[php][Resolved] ERR_CONTENT_DECODING_FAILED

To solve the problem, these things i did :

1) Turn on zlib.output_compression in your php.ini, default is Off, edit it to On.

2) If you using notepad++ for coding, save the file cause problem without BOM.

3) If after finishing (1)  and (2) still is not work, check your php syntax. For me case it's strange that i use return syntax to replace echo , the problems solved.
