Store unique values within foreach loop - php

Question

Im trying to get value of ids for different values of a foreach loop but im confused how to go about it.
$revenue = array('pseudo1', 'pseudo2');
foreach ($revenue as $value) {
if (!$revenue_type) {
$st = getValueDescription($value);
foreach ($st as $stype) {
$tpe[] = $stype->id;
}
$rev[$value] = $tpe;
}
}
when i dump $rev this is what i get
array (size=1)
0 =>
array (size=3)
'pseudo1' =>
array (size=2)
0 => string '9' (length=1)
1 => string '19' (length=2)
'pseudo2' =>
array (size=4)
0 => string '9' (length=1)
1 => string '19' (length=2)
2 => string '1' (length=1)
3 => string '35' (length=2)
what i actually expect
array (size=1)
0 =>
array (size=3)
'pseudo1' =>
array (size=2)
0 => string '9' (length=1)
1 => string '19' (length=2)
'pseudo2' =>
array (size=4)
2 => string '1' (length=1)
3 => string '35' (length=2)
I need the result of my $rev to contain $value as keys but previous values of $tpe keeps adding up with each iteration, im confused how to achieve this.

Answer 1

Does this solve your problem?
$revenue = array('pseudo1', 'pseudo2');
$uniqueValues = [];
foreach ($revenue as $value) {
if (!$revenue_type) {
$st = getValueDescription($value);
$tpe = [];
foreach ($st as $stype) {
if (!in_array($stype->id, $uniqueValues)) {
$tpe[] = $stype->id;
$uniqueValues[] = $stype->id;
}
}
$rev[$value] = $tpe;
}
}
$uniqueValues holds the IDS you already added to the $rev variable, and the $tpe gets empty after every iteration
