PHP Date & Time Function Manual
The date_interval_create_from_date_string() function builds a DateInterval from the relevant part of the string.
date_interval_create_from_date_string()Function isDateInterval :: createFromDateStringalias. This accepts a string specifying the interval and returns a DateInterval object.
date_interval_create_from_date_string($time)
Number | Parameters and Description |
---|---|
1 | time (required) This is a string value specifying the relative format in which you want to output the date string/Interval. |
date_interval_create_from_date_string() returns a DateInterval object representing the given interval value.
This function was originally introduced in PHP version5.3introduced and can be used in all higher versions.
The following example demonstratesdate_interval_create_from_date_string()Usage of the function-
<?php $time = "3year + 3months + 26 day + 12 hours+ 30 minutes +23 seconds"; $interval = date_interval_create_from_date_string($time); print_r($interval); ?>Test see‹/›
Output results
DateInterval Object ( [y] => 3 [m] => 3 [d] => 26 [h] => 12 [i] => 30 [s] => 23 [f] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 )
In this function, you cannot use ISO8601strings (e.g. " P12M”)to parse such intervals, you need to useDateIntervalconstructor.
In the following example, we use the ISO8601String representation of the interval-
<?php $time1 = new DateInterval('P25DP8MP9Y'); print_r($time1); $time2 = new DateInterval('PT10H'); print_r($time2); ?>Test see‹/›
Output results
DateInterval Object ( [y] => 9 [m] => 8 [d] => 25 [h] => 0 [i] => 0 [s] => 0 [f] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 ) DateInterval Object ( [y] => 0 [m] => 0 [d] => 0 [h] => 10 [i] => 0 [s] => 0 [f] => 0 [weekday] => 0 [weekday_behavior] => 0 [first_last_day_of] => 0 [invert] => 0 [days] => [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 0 [have_special_relative] => 0 )
The following examples add time intervals to the current date and print the results. Here, we usedate_interval_create_from_date_stringfunction to calculate time intervals.-
<?php $date = date_create(); $str = "12year 3months 14days"; $interval = date_interval_create_from_date_string($str); $res1 = date_add($date, $interval); print("Date after ".$str); print(": ".date_format($res1, 'Y-m-d')); ?>Test see‹/›
Output results
Date after 12year 3months 14days: 2032-08-28
The following examples use various ISO8601String and their respective regular string creation date intervals-
<?php print(new DateInterval('P12D')."\n"); print(DateInterval::createFromDateString('12 day')."\n"); print(new DateInterval('P7')."\n"); print(DateInterval::createFromDateString('7 months')."\n"); print(new DateInterval('P12Y')."\n"); print(DateInterval::createFromDateString('12 years')."\n"); print(new DateInterval('PT9H')."\n"); print(DateInterval::createFromDateString('9 hours')."\n"); print(new DateInterval('PT19i')."\n"); print(DateInterval::createFromDateString('19 minutes')."\n"); print(new DateInterval('PT45S')."\n"); print(DateInterval::createFromDateString('45 seconds')."\n"); ?>
