PHP Forms PHP Form Handling PHP Form Validation PHP Form Required PHP Form URL/E-mail PHP Form Complete The default time zone can also be set programmatically using PHP scripts.Superglobals $GLOBALS $_SERVER $_REQUEST $_POST $_GET PHP RegEx It is also known as the UNIX timestamp.Īll PHP date() functions use the default time zone set in the php.ini file The timestamp is the number of seconds between the current time and 1 st January, 1970 00:00:00 GMT. The date function in PHP is used to format the timestamp into a human desired format. Returns two (2) digits year format (00 to 99) Returns 1 if it’s a leap year and 0 if it is not a leap year Returns the first 3 letters of the month name Returns the month number without leading zeroes Returns the month number with leading zeroes Returns the day of the year without leading spaces Returns day of the week without leading zeroes Sunday is represent by zero (0) through to Saturday represented by six (6) Returns the first 3 letters of the day name Returns the day of the month without leading zeroes Returns the day of the month with leading zeroes Returns the minutes/seconds with leading zeroes Returns the hour with leading zeros, respectively Returns the hour without leading zeroes, respectively Returns whether the current time is am or pm, AM or PM respectively The table below shows the common parameters used when working with the PHP date functions. “0,0,0” is the hour, minute and seconds respectively. Let’s now look at an example that creates a timestamp for the date using the mktime function. 1 is for DST, 0 if it is not and -1 if it is unknown. “is_dst” is optional, it is used to determine the day saving time (DST). “year” is optional, it is the number of the year “day” is optional, it is the number of the day “month” is optional, it is the number of the month “second” is optional, it is the number of seconds “minute” is optional, it is the number of minutes “hour” is optional, it is the number of hour
“mktime(…)” is the make PHP timestamp function The mktime function returns the timestamp in a Unix format. Īssuming you have saved the file set_time_zone.php in the phptuts folder, browse to the URL PHP Mktime Function It then changes the default time zone to Asia/Calcutta and displays the time again. The script below displays the time according to the default time zone set in php.ini. “string $timezone_identifier” is the time zone identifier “date_default_timezone_set()” is the function that sets the default time zone The set time zone will then be used by all date in PHP function scripts. The date_default_timezone_set function allows you to set the default time zone from a PHP script. $list)” iterates through the numeric array and prints the values.Īssuming you saved the file list_time_zones.php in phptuts folder, browse to the URL PHP set Timezone Programmatically
#PHP DATE FORMAT HOW TO#
Getting a list of available time zone identifiersīefore we look at how to set the default time zone programmatically, let’s look at how to get a list of supported time zones.
#PHP DATE FORMAT CODE#
The code below displays the current time stamp Īssuming you saved the file timestamp.php in phptuts folder, browse to the URL Note: the value of the timestamp PHP is not a constant. It can also be set programmatically using date_default_timezone_set function. The default time zone is set in the php.ini file.
The value returned by the time function depends on the default time zone. Ī timestamp in PHP is a numeric value in seconds between the current time and value as at 1 st January, 1970 00:00:00 Greenwich Mean Time (GMT). Let’s look at a basic example that displays the current year. If no timestamp has been provided, PHP will get the current PHP date time on the server. “format” is the general format which we want our output to be i.e. “date(…)” is the function that returns the current timestamp in PHP on the server.
