As I said, you coud use JSON rpc to create a wallet and and set password. But PHP and geth don't go well together, it will limit your app. I recommend going directly with web3.js, javascrio/jquery/nodejs.
For generating wallet thought JSON-RPC (pass sent over the network):
//create eth wallet supplying pass, return wallet address if created
function getethwallet($pass) {
$url = "http://node.ip:8545";
$data = array(
"jsonrpc" => "2.0",
"method" => "personal_newAccount",
"params" => array($pass),
"id" => "1"
);
$json_encoded_data = json_encode($data);
$ch = curl_init($url);
curl_setopt($ch, CURLOPT_CUSTOMREQUEST, "POST");
curl_setopt($ch, CURLOPT_POSTFIELDS, $json_encoded_data);
curl_setopt($ch, CURLOPT_RETURNTRANSFER, true);
curl_setopt($ch, CURLOPT_HTTPHEADER, array(
'Content-Type: application/json',
'Content-Length: ' . strlen($json_encoded_data))
);
$result = json_decode(curl_exec($ch));
curl_close($ch);
$parsed = $result->result;
return $parsed;
}
