string bom ( )Return the byte order mark (BOM) Unicode character used to signal the byte order of a text file or a stream. The BOM character may also indicate which of the several Unicode representations the text is encoded in. BOM use is optional, and, if used, must appear at the ...
但它不起作用。如何将这些unicode转换为utf8字符串? 您可以使用url_decode获得以下结果: <?php $string = '%d8%b7%d8%b1%d8%a7%d8%ad%db%8c-%d8%a7%d9%be%d9%84%db%8c%da%a9%db%8c%d8%b4%d9%86-%d9%81%d8%b1%d9%88%d8%b4%da%af%d8%a7%d9%87%db%8c'; ...
$string='沈唁 ';var_dump(trim($string));var_dump(preg_replace("/^[\s\0]+|[\s\0]+$/u",'',$string)); 如果你觉得是一致的,那么就是大错特错了。 在日常工作中,经常需要处理字符串。其中一种常用的情况是,需要删除字符串两端的空白字符,这就是trim()函数原本的作用。
For this reason, PHP does not seem to be able to output Unicode CSV file for Microsoft Excel. Solving this problem is quite simple: just put BOM infront of UTF-16LE string.Example:$unicode_str_for_Excel = chr(255).chr(254).mb_convert_encoding( $utf8_str, 'UTF-16LE', 'UTF-8')...

Note to Windows users:This charset string replacement (from latin1 to UTF-8) can also be done using find-and-replace in WordPad (or some other text editor, such as vim). Be sure to save the file just as it is though (don’t save it as unicode txt file!). ...
然而大多数字符串的函数,像strpos()和strlen(),确实需要特别的对待。这些函数通常都有一个冠以mb_*开头的对等函数:比如,mb_strpos()和mb_strlen()。这些mb_*开头的字符串操作函数来源于Multibyte String Extension,它专门为操作 Unicode 字符串而特别进行了设计。
