foreach 或 while 只显示最后的结果

Question

这个结构将有几个页面，只有 foreach 或 while 只显示最后一个结果，这个问题发生在我做了这个函数之后，我已经看到了几个问题，并且与 matriz 相关class Layout {   private $sql, $row;   private function set_layout($cond, $cond_r) {     $this->sql = $this->select("*", "table", "".$cond."", array($cond_r));     foreach ($this->sql as $this->row) :       return $this->row['name'];     endforeach;   }   public function get_layout($cond, $cond_r) {      return $this->set_layout($cond, $cond_r);   }}echo $midia->get_layout("WHERE status != ? ORDER BY id DESC", 0);

Answer 1

我不确定，但我认为您正在寻找类似的东西：

class Layout {

private $sql, $row;

    private function set_layout($cond, $cond_r) {

        $this->sql = $this->select("*", "table", "".$cond."", array($cond_r));

        $rows = array();

        foreach ($this->sql as $this->row) :

            $rows[] = $this->row['name'];

        endforeach;

        return implode($rows); //Return array of rows AFTER loop

    }

    public function get_layout($cond, $cond_r) {

        return $this->set_layout($cond, $cond_r);

    }

}

echo $midia->get_layout("WHERE status != ? ORDER BY id DESC", 0);
