The ‘strtotime’ function can be used to convert the given string into a time format. Let us see an example −
Example
<?php
$time_arr = [
'00:12:56', '10:11:12', '24:12:44',
'50:51:52', '10:10:10'
];
$time = strtotime('00:00:00');
$total_time = 0;
foreach( $time_arr as $ele )
{
$sec_time = strtotime($ele) - $time;
$total_time = $total_time + $sec_time;
}
$hours = intval($total_time / 3600);
$total_time = $total_time - ($hours * 3600);
$min = intval($total_time / 60);
$sec = $total_time - ($min * 60);
print_r("The total time is :");
echo ("$hours:$min:$sec");
?>Output
The total time is :-441915:-12:-58
An array that contains time format data is defined and the ‘strtotime´function is used to convert the string into a time format. The ‘foreach’ loop is used to iterate over the elements in the time format array and the elements are added.
The hours is calculated by dividing the value computed by 3600. The minutes is calculated by dividing the value computed by product of hours calculated and 3600. The seconds is calculated by dividing the value computer by product of minutes and 60. The total time computed is displayed on the console.
