# ldap_get_values

(PHP 4, PHP 5, PHP 7)

ldap_get_values — Get all values from a result entry

### 说明

ldap_get_values ( resource `$link_identifier` , resource `$result_entry_identifier` , string `$attribute` ) : array

Reads all the values of the attribute in the entry in the result.

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.

### 参数

`link_identifier`

  An LDAP link identifier, returned by ldap_connect().

`result_entry_identifier`

`attribute`

### 返回值

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

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

### 范例

Example #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 />";
    }
    ?>
