Please note that "file://path/to/file.pem" in documentation means file protocol + file path. In UNIX like OS, that is something like file:///rsa_private_key.pem. There is THREE slashes in the path string, not TWO.

At least as of PHP 5.2.5, this function's prototype matches what is given on this page (i.e. it does not require an array for its two parameters).

Note that the important part of meint's post is that there is a SINGLE argument: an ARRAY of two elements. In other words, the correct prototype of the function is

resource openssl_pkey_get_private ( array params )

where params = array( 0 => $key, 1 => $passphrase)

Thanks, meint, you made my day!

Trying for hours to get openssl_pkey_get_private to load my private key (no problems with openssl_pkey_get_public) I found that the following loaded the private key correctly:

$passphrase="test";
$priv_key_file_name = ("./private.pem");

if (openssl_pkey_get_private(array("file://$priv_key_file_name", $passphrase)))
{
        print "\nPrivate Key OK\n\n";
} else {
        print "\nPrivate key NOT OK\n\n";
}
