If you want to use hebrevc with english,
just use strrev.
(PHP 4, PHP 5)
hebrevc — 将逻辑顺序希伯来文（logical-Hebrew）转换为视觉顺序希伯来文（visual-Hebrew），并且转换换行符
$max_chars_per_line= 0 ] )
本函数与hebrev() 一样，唯一的区别是 本函数会额外将换行符(\n)转换为"<br>\n"。
Beware of English use!
I was working on a little project, and used hebrevc to reverse Hebrew in a loop. The hebrevc function got a variable as an argument. Sometimes the variable was pure English and sometimes it was hebrew.
Suddenly I found out that the English too was cut with BR tags, which made it look funny - the last line was the first.
If you're going to use that function in mixed text, don't forget to check the language before using the function.
