Question

我正在尝试构建某种类型的数据库类（所有PDO）。到目前为止，我的所有函数都在运行，但insert语句运行了两次。我真的不知道哪里出错了。当我运行带有回声的代码时，回声只出现一次所以我不认为它实际上被执行了两次......

当我将getBind函数与其他语句一起使用时，它的工作完全正常......

代码

 function insert ($p_sTable, $p_aCol, $p_aVal) {

    $this->m_sQuery .= "INSERT INTO ".$p_sTable." (";

    $queryCols = "";
    foreach ($p_aCol as $col) { ... }

    $this->m_sQuery .= $queryCols.") VALUES (";

    $queryPlaceholders = "";
    foreach ($p_aCol as $placeholder) {... }

    foreach ($p_aVal as $p_aValtosave) { .... }


    $this->m_sQuery .= $queryPlaceholders.")";

    echo "m_sQuery:</br>".$this->m_sQuery;

    echo "</br>print bindCol</br>";
    print_r($this->m_aBindCol);

    echo "</br>print bindVal</br>";
    print_r($this->m_aBindVal);


    return $this;

}

我在哪里召唤功能：

$db = Db::getConnection();
$arr = $db->insert("geprutsvanlisa",["kolom1","kolom2"], ["24", "24"])->getBind();

输出：m_sQuery：

INSERT INTO geprutsvanlisa (kolom1, kolom2) VALUES (:ikolom1, :ikolom2)
print bindCol
Array ( [0] => ikolom1 [1] => ikolom2 ) 
print bindVal
Array ( [0] => 24 [1] => 24 ) 
echo i:0
bindvalue(:ikolom1, 24) 
echo i:1
bindvalue(:ikolom2, 24)

回显此ms查询

INSERT INTO geprutsvanlisa (kolom1, kolom2) VALUES   (:ikolom1, :ikolom2)
echo this bindcol Array ( [0] => ikolom1 [1] => ikolom2 ) 
echo this bindval Array ( [0] => 24 [1] => 24 )

Insert语句运行两次
