Example #1 LDAP search example

`<?php
// basic sequence with LDAP is connect, bind, search, interpret search
// result, close connection
echo "<h3>LDAP query test</h3>";
echo "Connecting ...";
$ds=ldap_connect("localhost"); // must be a valid LDAP server!
echo "connect result is " . $ds . "<br />";
if ($ds) {
echo "Binding ...";
$r=ldap_bind($ds); // this is an "anonymous" bind, typically
// read-only access
echo "Bind result is " . $r . "<br />";
echo "Searching for (sn=S*) ...";
// Search surname entry
$sr=ldap_search($ds, "o=My Company, c=US", "sn=S*");
echo "Search result is " . $sr . "<br />";
echo "Number of entries returned is " . ldap_count_entries($ds, $sr) . "<br />";
echo "Getting entries ...<p>";
$info = ldap_get_entries($ds, $sr);
echo "Data for " . $info["count"] . " items returned:<p>";
for ($i=0; $i<$info["count"]; $i++) {
echo "dn is: " . $info[$i]["dn"] . "<br />";
echo "first cn entry is: " . $info[$i]["cn"][0] . "<br />";
echo "first email entry is: " . $info[$i]["mail"][0] . "<br /><hr />";
}
echo "Closing connection";
ldap_close($ds);
} else {
echo "<h4>Unable to connect to LDAP server</h4>";
}
