You can use openssl_pkey_new() of php to generate private key which is documented in detail here For public key get the details using $all_values = openssl_pkey_get_details($privateKey); function and get public key out of it like $all_values['key'];

Update:

or there is also another post on stackoverflow stating the same thing:here

i am getting this error " openssl_pkey_get_details() expects parameter 1 to be resource, boolean given in " – Manpreet Oberoi Sep 12 '16 at 09:36
Can you please paste the code you are using to generate the key. As stated in the error you must be using a boolean type of parameter to pass to the function which should be resource – MKB Sep 12 '16 at 09:40
