PHP: Help troubleshooting when echo's won't execute?

Question

I asked this question here originally:

http://www.daniweb.com/web-development/php/threads/439484/why-arent-more-echos-being-executed

uploaded to the server(form):

sort_mysql results sorts arrays of other queries and returns a 2d arrays of data that was found in all of the data arrays.

EDIT: I solved the problem with echos, now I have a problem with this function (I think):

function sort_mysql_results()
{
    echo "<p>begin smr</p>";
    $match=array();
    $c_match=0;
    $num_it = 0;
    $num_args = func_num_args();
    $c = 0;
    $args = func_get_args();
    while(isset($args[0][$num_it]))
    {
        echo "<p>sort mysql beginning of loop</p>";
        $skip=false;
        $name = $args[0][$num_it]['item_name'];
        $i=1;
        while(isset($args[$i])&&!$skip)
        {
            $skip = !check($args[$i],$name);
            $i++;
        }
        $num_it++;
        if(!$skip)
        {
            $match[$c_match] = $args[0];
            $c_match++;
        }
    }
    echo "<p>Num args: ".$num_args.", Iterations: ".$num_it."</p>";
    return $match;
}

The function gets called like this:

$match = sort_mysql_results(sort_soundex_results($queries[0]),get_array($queries[1]));

Now $match is supposed to be an array. For some reason its not. I try to print results into a table like so:

if(count($match)>0)
{
    $num=0;
    echo "<table>\n
    <tr>\n
    <td>Name</td><td>Category</td><td>Description</td>\n
    </tr>\n";
    while(isset($match[$num]))
    {
        echo "<tr>\n
        <a href=\"product2.php?id=".$match[$num]['ItemID']."\"><td>".$match[$num]['item_name']."</td><td>".$match[$num]['cat_name']."</td><td>".$match[$num]['descr']."</td></a>\n
        </tr>\n";
        $num++;
    }
    echo "</table>\n";
}
else
{
    echo "<p>No matches found. Go back and try different search criteria</p>\n";
}

for reference the mysql table being queried looks like:

 +-------------+--------------+------+-----+---------------------+----------------+
 | Field       | Type         | Null | Key | Default             | Extra          |
 +-------------+--------------+------+-----+---------------------+----------------+
 | item_name   | varchar(100) | NO   |     |                     |                | 
 | ItemID      | mediumint(9) | NO   | PRI | NULL                | auto_increment | 
 | cat_name    | varchar(45)  | NO   |     |                     |                | 
 | userID      | mediumint(9) | NO   |     |                     |                | 
 | descr       | text         | NO   |     |                     |                | 
 | image       | tinytext     | YES  |     | NULL                |                | 
 | date        | timestamp    | NO   |     | CURRENT_TIMESTAMP   |                | 
 | highest_bid | decimal(6,2) | NO   |     | 0.00                |                | 
 | time_expire | timestamp    | NO   |     | 0000-00-00 00:00:00 |                | 
 +-------------+--------------+------+-----+---------------------+----------------+

EDIT: Hope you,re still with me. I did some further debugging:

...
if(count($match)>0)
{
    echo "<p>space</p><h2>In IF STATEMENT VALUE OF MATCH BEFORE WHILE LOOP</h2><p>space</p>\n";
    echo "<p>space</p><p>space</p><p>space</p>\n";
    var_dump($match);
    echo "<p>space</p><p>space</p><p>space</p>\n";
    echo "<h2>VALUE OF match[num]</h2>\n";
    echo "<p>space</p><p>space</p><p>space</p>\n";
    var_dump($match[0]);
    echo "<p>space</p><p>space</p><p>space</p>\n";
...

check this out:

Looks like its supposed to. Whats going on here???

Here is the modified sort_mysql_results:

function sort_mysql_results()
{
    echo "<p>begin smr</p>";
    $match=array();
    $c_match=0;
    $num_it = 0;
    $c = 0;
    $args = func_get_args();
    while(isset($args[0][$num_it]))
    {
        echo "<p>sort mysql beginning of loop</p>";
        $skip=false;
        $name = $args[0][$num_it]['item_name'];
        $i=1;
        while(isset($args[$i])&&!$skip)
        {
            $skip = !check($args[$i],$name);
            $i++;
        }
        if(!$skip) //if found in another parameter
        {
            $match[$c_match] = $args[0][$num_it];
            $c_match++;
        }
        $num_it++;
    }
    echo "<p>Num args: ".$num_args.", Iterations: ".$num_it."</p>";
    var_dump($match);
    return $match;
}

Basically the original only saved the one after the found query and stored the 2D array, not the single array making $match a 3D array. Thanks Madara Uchiha for posting
