The date_create_immutable_from_format() function is an inbuilt function in PHP which is used to parse a time string according to the specified format.
Syntax:
- Object oriented style:
DateTimeImmutable static DateTime::createFromFormat( string $format,
string $time, DateTimeZone $timezone )
- Procedural style:
DateTimeImmutable date_create_from_format( string $format,
string $time, DateTimeZone $timezone )
Parameters: This function uses three parameters as mentioned above and described below:
- $format: This parameter holds the DateTime format in string.
- $time: This parameter holds the time in string format.
- $timezone: This parameter holds the DateTimeZone object.
Return Value: This function returns a new DateTimeImmutable object representing the date and time specified by the time string, which was formatted in the given format.
Characters and its description:
| Format character | Description | Example returned values |
|---|---|---|
| j | Day of the month without leading zeros | 1 to 31 |
| d | Day of the month with leading zeros | 01 to 31 |
| m | Numeric representation of the month | 01 to 12 |
| M | Short textual representation of the month | Jan to Dec |
| Y | Representation of a year | 1989, 2017 |
The format string can be a combination of any of the format characters in any order but we would have to provide the input date-time string in the same order.
