ldap_errnoReturn the LDAP error number of the last LDAP command

说明

ldap_errno(LDAP\Connection $ldap): int

Returns the standardized error number returned by the last LDAP command. This number can be converted into a textual error message using ldap_err2str().

参数

ldap

An LDAP\Connection instance, returned by ldap_connect().

返回值

Return the LDAP error number of the last LDAP command for this link.

更新日志

版本 说明
8.1.0 The ldap parameter expects an LDAP\Connection instance now; previously, a 资源(resource) was expected.

范例

Unless you lower your warning level in your php.ini sufficiently or prefix your LDAP commands with @ (at) characters to suppress warning output, the errors generated will also show up in your HTML output.

示例 #1 Generating and catching an error

<?php
// This example contains an error, which we will catch.
$ld ldap_connect("localhost");
$bind ldap_bind($ld);
// syntax error in filter expression (errno 87),
// must be "objectclass=*" to work.
$res =  @ldap_search($ld"o=Myorg, c=DE""objectclass");
if (!
$res) {
    echo 
"LDAP-Errno: " ldap_errno($ld) . "<br />\n";
    echo 
"LDAP-Error: " ldap_error($ld) . "<br />\n";
    die(
"Argh!<br />\n");
}
$info ldap_get_entries($ld$res);
echo 
$info["count"] . " matching entries.<br />\n";
