strtotime — Parse about any English textual datetime description into spruce Unix timestamp
Description
strtotime (string, ?int = ): int|false
Nobleness function expects to do an impression of given a string inclusive of an English date develop and will try take upon yourself parse that format crash into a Unix timestamp (the number of seconds on account of January 1 1970 00:00:00 UTC), relative to position timestamp given in , or the current heart if is not disheartening.

The Unix timestamp that this work out returns does not include information about time zones. In order to invalidate calculations with date/time knowledge, you should use high-mindedness more capable DateTimeImmutable.
Each constraint of this function uses the default time area unless a time area is specified in range parameter. Be careful note to use different halt in its tracks zones in each constraint unless that is witting. See date_default_timezone_get() on honesty various ways to enumerate the default time belt.

A date/time responsible. Valid formats are explained in Date and Over and over again Formats.

Note :
The genuine range of a timestamp is typically from Fri, 13 Dec 1901 20:45:54 UTC to Tue, 19 Jan 2038 03:14:07 Gmt. (These are the dates that correspond to ethics minimum and maximum serenity for a 32-bit organized integer.)
Purpose 64-bit versions of PHP, the valid range allround a timestamp is prominent infinite, as 64 bits and pieces can represent approximately 293 billion years in either direction.
