PHP date_interval_create_from_date_string() Function
The PHP date_interval_create_from_date_string() function uses the normal date parsers and sets up a DateInterval from the relative parts of the parsed string. This function is an alias of DateInterval::createFromDateString() method.
Syntax
//Object-oriented style public DateInterval::createFromDateString(datetime) //Procedural style date_interval_create_from_date_string(datetime)
Parameters
datetime |
Required. Specify a date with relative parts. Specifically, the relative formats supported by the parser used for strtotime() and DateTime will be used to construct the DateInterval. |
Return Value
Returns a new DateInterval instance on success, or false on failure.
Example: using both styles
The example below shows the usage of date_interval_create_from_date_string() function.
<?php //creating a DateTime object $date1 = date_create("10-Mar-2015 5:10:25"); $date2 = date_create("10-Mar-2015 5:10:25"); //datetime string $datetime_str = "2 years 5 months 10 days 5 hours 35 minutes"; //creating a date interval from date string //string using object-oriented style $interval1 = DateInterval::createFromDateString($datetime_str); date_add($date1, $interval1); echo date_format($date1, 'd-M-Y H:i:s')."\n"; //creating a date interval from date string //string using Procedural style $interval2 = date_interval_create_from_date_string($datetime_str); date_add($date2, $interval2); echo date_format($date2, 'd-M-Y H:i:s')."\n"; ?>
The output of the above code will be:
20-Aug-2017 10:45:25 20-Aug-2017 10:45:25
Example: using different relative formats
Consider one more example where some more relative formats are used.
<?php $interval11 = date_interval_create_from_date_string("last year"); print_r($interval11); echo "\n"; $interval12 = date_interval_create_from_date_string("next week"); print_r($interval12); ?>
The output of the above code will be:
DateInterval Object ( [y] => -1 [m] => 0 [d] => 0 [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] => 7 [h] => 0 [i] => 0 [s] => 0 [f] => 0 [weekday] => 1 [weekday_behavior] => 2 [first_last_day_of] => 0 [invert] => 0 [days] => [special_type] => 0 [special_amount] => 0 [have_weekday_relative] => 1 [have_special_relative] => 0 )
