imap function is not working for me with PHP

I try to access my gmail account with PHP, but I get an error message in line 2. IMAP is enabled in Gmail, while POP is not enabled.

$mbox = imap_open("{imap.gmail.com:993/ssl}", "email@gmail.com", "password");

echo "<h1>Mailboxes</h1>\n";
$folders = imap_listmailbox($mbox, "{imap.gmail.com:993}", "*");

if ($folders == false) {
    echo "Call failed<br />\n";
}
else {
    foreach ($folders as $val) {
        echo $val . "<br />\n";
    }
}

echo "<h1>Headers in INBOX</h1>\n";
$headers = imap_headers($mbox);

if ($headers == false) {
    echo "Call failed<br />\n";
}
else {

You need to enable imap in your php.ini.

I used the wamp menu to edit the php.ini. I enabled the php_imap.dll.

I got the solution:

I am running Windows 7 64bit environment with WAMP server, it has two php.ini files:

1] C:\wamp\bin\apache\apache2.2.22\bin
   Enable php_imap.dll extension by removing ; at beginning of string

2] C:\wamp\bin\php\php5.3.13
   Enable php_imap.dll extension by removing ; at beginning of string

And it works now !
