三个字给您:
字节顺序标记(BOM)
这就是ISO-8859-1中UTF-8 BOM的表示形式。您必须告诉编辑器不要使用BOM表,或使用其他编辑器将它们删除。
另一个答案所说的那样最好的办法是让PHP正确地正确解释BOM,因为您可以使用
mb_internal_encoding(),例如:
<?php //Storing the previous encoding in case you have some other piece //of pre sensitive to encoding and counting on the default value. $previous_encoding = mb_internal_encoding(); //Set the encoding to UTF-8, so when reading files it ignores the BOM mb_internal_encoding('UTF-8'); //Process the CSS files... //Finally, return to the previous encoding mb_internal_encoding($previous_encoding); //Rest of the pre... ?>
