array_merge help please - confused

[jokerfool]

I am getting this error and I don't know what it means, the script has no support behind it so I have come here, can someone tell me what this means please:

 

[02-Jan-2009 11:45:31] PHP Warning:  array_merge() [<a href='function.array-merge'>function.array-merge</a>]: Argument #2 is not an array in /home//includes/load_category.php on line 26

 

The line 26 refers to this line:

 

$en = array_merge($en,$line);

 

The line 26 is made up of this section:

 

//Find Category
        $parent = 0;
        $url = '';
        $path = '<a class=title_links href="'.constant('dir').'">'._home.'</a>';

        while (count($cats) > 0) {
                $cat = array_shift($cats);
                $result = mysql_query("SELECT * FROM $catstable WHERE c_parent=$parent AND c_url='".$cat."'") or die(mysql_error());
                $line = mysql_fetch_assoc($result);
                $en = array_merge($en,$line);
                if (mysql_num_rows($result) == 0) call404();
                $parent = $line[c_id];
                $url .= '/'.$line[c_url];
                if (substr($url,0,1) == '/') $url = substr($url,1);
                $path .= ' : <a class=title_links href="'.constant('dir').$url.'">'.$line[c_name].'</a>';
                }

 

Thank you.

It looks like that database query is returning an empty result

[flyhoney]

Switching these two lines might solve the problem:

 

change:

$en = array_merge($en,$line);
if (mysql_num_rows($result) == 0) call404();

 

to:

if (mysql_num_rows($result) == 0) call404();
$en = array_merge($en,$line);

Okay will leave this for about an hour then reply and see what errors I am generating, thank you.

Whilst I wait for the errors to appear there I am getting another error elsewhere, same array message:

 

PHP Warning:  array_merge() [<a href='function.array-merge'>function.array-merge</a>]: Argument #2 is not an array in /home/admin/includes/manage_members.php on line 257

 

The line refers too:

 

$ll = mysql_fetch_assoc($res); $line = array_merge($line,$ll);

 

That section refers too this:

 

//$line = mysql_fetch_array($result,MYSQL_ASSOC);
//foreach ($line as $key=>$value) echo $key.'='.$value.'<br>';


while ($line = mysql_fetch_array($result,MYSQL_ASSOC))
   if (++$npk >=$from && $npk<=$to) {

        $res = mysql_query("SELECT COUNT(l_id) AS listings FROM $linktable WHERE l_member=$line[$rid]") or die(mysql_error());
        $ll = mysql_fetch_assoc($res); 

	if (is_Array($ll)) {
		$line = array_merge($line,$ll);
	}

        $res = mysql_query("SELECT COUNT(r_id) AS reviews FROM $reviewtable WHERE r_member=$line[$rid]") or die(mysql_error());
        $ll = mysql_fetch_assoc($res); $line = array_merge($line,$ll);

        $res = mysql_query("SELECT COUNT(log_user) AS logins FROM $logstable WHERE log_user=$line[$rid]") or die(mysql_error());
        $ll = mysql_fetch_assoc($res); $line = array_merge($line,$ll);
        $res = mysql_query("SELECT log_time AS lastlog, log_ip AS lastip FROM $logstable WHERE log_user=$line[$rid] ORDER BY log_time DESC LIMIT 1") or die(mysql_error());
        $ll = mysql_fetch_assoc($res); $line = array_merge($line,$ll);

 

Thank you.

Any suggestions please?

try

if($ll = mysql_fetch_assoc($res)) $line = array_merge($line,$ll);
