maxdb_connect_error

(PECL maxdb >= 1.0)

maxdb_connect_error — Returns a string description of the last connect error

说明

maxdb_connect_error ( void ) : string

The maxdb_connect_error() function is identical to the corresponding maxdb_connect_errno() function in every way, except instead of returning an integer error code the maxdb_connect_error() function will return a string representation of the last error to occur for the last maxdb_connect() call. If no error has occurred, this function will return an empty string.

返回值

A string that describes the error. An empty string if no error occurred.

范例

Example #1 maxdb_connect_error sample

 <?php

$link = maxdb_connect("localhost", "nonexisting_user", "");

if (!$link) {
   printf("Can't connect to localhost. Error: %s\n", maxdb_connect_error());
}
?>

以上例程的输出类似于：

PHP Warning:  maxdb_connect(): -4008 POS(1) Unknown user name/password combination <...>
Can't connect to localhost. Error: POS(1) Unknown user name/password combination
