让mySQL date_format在PHP中显示

Question

This could sound like a very simple question to many of you, but I seem to be having trouble getting a basic date_format to work with my mySQL statement and then to be displayed using php. Here is the code that I currently have:

$result = mysql_query("SELECT *, DATE_FORMAT('timestamp', '%W %D %M %Y') as date FROM articleDB WHERE userID='".$_SESSION["**"]."' ORDER BY timestamp DESC LIMIT 8");

Then trying to display it using:

echo ' Posted: '.$row['timestamp'].''; 

All I want is to format the date from a PHP myAdmin timestamp to the format I want.

Cheers

Answer 1

Use backticks ( `` ) or nothing at all instead of single-quotes ( '`) around your field in your query:

$result = mysql_query("SELECT *, DATE_FORMAT(`timestamp`, '%W %D %M %Y') as date FROM articleDB WHERE userID='".$_SESSION["**"]."' ORDER BY timestamp DESC LIMIT 8");

Backticks ( `` ) creates a reference to a table member, single-quotes creates a string ( ' ). You were basically trying to ). You were basically trying to DATE_FORMAT the string 'timestamp'` instead of the field.

Also, since you are using as to create a field alias, you want to refer to that field using the alias when outputting:

echo ' Posted: '.$row['date'];

Answer 2

您需要在select语句中显示您计算/格式化的“日期”列，时间戳列包含未格式化的原始日期值。

echo ' Posted: '.$row['date'];

Answer 3

因为在您的SQL查询中，您将日期格式定义as date您通过$row['date']访问它$row['date'] 。
