[英]mysqli php extend
i was wondering if you could point me in the right direction. 我想知道你是否能指出我正确的方向。 Im extending the mysqli class but cant seem to call the error function..
我扩展了mysqli类,但似乎无法调用错误函数..
<?php
class mysqli_ls extends mysqli
{
private $activeConnection = 0;
private $linkArr = array();
private $queryArr = array();
private $errorArr = array();
public function __construct()
{
}
/* Connection ************************************************************ */
public function connect($host='', $username='', $password='', $port='', $database='')
{
$no =& $this->activeConnection;
$no++;
if ( empty($host) || empty($username) || empty($password) || empty($port) || empty($database) )
{
$this->setError('1', 'connect','missing required variables');
return false;
}
$this->linkArr[ $no ] = parent::mysqli($host,$username,$password);
if ( $this->linkArr[ $no ] === false )
{
$this->setError(2, 'connect', parent::error( $this->linkArr[ $no ] ) );
return false;
}
return $no;
}
Fatal error: Call to undefined method mysqli::error() in C:\\wamp\\www\\vhdocs\\test\\mysqli.class.php on line 31 致命错误:在第31行的C:\\ wamp \\ www \\ vhdocs \\ test \\ mysqli.class.php中调用未定义的方法mysqli :: error()
i've also tried parent::mysqli_error and had the same error... I cant see why i cant call the error..... 我也尝试过parent :: mysqli_error并遇到相同的错误...我看不到为什么我无法调用该错误.....
Try $this->error
(it's a property, not a function in OO style). 试试
$this->error
(它是一个属性,而不是OO风格的函数)。 See also the examples at the php manual 另请参见php手册中的示例
