Change an associative array into an indexed array / get an Zend_Table_Row_Abstract as non-associative
提问by Ethan
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.
你好在斯塔克兰。我想知道是否有函数或简单的方法可以将关联数组更改为索引数组。
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
详细地说，我正在使用 Zend 框架，并且我在我的站点中有一个点，我将 SQL 表的一行作为关联数组取出。我已经通过 JSON 中的回显将它传递给 javascript。但是，我注意到我可以在 Firebug 中看到我的数据库列的名称。让外人知道你的表和列的名称是一个很大的安全禁忌，所以我想把它从
SQLarray[user_id]
SQLarray[block_id]
SQLarray[b_price] etc.
to
到
SQLarray[0]
SQLarray[1]
SQLarray[2] etc.
Is there a good way to do this?
有没有好的方法可以做到这一点？
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!
也可以让 Zend_Table_Abstract->fetchAll() 返回一个非关联数组，但我认为这是不可能的。谢谢你的帮助！

define function
定义函数
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).
将关联数组作为参数传递，它将转换为数组的默认索引。例如：Array('2014-04-30'=>43,'2014-04-29'=>41)在调用函数之后，数组将是Array(0=>43,1=>41)。

for multi layered array i use this:
对于多层阵列，我使用这个：
function getIndexedArray($array) {
$arrayTemp = array();
for ($i=0; $i < count($array); $i++) {
$keys = array_keys($array[$i]);
$innerArrayTemp = array();
for ($j=0; $j < count($keys); $j++) {
$innerArrayTemp[$j] = $array[$i][$keys[$j]];
}
array_push($arrayTemp, $innerArrayTemp);
}
return $arrayTemp;
}
it turns this:
它变成了这样：
(
[0] => Array
(
[OEM] => SG
[MODEL] => Watch Active2
[TASK_ID] => 8
[DEPT_ASSIGNED] => Purchashing
)
)
into this :
进入这个：
[0] => Array
(
[0] => SG
[1] => Watch Active2
[2] => 8
[3] => Purchashing
)

You could use this simple piece of code, if you do not want to use the inbuilt PHP function.
如果您不想使用内置的 PHP 函数，您可以使用这段简单的代码。
$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);
