PHP-MySQL：使用特定字符限制数据

Question

I researched the forum but could not find a solution.

I have a date in my DB and date format is not like Ymd H:i . And the table is not set as date. I need to fetch the date from db but I just need Ymd . My date format like: 9.12.2014 18:34 . I just need 9.12.2014 . I want my query to stop when it sees the blank/space. I'm fine with the dmY format.

Is there a way?

Answer 1

This should account for most scenarios; you will get the whole string if there are no spaces:

SELECT IF(INSTR(field, ' ')=0, field, LEFT(field, INSTR(field, ' ')-1))
FROM the_table
;

Answer 2

I think I found the solution:

$email  = 'name@example.com';
$user = strstr($email, '@', true); // after PHP 5.3.0
echo $user; // name
