On the day of query by php and mysql, this week is queried to query the data instance of this month (the field is a timestamp)

// Where video is the table name; // createtime is the field; // The database time field is the timestamp /// query Date: $ start = date ('Y-m-d 00:00:00 '); $ end = date ('Y-m-d H: I: s '); SELECT * FROM 'table _ name' WHERE 'time'> = unix_timestamp ('$ start') AND 'time' <= unix_timestamp (' $ end') // query this week: SELECT yearweek ('2014-04-17 15:38:22 ', 1) // The result is 2011 SELECT yearweek ('2014-04-17 15:38:22 ') // The result is 201116 // The reason why the 2nd parameter of yearweek is set to 1 is that the Chinese people are used to taking week 1 as the first day of the week. // Add: // Yes Sunday. SELECT dayofweek ('2014-04-17 15:38:22 ') // the query result is 1, and the day of the week is regarded as the first day of the week.

SELECT * FROM 'table _ name' where yearweek (FROM_UNIXTIME ('time', '% Y-% m-% d % H: % I: % s'), 1) = YEARWEEK (now (), 1) // query this month: $ start = date ('Y-m-01 00:00:00 '); $ end = date ('Y-m-d H: i: s'); SELECT * FROM 'table _ name' WHERE 'time'> = unix_timestamp ('". $ start.

Php obtains the start Timestamp and end time of today, yesterday, last week, and this month.

<? Php // <! -- Php obtains the start and end timestamps of today, yesterday, last week, and this month. It mainly uses the php time function mktime (). --> // 1. php obtains the start Timestamp and end timestamp of today $ beginToday = mktime (0, 0, date ('M'), date ('D '), date ('y'); $ endToday = mktime (0, 0, 0, date ('M'), date ('D') + 1, date ('y ')) -1; echo $ beginToday. '---'. $ endToday; echo '<br/>'; // 2. php obtains the start and end timestamps of yesterday. $ beginYesterday = mktime (, 0, 0, date ('M'), date ('D')-1, date ('y'); $ endYesterday = mktime (0, 0, date ('M '), date ('D'), date ('y')-1; echo $ beginYesterday.

'---'. $ endThismonth; echo '<br/>'; // PHP mktime () function is used to return the Unix timestamp of a date. // Syntax: mktime (hour, minute, second, month, day, year, is_dst) /// parameter description // hour is optional. The specified hour. // Optional. Minutes. // Second is optional. Specified seconds. // Month is optional. Indicates the month in number. // Day is optional. Specified day. // Year is optional. Specified year. In some systems, the valid value ranges from 1901 to 2038. However, this restriction does not exist in PHP 5. // Is_dst is optional. If the time is in the daylight saving time (DST) period, it is set to 1; otherwise, it is set to 0. If it is unknown, it is set to-1. // The is_dst parameter has been deprecated since 5.1.0. Therefore, the new time zone processing feature should be used. The parameter always represents the GMT date, so is_dst has no effect on the result. //// The parameters can be left empty from right to left. The blank parameters are set to the corresponding GMT value. Echo (date ("M-d-Y", mktime (2002,); // The output result is as follows: // Jan-05-

On the day of the above php and mysql query, this week, the query of the data instance for this month (the field is a timestamp) is all the content shared by the editor, I hope to give you a reference, we also hope that you can support the customer's home.
