推荐答案

有可能你必须在你的PHP文件之一年底一些空白。这是一个pretty常见的问题，如果您使用结束标记＆GT;

Likely you have some whitespace at the end of one of your PHP files. It is a pretty common problem if you use the closing tag ?>.

您会希望您的搜索code文件并寻找＆GT; 与后一个换行符。关闭标签后得到的任何输出到浏览器。

You'll want to search your code files and look for a ?> with a newline character after it. Anything after a closing tag gets output to the browser.

作为一种习惯，我不使用在code文件结束标记因为这个原因，因为它们不是由PHP间preTER必需的。一些编码标准推荐这一点。那里是PHP code后/间额外的输出，我只使用它们的模板文件。

As a habit, I don't use closing tags in code files for this reason, as they are not required by the PHP interpreter. Some coding standards recommend this as well. I only use them in template files where there is additional output between/after the PHP code.
