Description:
------------
incorrect path save export file

Reproduce code:
---------------
<pre>
kpe1.php
<?
set_time_limit(0);
$ssl_configargs = array("digest_alg" => "OPENSSL_ALGO_SHA1",
"private_key_bits" => 384,"encrypt_key" => false,"basicConstraints" => "CA:true","keyUsage" => "cRLSign, keyCertSign",
"nsCertType" => "sslCA, emailCA");
$dn = array("countryName" => 'IT',"stateOrProvinceName" => 'Italy',
"localityName" => 'city',"organizationName" => 'org',
"organizationalUnitName" => 'unit',"commonName" => 'name' ,"emailAddress" => 'mail' );
$numberofdays = '365';
$pkey = openssl_pkey_new( $ssl_configargs );
$csr = openssl_csr_new( $dn, $privkey, $ssl_configargs );
$sscert = openssl_csr_sign( $csr, null, $privkey, $numberofdays );
openssl_csr_export( $csr, $csrout );
openssl_x509_export( $sscert, $certout );
openssl_x509_export_to_file ($sscert ,'crt_509_sk.crt',false);
openssl_pkey_export( $privkey, $pkeyout, $configargs['licence_pwd' ]);
openssl_pkey_export_to_file($privkey,'crt_509_pk.pem');

Expected result:
----------------
[dir]
kpe1.php
crt_509_sk.crt
crt_509_pk.pem

Actual result:
--------------
C:\Programmi\Apache Software Foundation\Apache2.2
.....
crt_509_sk.crt
crt_509_pk.pem
.....
