Curl inside is time consuming and troubled

Question

I need to test all user accounts of a db on text area am utilizando the script

function informacoes(){
   $linhas = explode("\n", $_POST['conta']);
   $count = count($linhas) -1;

    for($i=0 ; $i<= $count; $i++) {
        $conta = explode("|", $linhas[$i]);

        $email = $conta[0];
        $senha = $conta[1];

        checker($email, $senha);
    }
}

Function Checker :

function checker ($email, $senha) {
  // todo o sistema do curlopt esta aqui
  // exemplo
  if(strpos($data, 'Erro":false') !== false){
      echo "conta ativa";
  }
}

The problema is that it stays muito lerdo and it doesn’t work as expected. Another problema it is also that only faz echo quando todas as contas já foram testadas

Analyze: case the text area has only 1 account the script is done as expected.
