It's good practice to use array_change_key_case() on the result of ldap_get_attributes() so your program can ignore case in attribute names just like ldap itself does. (You wouldn't want ldap_get_attributes to _always_ flatten the case because you need a way to get the attribute names in a pretty format for display to the user.)

ldap_get_attributes
(PHP 4, PHP 5, PHP 7, PHP 8)
ldap_get_attributes — Get attributes from a search result entry
说明
Reads attributes and values from an entry in the search result.
Having located a specific entry in the directory, you can find out what information is held for that entry by using this call. You would use this call for an application which "browses" directory entries and/or where you do not know the structure of the directory entries. In many applications you will be searching for a specific attribute such as an email address or a surname, and won't care what other data is held.
return_value["count"] = number of attributes in the entry return_value[0] = first attribute return_value[n] = nth attribute return_value["attribute"]["count"] = number of values for attribute return_value["attribute"][0] = first value of the attribute return_value["attribute"][i] = (i+1)th value of the attribute
返回值
Returns a complete entry information in a multi-dimensional array
on success and false on error.

现在 ldap 参数接受 LDAP\Connection
实例，之前接受 资源(resource)。

The entry parameter expects an LDAP\ResultEntry
instance now; previously, a 资源(resource) was expected.

示例 #1 Show the list of attributes held for a particular directory entry
<?php
// $ds is the link identifier for the directory
// $sr is a valid search result from a prior call to
// one of the ldap directory search calls
$entry = ldap_first_entry($ds, $sr);
$attrs = ldap_get_attributes($ds, $entry);
echo $attrs["count"] . " attributes held for this entry:<p>";
for ($i=0; $i < $attrs["count"]; $i++) {

The array created by this function is similar to the on from ldap_get_entries() but when it creates array keys it alters the attribute's case inconsistently.
ldap_get_entries() lowercases all of the attributes before keying the array with them, but this function appears to leave things as they are.
If you're having problems, do a print_r and make sure you're using correct case for array keys. For example, you might need to use "objectClass" and not "objectclass".

As of PHP 4.0.5, the ldap_get_attributes function does not work with binary data. If you're fetching a JPEG from an LDAP server, use ldap_get_values_len instead.

Note that ldap_get_attributes fetches attributes AND values from the LDAP server. Depending on the data stored in the entry, the following code might work a dozen times faster (or even better, but faster in general) than the code in Example 1:
<?php
// $ds is the link identifier for the directory
// $sr is a valid search result from a prior call to
// one of the ldap directory search calls
$entry = ldap_first_entry($ds, $sr);
$attrs = array();
$attribute = ldap_first_attribute($ds,$entry,$identifier);
while ($attribute) {
$attrs[] = $attribute;
$attribute=ldap_next_attribute($ds,$entry,$identifier);
}
echo count($attrs) . " attributes held for this entry:<p>";
for ($i=0; $i<count($attrs); $i++) {
echo $attrs[$i] . "<br />";
}
?>
You may want to check the time difference with the function "microtime".

Code and function to extract all attributes from all entryes in a certain DN. Maybe not the most timewise efficient but it works.
$entry = ldap_first_entry($ds, $sr);
write_attr($entry,$ds);
for ($i = 0; $i < $n_entries; $i++){
$entry = ldap_next_entry($ds, $entry);
write_attr($entry,$ds);
}
function write_attr($entry,$ds){
$attrs = ldap_get_attributes ($ds, $entry);
for ($j = 0; $j < $attrs["count"]; $j++){
$attr_name = $attrs[$j];
$attrs["$attr_name"]["count"] . "\n";
for ($k = 0; $k < $attrs["$attr_name"]["count"]; $k++) {
echo ">>>>>>";
echo $attr_name.": ".$attrs["$attr_name"][$k]."\n";
}
}
}

I spent quite a while scratching my head about how to read operational attributes such as create and modify timestamps.
This function solved it....
function get_entry_system_attrs( $ds, $dn, $deref=LDAP_DEREF_NEVER )
{
$conn = $ds;
$attrs = array( 'creatorsname', 'createtimestamp', 'modifiersname',
'structuralObjectClass', 'entryUUID', 'modifytimestamp',
'subschemaSubentry', 'hasSubordinates', '+' );
$search = @ldap_read( $conn, $dn, '(objectClass=*)', $attrs, 0, 0, 0, $deref );
if( ! $search )
return false;
$entry = ldap_first_entry( $conn, $search );
if( ! $entry)
return false;
$attrs = ldap_get_attributes( $conn, $entry );
if( ! $attrs )
return false;
if( ! isset( $attrs['count'] ) )
return false;
$count = $attrs['count'];
unset( $attrs['count'] );
$return_attrs = array();
for( $i=0; $i<$count; $i++ ) {
$attr_name = $attrs[$i];
unset( $attrs[$attr_name]['count'] );
$return_attrs[$attr_name] = $attrs[$attr_name];
}
return $return_attrs;
}
