O PHP não pode localizar sua função getRecords(). Você incluiu o arquivo em que esta função está definida?
Editar:
Você deve realmente procurar proteger seus dados postados e apenas a limpeza geral do código. É melhor usar as funções que o mysql fornece diretamente, em vez de envolvê-las em funções que são utilizáveis apenas para uma situação.
E:por que diabos você está construindo toda a sua tabela Employeeinfo toda vez, ou pelo menos verificando se ela existe? Isso deve ser algo que você faz uma vez e esquece. Em seguida, exclua esse código, porque é confuso.
Você deve pensar em como tudo isso deve funcionar logicamente antes de mergulhar. Isso é basicamente um sistema de gerenciamento de funcionários? Parece que você deseja:Adicionar novos funcionários, pesquisar funcionários, editar funcionários e excluir funcionários. Aqui está uma implementação básica, está faltando o recurso para adicionar um funcionário. Eu não testei isso, mas espero que aponte na direção certa:

Novamente, isso ainda é básico, e esse tipo de coisa deve ser implementado em uma classe php. Isso está usando PDO, portanto, se os detalhes do banco de dados mudarem, basta alterar o dbfactory.php e pronto.
Se eu pudesse voltar e mudar uma coisa sobre como começar a aprender PHP, seria aprender PDO em vez das funções de consulta mysql obsoletas como você está usando.
Esta não é de forma alguma uma implementação perfeita, como eu disse, tudo deve ser classificado e a lógica separada da apresentação; Mas é um começo!
Feliz aprendizado!
