ldap_get_attributes

Get attributes from a search result entry (PHP 4, PHP 5)
array ldap_get_attributes ( resource link_identifier, resource result_entry_identifier )

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

Parameters

link_identifier: An LDAP link identifier, returned by ldap_connect().
result_entry_identifier

Return Values

Returns a complete entry information in a multi-dimensional array on success and FALSE on error.

Examples

Example 1118. 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++) {

    echo $attrs[$i] . "<br />";

}
?>

Code Examples / Notes » ldap_get_attributes

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($attrs) . " attributes held for this entry: "; for ($i=0; $i<count($attrs); $i++) { echo $attrs[$i] . "<br />"; } ?> You may want to check the time difference with the function "microtime".

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; }

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"; } } }
