Problem with encrypting form data with GnuPG

[phpisnotfordumm]

Hello!

I'm trying to get my PHP form processor to encrypt the data using GnuPG.

Code:

$gpg = 'usr/bin/gpg';
$recipient = '[e-mail]';
$encrypted_message = base64_encode(shell_exec("echo $message | $gpg -e -r $recipient"));

What I get in return is "Parse error: syntax error, unexpected T_CONSTANT_ENCAPSED_STRING" for the first or second line. I wonder why? Could it be that the path to the binary is wrong?

I have tried using double quotes and changing the variables names.

Could you help please?

Thanks

Well.. there's no real syntax error in the code you posted... can you show us more code above and below that snippet?

I use this to encrypt a file:

HOME=$home_dir USER=$user $gpg_path --quiet --no-secmem-warning --always-trust --armor -r [e-mail] --encrypt-files $sourcefile

and this to encrypt a string:

echo $encryptme | HOME=$home_dir USER=$user $gpg_path " . '--quiet --no-secmem-warning --encrypt --always-trust --armor ' . "--recipient $recipient
