Select same column name from two tables - php

Question

I have this query:
$result3 = mysql_query("SELECT posts.id, posts.date, posts.title, comments.post, comments.id, comments.date FROM posts, comments WHERE posts.id = comments.post")
or die(mysql_error());
while($row2 = mysql_fetch_array( $result3 )) {
echo $row2['title'];
}
The problem is with the posts.id , posts.date and comments.id , comments.date . How can I get out id, date for both tables $row2['....]; I tried $row2['posts.id']; but it didn't work!

Answer 1

Name the column in your query (this is called an column alias) like this:
SELECT
posts.id as postsID,
posts.date,
posts.title,
comments.post,
comments.id as CommentsID,
comments.date
FROM
jaut_posts,
f1_comments
WHERE
jaut_posts.id = f1_comments.post
Then you can use:
echo $row2['postsID'];
echo $row2['commentsID'];
Edit:
You may also benefit from this question I wrote and answered which discusses many common SQL queries and requests.

Answer 2

Use the as in your query, some thing like
select post.id as PostId, comment.id as CommentId
and then :
row["PostId"]
row["CommentId"]

Answer 3

while($row2 = mysql_fetch_array( $result3 )) {
$post_id = $row2[0];
$posts_date = $row2[1];
$posts_title = $row2[2];
$comments_post = $row2[3];
$comments_id = $row2[4];
$comments_date = $row2[5];
}

Answer 4

change
SELECT posts.id, posts.date, posts.title, comments.post, comments.id, comments.date
into
SELECT posts.id AS postsid, posts.date, posts.title, comments.post, comments.id AS commentsid, comments.date
then you can use $row2['postsid']; and $row2['commentsid'];

Answer 5

Create alias:
$sql = 'SELECT posts.id AS post_id, comments.id AS comment_id ...';
$row = mysql_fetch_assoc($sql);
echo $row['post_id'];
echo $row['comment_id'];
or, alternatively, you can access it by indexes (since you're using mysql_fetch_array anyway)
echo $row[0]; // posts.id
