Returns multiple values from a PHP function - php

Question

Apologize for the repeated question. Return multiple values from database with function. I tried executing code, the function returns one value, where I want all the values of id and name.
Database: id and name has 9 rows. Is there anything I was missing in my code.
function readdata() {
$sth = $db->execute('SELECT * FROM mynumbers m WHERE m.id>1 ORDER BY m.id ASC');
foreach ($sth as $s) {
$object = new stdClass();
$object->id = $s->id;
$object->name = $s->name;
return $object;
}
}
$rd = readdata();
echo $rd->id;
echo $rd->name;

Answer 1

May be something like this:
function readdata() {
$sth = $db->execute('SELECT * FROM mynumbers m WHERE m.id>1 ORDER BY m.id ASC');
$out = [];
foreach ($sth as $s) {
$object = new stdClass();
$object->id = $s->id;
$object->name = $s->name;
$out[] = $object;
}
return $out;
}
$rd = readdata();
//and here
foreach($rd as $obj){
echo $obj->id;
echo $obj->name;
}

This is more a suggestion than an answer. Why re-inventing the wheel? PDO already is capable of returning classes and also fetching all results into an array.
function readdata(PDO $db): array
{
$sth = $db->prepare('SELECT * FROM mynumbers m WHERE m.id>1 ORDER BY m.id ASC');
$sth->execute();
return $sth->fetchAll(PDO::FETCH_CLASS);
}
$objects = readdata($db);
$objects is now an array. Each element contains a stdClass object with each column name as property.
foreach($objects as $object) {
echo $object->id, PHP_EOL;
echo $object->name, PHP_EOL;
}

Your foreach loop intends to run through all values of the array $sth, but returns only with the FIRST one.
You can just return $sth to get the whole array, or build a new array and append to it:
$ret = array();
foreach ($sth as $s) {
...
$ret[] = $object;
}
and then
return $ret;
