DateInterval::createFromDateStringSets up a DateInterval from the relative parts of the string
&reftitle.description;
&style.oop;publicstaticDateIntervalfalseDateInterval::createFromDateStringstringdatetime&style.procedural;DateIntervalfalsedate_interval_create_from_date_stringstringdatetime
Uses the date/time parsers as used in the
DateTimeImmutable constructor to create a
DateInterval from the relative parts of the parsed
string.
&reftitle.parameters;
datetime
A date with relative parts. Specifically, the relative formats supported
by the parser used for DateTimeImmutable,
DateTime, and strtotime
will be used to construct the DateInterval.
To use an ISO-8601 format string like P7D, you must
use the constructor.
&reftitle.returnvalues;
Returns a new DateInterval instance on success, &return.falseforfailure;.
&reftitle.changelog;
&Version;&Description;8.2.0
Only the from_string and
date_string properties will be visible when a
DateInterval is created with this method.
