PHP ldap_bind“例外”

Question

This is my code and it is working corrently.

$authenticated = ldap_bind($conn, $this->username . "@" . $servidor_dominio, $this->password);

The description of this function specifies that it returns bool. When the user types an incorrect combination of username and password I get an error from the server:

Error 500. ldap_bind(): Unable to bind to server: Invalid credentials

This is truly a PHP Warning but it stops the execution of my app. It even shows the stack trace page (I'm working with Yii PHP Framework).

I tried capturing an exception putting the ldap_bind() call inside a try/catch block:

try {
    $authenticated = ldap_bind($conn, $this->username . "@" . $servidor_dominio, $this->password);
} catch (Exception $exc) {
    echo $exc->getTraceAsString();
}

It doesn't catch any exception and I'm still getting the same error:

Error 500 ldap_bind(): Unable to bind to server: Invalid credentials

Can someone help me with this? It seems that my users miss types their login credentials too often ;-)

只需在ldap_bind前面放置一个@符号，然后使用$ authenticated变量（如果他们正确地进行了验证）就可以向用户显示。

$authenticated = @ldap_bind($conn, $this->username . "@" . $servidor_dominio, $this->password);
