Cleyverson, Esse problema que você reportou é comum mesmo. Inclusive, recomenda-se que, para arquivos de classe do PHP, o ideal é que não haja mesmo a tag de encerramento do PHP, que é opcional. Assim evita-se o espaço no final do arquivo.
Porém, o problema do cara foi outro. Eu não sei por que motivo, as vezes alguns editores colocam um caracter no início do arquivo, que o servidor web interpreta como um espaço, causando o erro como o reportado pelo Bruno. Nesse caso, não tem o que fazer a não ser abrir o arquivo num editor texto e remover o caracter ou criar outro arquivo. 2009/2/4 Cleyverson Costa <[email protected]>: > Eu Tive um problema parecido e o que fiz foi retirar o ?> do final de todos > os arquivos (libraries, helpers, models, controllers) > > Faça isso, acredito que resolverá.
