Echo返回数组而不是值

Question

My echo returns Array instead of value.

$postscount = mysql_query('select count(authorid) from topics where authorid="'.$author.'" ');
$posts = mysql_fetch_row($postscount);

Here's echo:

{
echo "Posts: ".$posts." ";
}

I tried with this:

{
    echo '<pre>';
    print_r($posts);
    echo '</pre>';
}

with print_r it retuns this:

Array ( [0] => 73 )

and with var_dump()

array(1) { [0]=> string(2) "73" }

Answer 1

Try this code

$postscount = mysql_query('select count(authorid) from topics where authorid="'.$author.'" ') or die(mysql_error());
$posts = mysql_fetch_row($postscount);
var_dump($posts);
echo "There are ".$posts[0]. " authors";

Here

or die(mysql_error()) 

will tell you that query was successful or not.
