Php obtains the start and end dates of the week and last week.

Recently, due to work needs, php is used to obtain the start date and end date of the current week and last week. I found it online, but it was not suitable. So I made a summary myself. The specific content and Code are as follows.

<? Phpheader ('content-type: text/html; charset = UTF-8 '); $ date = date ('Y-m-d'); // current date $ first = 1; // $ first = 1 indicates that Monday is the start date 0, indicating that every Sunday is the start date $ w = date ('w', strtotime ($ date )); // obtain the day of the current week. The day from Sunday is 0 Monday to Saturday is 1-6 $ now_start = date ('Y-m-d', strtotime ("$ date -". ($ w? $ W-$ first: 6 ). 'Days '); // obtain the start date of the week. If $ w is 0, it indicates Sunday, minus 6 days $ now_end = date ('Y-m-d ', strtotime ("$ now_start + 6 days"); // end date of the week $ last_start = date ('Y-m-d ', strtotime ("$ now_start-7 days"); // last week's start date $ last_end = date ('Y-m-d ', strtotime ("$ now_start-1 days"); // last week end date echo 'start date of the week: ', $ now_start,' <br/> '; echo 'end date of the week: ', $ now_end,' <br/> '; echo 'start date of the last week:', $ last_start, '<br/> '; echo 'end Date of last week: ', $ last_end,' <br/> ';

Note: Since the weeks in foreign countries start from Sunday and China is used to start from Monday, an error occurs when strtotime ("last Monday") is used directly.
