警告：trim（）期望参数1为字符串，对象在   第94行的C：\ xampp \ htdocs \ motor \ classes \ user.Class.php

警告：trim（）期望参数1为字符串，对象在   第96行的C：\ xampp \ htdocs \ motor \ classes \ user.Class.php

第94行如下：

if($this->bd->real_escape_string(trim($this->cuvant_cautat)) == $cuvintele[0])

第96行如下：

elseif($this->bd->real_escape_string(trim($this->cuvant_cautat)) == $cuvintele[1])

我这样解决了：

public function Extragere_tabel()
{
    if($this->cuvant_cautat)
    {
        $cuvv=$this->cuvant_cautat;
        $this->cuvant_cautat = $this->bd->query("SELECT cuvant_stimul, cuvant_raspuns, aparitii FROM dc_asociatii WHERE cuvant_stimul='".$this->bd->real_escape_string(trim($this->cuvant_cautat))."' OR cuvant_raspuns='".$this->bd->real_escape_string(trim($this->cuvant_cautat))."' ORDER BY aparitii DESC");
        echo "<br /><center><table border=1 width=500>
        <tr><td><strong>Слово – стимул</strong></td><td><strong>Слово – реакция</strong></td><td><strong>Kоличество</strong></td></tr>";
        while($cuvintele = $this->cuvant_cautat->fetch_array(MYSQLI_NUM))
            {
                if($cuvv == $cuvintele[0])
                    echo "<tr><td>$cuvintele[0]</td><td>$cuvintele[1]</td><td>$cuvintele[2]</td></tr>";
                else if($cuvv == $cuvintele[1])
                    echo "<tr><td>$cuvintele[1]</td><td>$cuvintele[0]</td><td>$cuvintele[2]</td></tr>";
            }
        echo "</table></center>";
    }
}

谢谢！
