Here you will find PHP time and date functions to get the server time when the PHP script executes on it. These functions also allow you to get the date and time in several formats.
PHP date/time functions do not require any library to install. These functions come built-in with the PHP language.
Note: While working with the PHP date and time functions, always keep the daylight savings and leap years into consideration for the exact output. Also, server settings can affect the working of some methods.
