I have an associative array with indexed sub-arrays each containing associative arrays which contain content and an index. So like this (in PHP):
$assoc_arr =
array("second" => array(
array("position" => 4,
"content" => "Valiant"),
array("position" => 5,
"content" => "Hail")
),
"first" => array(
array("position" => 0,
"content" => "Hail"),
array("position" => 3,
"content" => "Victors"),
array("position" => 2,
"content" => "the"),
array("position" => 1,
"content" => "to")
)
);
I want to put all of those into an indexed array where their index is their "position" in the associative array. So final array should be:
Array ( [0] => Hail [1] => to [2] => the [3] => Victors [4] => Valiant [5] => Hail )
Currently, I'm merging all of the arrays inside the highest level array, then sorting it by each of those sub-array's positions, then creating an indexed array by pushing the content in order onto a new array. As so:
$pos_arr = array_merge($assoc_arr["second"], $assoc_arr["first"]);
usort($pos_arr, function($a, $b) {
return $a["position"] >= $b["position"] ? 1 : -1;
});
$indexed_arr = array();
foreach ($pos_arr as $elem) {
array_push($indexed_arr, $elem["content"]);
}
It seems like there must be a better way to do this! Can anyone think of one?
The data is coming from a poorly structured XML document which I can't change.
