php+mysql怎么查詢本周的數(shù)據(jù)
思路：先關(guān)聯(lián)數(shù)據(jù)庫，然后執(zhí)行sql語句，最后返回結(jié)果！
需要關(guān)聯(lián)上數(shù)據(jù)庫
?php
//創(chuàng)建對象并打開連接，最后一個參數(shù)是選擇的數(shù)據(jù)庫名稱
$mysqli?=?new?mysqli('localhost','root','','volunteer');
//檢查連接是否成功
if?(mysqli_connect_errno()){
//注意mysqli_connect_error()新特性
die('Unable?to?connect!').?mysqli_connect_error();
}
$sql?=?"SELECT?*FROM?表名?where?DATE_SUB(CURDATE(),?INTERVAL?7?DAY)?=?date(時間字段名)";
//執(zhí)行sql語句，完全面向?qū)ο蟮?/p>
$result?=?$mysqli-query($sql);
while($row?=?$result-fetch_array()){
echo?$row[0];
}
?
執(zhí)行一條sql語句
SELECT?*FROM?表名?where?DATE_SUB(CURDATE(),?INTERVAL?7?DAY)?=?date(時間字段名)
3.運行結(jié)果、返回結(jié)果集：
$result=mysql_query($query);
并對結(jié)果進行處理！
php如何獲取數(shù)據(jù)庫里上一周的數(shù)據(jù)？
echo date('Y-m-d',strtotime ( "last Monday -1 week" )), "\n" ;
echo date('Y-m-d',strtotime ( "last Sunday" )), "\n" ;
通過這個函數(shù)獲取上個周的開始和結(jié)束，然后sql查詢
可以研究下這個函數(shù)strtotime 。可以滿足你的需求
如何用PHP 獲取今天之前,本周之前,本月之前,本年之前,今天,本周,本月,本年的數(shù)據(jù)呢
/*今天*/
select?*?from?表名?where?to_days(時間字段)?=?to_days(now());
/*昨天*/
select?*?from?表名?where?to_days(now())-to_days(時間字段)?=?1;
/*近7天*/
select?*?from?表名?where?date_sub(curdate(),?interval?7?day)?=?date(時間字段);
/*查詢距離當(dāng)前現(xiàn)在6個月的數(shù)據(jù)*/
select?*?from?表名?where?時間字段?between?date_sub(now(),interval?6?month)?and?now();
/*查詢當(dāng)前這周的數(shù)據(jù)*/
select?*?from?表名?where?yearweek(date_format(時間字段,'%Y-%m-%d'))?=?yearweek(now());
/*查詢上周的數(shù)據(jù)*/
select?*?from?表名?where?yearweek(date_format(時間字段,'%Y-%m-%d'))?=?yearweek(now())-1;
/*查詢當(dāng)前月份的數(shù)據(jù)*/
select?*?from?表名?where?date_format(時間字段,'%Y-%m')=date_format(now(),'%Y-%m');
/*查詢上個月的數(shù)據(jù)*/
select?*?from?表名?where?date_format(時間字段,'%Y-%m')=date_format(date_sub(curdate(),?interval?1?month),'%Y-%m');
其它獲取類似以上的代碼顯示
