Reproduce code:
---------------
<?php
$data = array (
'level0' => array(
'level1'
)
);
// If you uncomment the following a blank screen is outputted.
$flattened = Set::flatten($data);
var_dump($flattened);
class Set {
function flatten($data, $separator = '.') {
$result = array();
$path = null;
if (is_array($separator)) {
extract($separator, EXTR_OVERWRITE);
}
if (!is_null($path)) {
$path .= $separator;
}
foreach ($data as $key => $val) {
if (is_array($val)) {
$result += (array)Set::flatten($val, array(
'separator' => $separator,
'path' => $path . $key
));
} else {
$result[$path . $key] = $val;
}
}
return $result;
}
}
Expected result:
----------------
array(1) {
["level0.0"]=>
string(6) "level1"
}
Actual result:
--------------
Bus error: 10 (core dumped)
