ldap_errno -- Return the LDAP error number of the last LDAP command

Description

int ldap_errno ( resource link_identifier)

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

This function returns the standardized error number returned by the last LDAP command for the given link_identifier. This number can be converted into a textual error message using ldap_err2str().

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.

Example 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 (!$res) { printf("LDAP-Errno: %s<br>\n", ldap_errno($ld)); printf("LDAP-Error: %s<br>\n", ldap_error($ld)); die("Argh!<br>\n"); } $info = ldap_get_entries($ld, $res); printf("%d matching entries.<br>\n", $info["count"]); ?>
