How to query records from today in a database using PHP?

To search for records from today in the database, you can use MySQL’s date functions to filter out the relevant records.

Assuming your database table name is “records” and it has a datetime field called “created_at”, you can use the following code to query records for the current day:

// 获取当前日期
$currentDate = date("Y-m-d");

// 构建SQL查询语句
$sql = "SELECT * FROM records WHERE DATE(created_at) = '$currentDate'";

// 执行查询
$result = mysqli_query($connection, $sql);

// 遍历结果
while ($row = mysqli_fetch_assoc($result)) {
    // 输出记录的字段值
    echo $row['field1'] . ' ' . $row['field2'] . ' ' . $row['field3'] . '<br>';
}

Please remember to substitute ‘records’ with your table name, and ‘created_at’ with your date time field. Additionally, make sure to appropriately establish database connection and handle the results according to your specific situation.

This code section will retrieve the current date and construct an SQL query statement to filter out records where the created_at field date is equal to the current date. It will then execute the query using mysqli_query, iterate through the result set using mysqli_fetch_assoc, and output the field values of the records.

I hope this is helpful for you!
