From the PHP docs: http://php.net/manual/en/language.types.type-juggling.php 来自PHP文档: http : //php.net/manual/en/language.types.type-juggling.php
Build a temporary array and implode it: 构建一个临时数组并将其内爆:
foreach($related AS $r) {
$temp[$r->id_product][] = $r->related;
$rels[$r->id_product] = implode(', ', $temp[$r->id_product]);
}
print_r($rels);
