Formatting¶

fromString( $date_string )

fromString takes a string and uses strtotime to convert it into a date object. If the string passed in is a number then it’ll convert it into an integer, being the number of seconds since the Unix Epoch (January 1 1970 00:00:00 GMT). Passing in a string of „20081231“ will create undesired results as it will covert it to the number of seconds from the Epoch, in this case „Fri, Aug 21st 1970, 06:07“

toQuarter( $date_string, $range = false )

toQuarterwill return 1, 2, 3 or 4 depending on what quarter of the year the date falls in. If range is set to true, a two element array will be returned with start and end dates in the format „2008-03-31“.

toUnix( $date_string )

toUnix is a wrapper for fromString.

toAtom( $date_string )

toAtom return a date string in the Atom format „2008-01-12T00:00:00Z“

toRSS( $date_string )

toRSS returns a date string in the RSS format „Sat, 12 Jan 2008 00:00:00 -0500“

nice( $date_string = null )

nice takes a date string and outputs it in the format „Tue, Jan 1st 2008, 19:25“.

niceShort( $date_string = null )

niceShort takes a date string and outputs it in the format „Jan 1st 2008, 19:25“. If the date object is today, the format will be „Today, 19:25“. If the date object is yesterday, the format will be „Yesterday, 19:25“.

daysAsSql( $begin, $end, $fieldName, $userOffset = NULL )

daysAsSql returns a string in the format „($field_name >= ‚2008-01-21 00:00:00‘) AND ($field_name <= ‚2008-01-25 23:59:59‘)“. This is handy if you need to search for records between two dates inclusively.

dayAsSql( $date_string,  $field_name )

dayAsSql creates a string in the same format as daysAsSql but only needs a single date object.

timeAgoInWords( $datetime_string, $options = array(), $backwards = null )

timeAgoInWords will take a datetime string (anything that is parsable by PHP’s strtotime() function or MySQL’s datetime format) and convert it into a friendly word format like, „3 weeks, 3 days ago“. Passing in true for $backwards will specifically declare the time is set in the future, which uses the format „on 31/12/08“.

relativeTime( $date_string, $format = 'j/n/y' )

relativeTime is essentially an alias for timeAgoInWords.

gmt( $date_string = null )

gmt will return the date as an integer set to Greenwich Mean Time (GMT).

format( $format = 'd-m-Y', $date_string)

format is a wrapper for the PHP date function.

Zeit-Strings testen¶

• isToday

• isThisWeek

• isThisMonth

• isThisYear

• wasYesterday

• isTomorrow

• wasWithinLast

Jede der obigen Funktionen gibt den Wert true oder false zurück, wenn eine Datum-Zeichenkette übergeben wurde. wasWithinLast hat einen weiteren Parameter $time_interval:

wasWithinLast( $time_interval, $date_string )

wasWithinLast übernimmt ein Zeit Intervall im Format „3 months“ und akzeptiert „seconds„, „minutes„, „hours„, „days„, „weeks„, „months“ und „years“ (Ein- und Mehrzahl). Wenn ein Wert nicht erkannt wird (z.B. vertippt), wird der default-Wert „days“ angenommen.
