Hey! Wow!
yes it's very blaming. Your code looks mutch more better!
The $e was just for convenience.
Actually I need something like this as end result:
for($i=1;$i<count($pidsArray);$i++):
$qString = "SELECT cl_to,count(*) as cl_count from
".$wgDBprefix."categorylinks where
cl_from='".$pidsArray[$i]."' group by
cl_to having cl_count >0";
$wgRes = $db->query($qString);
while($row = $db->fetchObject($wgRes)):
$categories[$i]['cl_to']=$row->cl_to;
$categories[$i]['cl_count']=$row->cl_count;
endwhile;
endfor;
Is there a way to modify your code in this direction?

This will only get a series of cl_to's. I'm not sure what that $e is for,
or what the /dev/null style fetchObject call is for, and I'm not sure what
data output you're expecting. So I'll need more information if you want
other information in the rows, a count, or a grouping of things together.
$res = $db->select(
array('categorylinks', 'imagelinks', 'page'),
array( 'cl_to' ),
array(
'page_id' => $pidsArray,
'page_namespace' => NS_FILE,
),
__METHOD__,
array(),
array(
'imagelinks' => array( 'JOIN', 'il_from=cl_from' ),
'page' => array( 'JOIN', 'page_title=il_to' ),
)
);
foreach ( $res as $row ) {
$row->cl_to;
// [...]
}
(Side-note; Uuuuughhh... A $wg that's not global, raw sql queries, unescaped
SQL concatenation (including what looks like an SQL injection vector),
hardcoded NS number, for() where foreach() is usable, $arr[$i] instead of
$arr[]... that code is........................ <facepalm/>)

Hi all!
Could someone translate this to a single sophisticated mysql-statement
(perhaps with a count() on the categories-result)?
The code below retrieves category links from pages (articles)
containing specific files.
At the beginning I only have page ids from the filepages.
for($i=1;$i<count($pidsArray);$i++):
$qString = "SELECT page_title FROM ".$wgDBprefix."page
where page_id='".$pidsArray[$i]."' and page_namespace=6";/* File:
namespace */
$wgRes = $db->query($qString);
while($row = $db->fetchObject($wgRes)):
$imagePages[$i]=$row->page_title;
endwhile;
endfor;
$e=0;
for($i=1;$i< count($imagePages);$i++):
$qString = "SELECT il_from FROM ".$wgDBprefix."imagelinks
where
il_to='".$imagePages[$i]."'";/* File: namespace */
$wgRes = $db->query($qString);
$row = $db->fetchObject($wgRes);
while($row = $db->fetchObject($wgRes)):
$imageLinks[$e]=$row->il_from;
endwhile;
endfor;
for($i=0;$i<count($imageLinks);$i++):
$qString = "SELECT cl_to FROM
".$wgDBprefix."categorylinks where
cl_from='".$imageLinks[$i]."'";
$wgRes = $db->query($qString);
while($row = $db->fetchObject($wgRes)):
$categories[$i]=$row->cl_to;
endwhile;
endfor;
