Flattening multidimensional array created by json_decode - php

Question

I'm trying to flatten a multidimensional array that was returned by json_decode() but I'm having issues. I've some research but all of the solutions seem to be skipping over some of my data. If I run this and compare the echo'd data to var_dump() I'm definitely not getting everything and I'm not sure why.
Here is what I have so far:
<?php
function array_flatten($array) {
if (!is_array($array)) {
return false;
}
$result = array();
foreach ($array as $key => $value) {
if (is_array($value)) {
$result = array_merge($result, array_flatten($value));
} else {
$result[$key] = $value;
}
}
return $result;
}
for ($x = 1; $x <= 1; $x++) {
$response = file_get_contents('https://seeclickfix.com/api/v2/issues?page='.$x
.'&per_page=1');
// Decode the JSON and convert it into an associative array.
$jsonDecoded = json_decode($response, true);
$flat = array_flatten($jsonDecoded['issues']);
foreach($flat as $item) {
echo $item;
echo "<br>";
}
}
?>

array_merge will overwrite values with the same key, as you can see in the documentation. E.g. in the link you posted, you will lose some urls. You could fix that by create unique keys in the flattened array. For example by passing a prefix to your function:
function array_flatten($array, $prefix = '') {
if (!is_array($array)) {
return false;
}
$result = array();
foreach ($array as $key => $value) {
if (is_array($value)) {
$result = array_merge($result, array_flatten($value, $prefix.'_'.$key));
} else {
$result[$prefix.'_'.$key] = $value;
}
}
return $result;
}
