[RESOLVIDO]JSON data from server could not be parsed. This is caused by a JSON formatting error

Olá galera, a alguns dias atrás fiz um post perguntando como implementar um DataTable, pois bem: A implementação funcionou perfeitamente porém até então somente inserindo dados manualmente por . Ontem comecei a tentar trazer os dados do meu banco para o DataTable mas sem sucesso! Eu estou utilizando o método indicado no site do plugin ( http://datatables.net/release-datatables/examples/server_side/server_side.html ), porém ao abrir a página onde se encontra o DataTable ele me apresenta o seguinte erro: JSON data from server could not be parsed. This is caused by a JSON formatting error. Alguém ai sabe como resolver esse erro? Vou deixar abaixo meu html e meu arquivo JSon ( nesse código arquivo JSon é o server_processing.php):

Ps: não sei se esse erro se deve ao fato do arquivo JSon ser php, caso seja esse o motivo, teria como contornar esse problema?
