( $element ) - $sum ; // Sum the time with the previous value $totaltime = $totaltime + $timeinsec ; }  
// Totaltime is the sum of all
// time in seconds 
// Hours are obtained by dividing
// total time since 3600 $h = intval ( $totaltime / 3600); $totaltime = $totaltime - ( $h * 3600);  
// Minutes are obtained by dividing
// total time remaining since 60 $m = intval ( $totaltime / 60);  
// The rest is seconds $s = $totaltime - ( $m * 60);  
// Print result echo ( "$h: $m: $s" );  
?> Exit:

23:17 : 39

Using the function explode() : function explode() is used to split a string into an array.Syntax

 array explode (separator, string, limit)

Example 2:This example reads values ​​from an array and converts it to time format.  
// Declare an array containing times $arr = [ ’00: 04: 35’ , ’ 00: 02: 06’ , ’01: 09: 12’ , ’09: 19: 04’ , ’ 00: 17: 49’ , ’02: 03: 59’ , ’ 10: 10: 54’]; $total = 0;  
// Data element loop foreach ( $arr as $element ): // Space by delimiter: $temp = explode ( ":" , $element ); // Convert hours to seconds // and add to the total $total + = (int) $temp [0] * 3600; // Convert minutes to seconds // and add to the total $total + = (int) $temp [1] * 60; // Add seconds to total $total + = (int) $temp [2]; endforeach ;  
// Format seconds back to HH: MM: SS $formatted = sprintf ( ’% 02d:% 02d:% 02d’ , ( $total / 3600), ( $total / 60% 60), $total % 60); echo $formatted ;  
?> Exit:
