Get week number (in the year) from a date PHP

Get week number (in the year) from a date PHP

In PHP, you can use the date() function along with the W format character to get the week number of a given date in the year. Here's how you can do it:

$date = '2022-05-12'; // Example date in 'YYYY-MM-DD' format $weekNumber = date('W', strtotime($date)); echo "Week number of $date: $weekNumber";

This code will output the week number of the given date. The date() function formats the date according to the specified format string, where 'W' represents the ISO-8601 week number of the year. The strtotime() function converts the input date string into a Unix timestamp, which is then used by date() to get the week number.

Note that the week number starts from 1 and can go up to 52 or 53, depending on the year and the starting day of the week (which can be set using the date_default_timezone_set() function).
