ldap_errno
(PHP 4, PHP 5, PHP 7)
ldap_errno — Return the LDAP error number of the last LDAP command
설명
int ldap_errno
( resource
$link_identifier
)Returns the standardized error number returned by the last LDAP command. This number can be converted into a textual error message using ldap_err2str().
반환값
Return the LDAP error number of the last LDAP command for this link.
예제
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 (!$res) {
echo "LDAP-Errno: " . ldap_errno($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";
?>
참고
- ldap_err2str() - Convert LDAP error number into string error message
- ldap_error() - Return the LDAP error message of the last LDAP command

Couple of good error codes to get started. If you want to detect failure of ldap_add due to the record already existing, ldap_error == 0x44. This means, you can do something like:
$r = ldap_add($ds, $dn, $info);
if (!$r) {
if (ldap_errno($ds) == 0x44) {
// Do something about it
} else {
// A real failure
}
}
Similarly, on ldap_delete, you will get a 0x20 value (No Such Object) if you try to delete something that isn't there.
