ldap_connect — Connect to an LDAP server
$ldap_uri = NULL
] ) : resourceThe following signature is still supported for backwards compatibility, but is considered deprecated and should not be used anymore!
$host = NULL
[, int $port = 389
]] ) : resource
Creates an LDAP link identifier and checks whether the given
host and port are plausible.
Note: This function does not open a connection. It checks whether the given parameters are plausible and can be used to open a connection as soon as one is needed.
ldap_uriA full LDAP URI of the form ldap://hostname:port or ldaps://hostname:port for SSL encryption.
You can also provide multiple LDAP-URIs separated by a space as one string
Note that hostname:port is not a supported LDAP URI as the schema is missing.
hostThe hostname to connect to.
portThe port to connect to.
Returns a positive LDAP link identifier when the provided LDAP URI
seems plausible. It's a syntactic check of the provided parameter but the server(s) will not
be contacted! If the syntactic check fails it returns FALSE.
ldap_connect() will otherwise
return a resource as it does not actually connect but just
initializes the connecting parameters. The actual connect happens with
the next calls to ldap_* funcs, usually with
ldap_bind().
If no argument is specified then the link identifier of the already opened link will be returned.
Example #1 Example of connecting to LDAP server.
<?php
// LDAP variables
$ldapuri = "ldap://ldap.example.com:389"; // your ldap-uri
// Connecting to LDAP
$ldapconn = ldap_connect($ldapuri)
or die("That LDAP-URI was not parseable");
?>
Example #2 Example of connecting securely to LDAP server.
<?php
// make sure your host is the correct one
// that you issued your secure certificate to
$ldaphost = "ldaps://ldap.example.com/";
// Connecting to LDAP
$ldapconn = ldap_connect($ldaphost)
or die("That LDAP-URI was not parseable");
?>
