php中include require utf-8文件时顶部产生空行
include()产生一个警告而require()则导致一个致命错误,换句话说,如果想在遇到丢失文件时停止处理页面就用require(),include()就不是这样,脚本会继续运行,同时也要确认设置了合适的include_path,注意在 PHP 4.3.5之前,包含文件中的语法错误不会导致程序停止.
关于include require utf-8文件时顶部产生空行解决办法
php中使用require函数加载utf8文件的时候会产生一个空行,这是由于在windows环境下编辑文件的时候会产生几个识别utf8的字符,这些字符称为Unicode签名(BOM).
特别是用记事本将网页文件由ANSI另存为UTF-8时易出现.
解决办法:
1. 可以通过在Dreamweaver中按Ctrl+J,在标题与编码中去除此选项.
2. 用EditPlus将文件另存为UTF-8,无BOM文件.
