Question

i’ve got a query and i try to get some results like this:

    while ($keywords = mysql_fetch_array($keys1)){
    foreach ($keywords as $key) {
        $pos2 = strripos($key, $dquote);
            if ($pos2 === false) { } else { 
                $clean_dquote = str_replace('"', "", $key);
                print_r($clean_dquote);
                echo '<br>';
            } 
    }
}

the raw result from the while loop will be :

"test"
"test1"

i am using str_replace to make it look like this:

test
test1

what happens is that i get back:

test
test
test1
test1

is that because i use a while and a foreach?, but if i take one out i don’t get no results

any ideas?

thanks

As said in http://cn.php.net/manual/en/function.mysql-fetch-array.php

Returns an array of strings that corresponds to the fetched row, or FALSE if there are no more rows.
The type of returned array depends on how result_type is defined. By using MYSQL_BOTH (default), you’ll get an array with both associative and number indices. Using MYSQL_ASSOC, you only get associative indices (as mysql_fetch_assoc() works), using MYSQL_NUM, you only get number indices (as mysql_fetch_row() works).
