Fwd: [PHP] Re: usort(): The argument should be an array

[Remember14a]

If I put this code   $res = array(); while($row = mysql_fetch_assoc($query_result)) {   before   usort($res, "cmp"); give this error     Parse error: parse error, unexpected $ in /home2/wwwabcde/public_html/search/searchfuncs.php on line 316   even  putting this code before     $res[$i]['size'] = $row[5];     $res[$i]['weight'] = $result_array[$row[0]];     $i++; } usort($res, "cmp"); gives same error.

I have done as per your instructions, and put

var_dump($res);

BEFORE

usort($res, "cmp");

Please, go again to

Enter law we get this output. NULL *Warning*: usort(): The argument should be an array in */home2/wwwabcde/public_html/search/searchfuncs.php* on line *301*

So you're not setting $res at all.

You should be doing:

# INITIALIZE RESULTS ARRAY HERE.
$res = array();

while($row = mysql_fetch_assoc($query_result)) {

..........................

   $res[$i]['size'] = $row[5];

   $res[$i]['weight'] = $result_array[$row[0]];

   $i++;
}

usort($res, "cmp");

that will fix your problem (I know someone suggested this before too).
