(PHP 5 >= 5.2.0, PHP 7, PHP 8)
date_parse — Returns associative array with detailed info about given date/time
$datetime): array
date_parse() parses the given
datetime string according to the same rules as
strtotime() and
DateTimeImmutable::__construct(). Instead of returning a
Unix timestamp (with strtotime()) or a
DateTimeImmutable object (with
DateTimeImmutable::__construct()), it returns an
associative array with the information that it could detect in the given
datetime string.
If no information about a certain group of elements can be found, these
array elements will be set to false or are missing. If needed for
constructing a timestamp or DateTimeImmutable object from
the same datetime string, more fields can be set to
a non-false value. See the examples for cases where that happens.
Returns array with information about the parsed date/time.
The returned array has keys for year,
month, day, hour,
minute, second,
fraction, and is_localtime.
If is_localtime is present then
zone_type indicates the type of timezone. For type
1 (UTC offset) the zone,
is_dst fields are added; for type 2
(abbreviation) the fields tz_abbr,
is_dst are added; and for type 3
(timezone identifier) the tz_abbr,
tz_id are added.
If relative time elements are present in the
datetime string such as +3 days,
the then returned array includes a nested array with the key
relative. This array then contains the keys
year, month, day,
hour, minute,
second, and if necessary weekday, and
weekdays, depending on the string that was passed in.
The array includes warning_count and
warnings fields. The first one indicate how many
warnings there were.
The keys of elements warnings array indicate the
position in the given datetime where the warning
occurred, with the string value describing the warning itself.
The array also contains error_count and
errors fields. The first one indicate how many errors
were found.
The keys of elements errors array indicate the
position in the given datetime where the error
occurred, with the string value describing the error itself.
The number of array elements in the warnings and
errors arrays might be less than
warning_count or error_count if they
occurred at the same position.
In case the date/time format has an error, the element 'errors' will contain the error messages.
| Version | Description |
|---|---|
| 7.2.0 |
The zone element of the returned array represents
seconds instead of minutes now, and its sign is inverted. For instance
-120 is now 7200.

Example #1 A date_parse() example with a comprehensive
datetime string
<?php
var_dump(date_parse("2006-12-12 10:00:00.5"));
?>
The above example will output:
array(12) {
["year"]=>
int(2006)
["month"]=>
int(12)
["day"]=>
int(12)
["hour"]=>
int(10)
["minute"]=>
int(0)
["second"]=>
int(0)
["fraction"]=>
float(0.5)
["warning_count"]=>
int(0)
["warnings"]=>
array(0) {
}
["error_count"]=>
int(0)
["errors"]=>
array(0) {
}
["is_localtime"]=>
bool(false)
}
The timezone elements only show up if they are included in the given
datetime string. In that case there will
always be a zone_type element and a few more depending
on its value.
Example #2 date_parse() with timezone abbreviation information
<?php
var_dump(date_parse("June 2nd, 2022, 10:28:17 BST"));
?>
The above example will output:
array(16) {
["year"]=>
int(2022)
["month"]=>
int(6)
["day"]=>
int(2)
["hour"]=>
int(10)
["minute"]=>
int(28)
["second"]=>
int(17)
["fraction"]=>
float(0)
["warning_count"]=>
int(0)
["warnings"]=>
array(0) {
}
["error_count"]=>
int(0)
["errors"]=>
array(0) {
}
["is_localtime"]=>
bool(true)
["zone_type"]=>
int(2)
["zone"]=>
int(0)
["is_dst"]=>
bool(true)
["tz_abbr"]=>
string(3) "BST"
}
Example #3 date_parse() with timezone identifier information
<?php
var_dump(date_parse("June 2nd, 2022, 10:28:17 Europe/London"));
?>
The above example will output:
array(14) {
["year"]=>
int(2022)
["month"]=>
int(6)
["day"]=>
int(2)
["hour"]=>
int(10)
["minute"]=>
int(28)
["second"]=>
int(17)
["fraction"]=>
float(0)
["warning_count"]=>
int(0)
["warnings"]=>
array(0) {
}
["error_count"]=>
int(0)
["errors"]=>
array(0) {
}
["is_localtime"]=>
bool(true)
["zone_type"]=>
int(3)
["tz_id"]=>
string(13) "Europe/London"
}
If a more minimal datetime string is parsed, less
information is available. In this example, all the time parts are returned
as false.
Example #4 date_parse() with a minimal string
<?php
var_dump(date_parse("June 2nd, 2022"));
?>
The above example will output:
array(12) {
["year"]=>
int(2022)
["month"]=>
int(6)
["day"]=>
int(2)
["hour"]=>
bool(false)
["minute"]=>
bool(false)
["second"]=>
bool(false)
["fraction"]=>
bool(false)
["warning_count"]=>
int(0)
["warnings"]=>
array(0) {
}
["error_count"]=>
int(0)
["errors"]=>
array(0) {
}
["is_localtime"]=>
bool(false)
}
Relative formats do not influence the values parsed from absolute formats, but are parsed into the "relative" element.
Example #5 date_parse() with relative formats
<?php
var_dump(date_parse("2006-12-12 10:00:00.5 +1 week +1 hour"));
?>
The above example will output:
array(13) {
["year"]=>
int(2006)
["month"]=>
int(12)
["day"]=>
int(12)
["hour"]=>
int(10)
["minute"]=>
int(0)
["second"]=>
int(0)
["fraction"]=>
float(0.5)
["warning_count"]=>
int(0)
["warnings"]=>
array(0) {
}
["error_count"]=>
int(0)
["errors"]=>
array(0) {
}
["is_localtime"]=>
bool(false)
["relative"]=>
array(6) {
["year"]=>
int(0)
["month"]=>
int(0)
["day"]=>
int(7)
["hour"]=>
int(1)
["minute"]=>
int(0)
["second"]=>
int(0)
}
}
Some stanzas, such as Thursday will set the time portion
of the string to 0. If Thursday is
passed to DateTimeImmutable::__construct() it would also
have resulted in the hour, minute, second, and fraction being set to
0. In the example below, the year element is however
left as false.
Example #6 date_parse() with side-effects
<?php
var_dump(date_parse("Thursday, June 2nd"));
?>
The above example will output:
array(13) {
["year"]=>
bool(false)
["month"]=>
int(6)
["day"]=>
int(2)
["hour"]=>
int(0)
["minute"]=>
int(0)
["second"]=>
int(0)
["fraction"]=>
float(0)
["warning_count"]=>
int(0)
["warnings"]=>
array(0) {
}
["error_count"]=>
int(0)
["errors"]=>
array(0) {
}
["is_localtime"]=>
bool(false)
["relative"]=>
array(7) {
["year"]=>
int(0)
["month"]=>
int(0)
["day"]=>
int(0)
["hour"]=>
int(0)
["minute"]=>
int(0)
["second"]=>
int(0)
["weekday"]=>
int(4)
}
