Is it possible to get email addresses stored in LDAP and send a mail through PHP? The names will be saved in a dropdown box. Once we choose one name from the dropdown the respective email ID should be picked from LDAP and a mail should be sent to it.

Yes, you can access LDAP with PHP (LDAP support in PHP is not enabled by default. You will need to use the --with-ldap[=DIR] configuration option )
Here is the full PHP documentation on the subject: (http://php.net/manual/en/book.ldap.php)
Here is a basic example how you can access LDAP and retrieve information from PHP's documentation.
<?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>";
}
?>

Appreciate your quick response, but this is the error I am getting ldap_search(): Search: Operations error on line 18 ldap_count_entries() expects parameter 2 to be resource, boolean given on line 21 ldap_get_entries() expects parameter 2 to be resource, boolean given on line 24 and this is the output Connecting ...connect result is Resource id #2 Binding ...Bind result is 1 Searching for (sn=S*) ...Search result is Number of entries returned is Getting entries ... Data for items returned: Closing connection I am completely new to this.

Check your binding. The function ldap_bind accepts 2 more parameters bind_rdn and bind_password if there are not provided anonymous bind is executed: php.net/manual/en/function.ldap-bind.php

Thanks! It is working now. I defined the username and password in the ldap bind for it to work :) Appreciate your assistance. :)
