|
||
|
|
* With this method you are assigning day, hour, minute and second
|
||
|
|
* values, and the last values are used. This means that if you use
|
||
|
|
* something like:
|
||
|
|
*
|
||
|
|
* <code>$object->setFromString('10, 20', '%H, %h');</code>

* your time span would be 20 hours long. Always remember that this
|

|
* method sets all the values, so if you had a span object 30
|
||
|
|
* minutes long and you call:
|

|

*
|
||
|
|
* <code>$object->setFromString('20 hours', '%H hours');</code>

|

|
|
* minutes).

*

|
|
* - <b>%C</b> - Days with time, equivalent to '<b>D, %H:%M:%S</b>'

* - <b>%n</b> - Newline character (\n)
|
