# Compute time difference / time_since

I found this time_since function via a google search, and it works well. But I'm unsure on how to have it includes the minutes. Currently it shows X day, X hours,

function time_since(\$original) {
// array of time period chunks
\$chunks = array(
array(60 * 60 * 24 * 365 , 'year'),
array(60 * 60 * 24 * 30 , 'month'),
array(60 * 60 * 24 * 7, 'week'),
array(60 * 60 * 24 , 'day'),
array(60 * 60 , 'hour'),
array(60 , 'minute'),
);

\$today = time(); /* Current unix time */
\$since = \$today - \$original;

// \$j saves performing the count function each time around the loop
for (\$i = 0, \$j = count(\$chunks); \$i < \$j; \$i++) {

\$seconds = \$chunks[\$i][0];
\$name = \$chunks[\$i][1];

// finding the biggest chunk (if the chunk fits, break)
if ((\$count = floor(\$since / \$seconds)) != 0) {
// DEBUG print "<!-- It's \$name -->\n";
break;
}
}

\$print = (\$count == 1) ? '1 '.\$name : "\$count {\$name}s";

if (\$i + 1 < \$j) {
// now getting the second item
\$seconds2 = \$chunks[\$i + 1][0];
\$name2 = \$chunks[\$i + 1][1];

// add second item if it's greater than 0
if ((\$count2 = floor((\$since - (\$seconds * \$count)) / \$seconds2)) != 0) {
\$print .= (\$count2 == 1) ? ', 1 '.\$name2 : ", \$count2 {\$name2}s";
}
}
return \$print;
}
\$time = '1211373000';
echo time_since(\$time);

Nevermind, I'm learning :)

I simply added this to the code:

// now get the third item
\$minutes3 = \$chunks[\$i + 2][0];
\$name3 = \$chunks[\$i + 2][1];

// add third item if it's greater than 0
if ((\$count3 = floor((\$since - (\$seconds * \$count)) / \$minutes3)) != 0) {
\$print .= (\$count3 == 1) ? ', 1 '.\$name3 : ", \$count3 {\$name3}s";
}

Good good, gotta start somewhere, learning the ideas behind how things work is a great start! I always find that dates/times are a pain no matter what language you are using (if you are using manual stuff).
Once you get proficient with the manual control of the time - PHP has IMO the greatest date/time handling of any language I've used. You may want to keep this link (http://ca3.php.net/manual/en/ref.datetime.php) in mind. You will be surprised what php can do for you automatically!
