Change an associative array into an indexed array / get an Zend_Table_Row_Abstract as non-associative

Question

Hi out there in Stackland. I was wondering if there was either a function or an easy way to change an associative array into an indexed array.

To elaborate, I'm using the Zend framework, and I've got a point in my site where I take out a row of an SQL table as an associative array. I've passed it to javascript via an echoed in JSON. However, I've noticed that I can see the names of my database's columns in Firebug. Having outsiders know the names of your tables and columns is a big security no-no, so I'd like to change it from

SQLarray[user_id]
SQLarray[block_id]
SQLarray[b_price] etc.

to

SQLarray[0]
SQLarray[1]
SQLarray[2] etc.

Is there a good way to do this?

It would also work to be able to have a Zend_Table_Abstract->fetchAll() return a non-associative array, but I don't think that's possible. Thanks for your help!

Answer 1

Is pure php ok?

$array = array_values($array);

Answer 2

define function

function array_default_key($array) {
    $arrayTemp = array();
    $i = 0;
    foreach ($array as $key => $val) {
        $arrayTemp[$i] = $val;
        $i++;
    }
    return $arrayTemp;
}

Pass the associative array as a parameter and it will convert into the default index of the array. For example: we have Array('2014-04-30'=>43,'2014-04-29'=>41) after the call to the function the array will be Array(0=>43,1=>41).

You could use this simple piece of code, if you do not want to use the inbuilt PHP function.

$input_array;           // This is your input array
$output_array = [];     // This is where your output will be stored.
foreach ($input_array as $k => $v){
    array_push($output_array, $v);
}
print_r($output_array);
