Description

array ldap_get_values ( resource link_identifier, resource result_entry_identifier, string attribute)

Returns an array of values for the attribute on success and FALSE on error.

ldap_get_values() function is used to read all the values of the attribute in the entry in the result. entry is specified by the result_entry_identifier. The number of values can be found by indexing "count" in the resultant array. Individual values are accessed by integer index in the array. The first index is 0.

This call needs a result_entry_identifier, so needs to be preceded by one of the ldap search calls and one of the calls to get an individual entry.

You application will either be hard coded to look for certain attributes (such as "surname" or "mail") or you will have to use the ldap_get_attributes() call to work out what attributes exist for a given entry.

LDAP allows more than one entry for an attribute, so it can, for example, store a number of email addresses for one person's directory entry all labeled with the attribute "mail"

return_value["count"] = number of values for attribute
return_value[0] = first value of attribute
return_value[i] = ith value of attribute

例子 1. List all values of the "mail" attribute for a directory entry


<?php
// $ds is a valid link identifier for a directory server

// $sr is a valid search result from a prior call to
//     one of the ldap directory search calls

// $entry is a valid entry identifier from a prior call to
//        one of the calls that returns a directory entry

$values = ldap_get_values($ds, $entry, "mail");

echo $values["count"] . " email addresses for this entry.<br />";

for ($i=0; $i < $values["count"]; $i++) {
    echo $values[$i] . "<br />";
}
?>
