PHP代码中的Mysql查询不起作用

Question

Here is the code where I want to select only "tbl_name,itime_end,itime_start" above a certain date in Timestamp:

$reponse = $bdd->query('
SELECT 
tbl_name,
itime_end,
itime_start 
FROM table_ref 
WHERE `itime_start` > ".$Timestamp_UserStartDate." 
')

itime_start and $Timestamp_UserStartDate are in Timestamp

but when I do a gettype, $timestamp_USerStartDate is an integer and $itime_start is a string. An echo $timestamp_USerStartDate; gives : 1365408000 and an echo $donnees['itime_start']; gives : 1364998028 ...

The result is that all the data selected are displayed without being filtered ! Thanks in advance for your advice !

Answer 1

First off, you really shouldn't be injecting your variables the way that you're doing it. You should bind variable placeholders and then populate them later. However, the issue with your code is that you're not ending your single parenthesis the way that you're intending to. Try the line below

$reponse = $bdd->query('SELECT tbl_name,itime_end,itime_start FROM table_ref WHERE `itime_start` > "'.$Timestamp_UserStartDate.'" ')

Answer 2

If you looked at the query as it is produced, you'd see it is not what you intended.

$reponse = $bdd->query("
    SELECT 
        tbl_name,
        itime_end,
        itime_start 
    FROM table_ref 
    WHERE `itime_start` > " . $Timestamp_UserStartDate
);

will do what you expect, provided that itime_start and $Timestamp_UserStartDate both are UNIX timestamps.
