I have this array:
$array[] = [
'a' => $a,
'b' => $b,
];
The array contains of let's say 10 entries, $a can be in there with the same value many times and I need only one of those entries for a db insert.
I can't manage to get array_unique working as it throws
array to string conversion
error when trying to use it like
$result = array_unique($array);
I now made a little foreach loop that feels just wrong to do so:
$z = [];
foreach ($array as $x) {
if (@!in_array($x['a'],$z)) {
$z[] = $x['a'];
}
}
and I use $z for the insert thereafter.
Can someone point me in the right direction of how to distinct my array values?
