如何在我的网站上显示查询结果

Question

so I want to show the result of my query, and I can't seem to find anything that works. this is what I have so far and I have no idea why it won't work.

daydream festival <?php
$queryday="SELECT `tickets_MAX`-`tickets_VERKOCHT` AS `tickets_over` FOR `evenementdata`        WHERE `ev id`=1";
$resultday=mysql_query($queryday);
$rowday = mysql_fetch_assoc($resultday);
echo $rowday;?> tickets left    

Answer 1

Building on other reasons why this won't print anything like your rows not existing, or misnaming things.

If I'm not mistaken mysql_fetch_assoc returns an array, echo does not print arrays. You need to use print_r($rowday); - Assuming that $rowday contains data.

Answer 2

I'm making a few assumptions here, but I think it's likely that you should do it like:

<?php
$queryday="SELECT `tickets_MAX`-`tickets_VERKOCHT` AS `tickets_over` FROM `evenementdata` WHERE `ev_id`=1";
$resultday=mysql_query($queryday);
$rowday = mysql_fetch_assoc($resultday);
print_r($rowday);
?>

That being said, I would strongly recommend not using the mysql_ functions, since they are now being depreciated. You should do some research into The PHP Data Objects (PDO) .
