strftime - PHP code example

PHP Function Strftime

The php function strftime is a more advanced version of the date function that allows for more customized formatting. It takes two parameters: a format string and a timestamp. The format string can contain a variety of different specifiers that represent different parts of the date and time. This function is also more flexible in terms of how it can format time zones and month names.

In addition to the usual format specifiers, strftime supports an extensive list of charset conversion specifiers. This can be useful when working with different languages or when dealing with characters that are not in the default (US) charset.

It is important to note that not all of the available conversion specifiers may be supported by your C library, in which case they will not be supported by strftime. It is also worth mentioning that not all platforms support negative timestamps, which means that dates prior to the Unix epoch may not work on all systems.

The php function strftime returns a string that is formatted according to the given $format string using the given timestamp, or the current local time if no timestamp is provided. Month and weekday names and other language dependent strings respect the current locale set with setlocale(). If the format string is empty or contains unsupported conversion specifiers, it will return a false value.
