PHP: Convert Minutes to Hours and Minutes (0:00)

You could use a combination of the PHP functions date() and mktime() for that conversion.

For example, in this way:

echo date('G:i', mktime(0, 97)); // 1:37
echo date('H:i', mktime(0, 97)); // 01:37

As a first parameter, mktime() takes the number of hours, as a second (optional) parameter the minutes; after that seconds, months, days and years.

When calling mktime() with mktime(0, 97), this corresponds to 0 hours and 97 minutes, which can be outputted in a custom format using date(). With using the format-string "G:i" you will get "1:37", with "H:i" "01:37", as an example.

Of course, you can also pass the number of seconds [mktime(0, 0, 120) = 120 seconds] or you can mix the arguments [mktime(1, 2, 3) = 1 hour, 2 minutes and 3 seconds]. Likewise, you can also use all of the other characters in your format string (for example "s" for seconds with leading zeros etc).

Alternatively, you can also use the function sprintf() to get the same result.

Here is an example:

$t = 97;
echo sprintf("%d:%02d",   floor($t/60), $t%60);  // 1:37
echo sprintf("%02d:%02d", floor($t/60), $t%60);  // 01:37

We pass to this function the format string as well as the values that should be replaced in the string.

In the format strings we use %d for simple integer values and %02d for integer values that are to be output with two digits using leading zeros here.

As values, we are passing floor($t/60) and $t%60. With dividing by 60 and cutting the decimal places, we get the number of hours. Accordingly, we are extracting the division remainder by calculating $t%60 in order to get the number of minutes with this.
