This might work for unicode strings:
<?php
$s = iconv("ISO-8859-8", "UTF-8", hebrev(iconv("UTF-8", "ISO-8859-8", $s)));
?>

(PHP 4, PHP 5, PHP 7)
hebrev — 将逻辑顺序希伯来文（logical-Hebrew）转换为视觉顺序希伯来文（visual-Hebrew）
$hebrew_text
[, int $max_chars_per_line = 0
] ) : string将逻辑顺序希伯来文（logical-Hebrew）转换为视觉顺序希伯来文（visual-Hebrew）
函数将会尝试避免破坏单词。
hebrew_text逻辑顺序希伯来文字符串。
max_chars_per_line可选参数，表示每行可返回的最多字符数。
返回视觉顺序字符串。

From my experience in using hebrev text in HTML, I prefer using
<html dir="rtl" lang="he">
over mentioned PHP functions. It works perfectly with IE 6 ... needs some tweaking in Mozilla though.
I found this site http://tlt.its.psu.edu/suggestions/international/web/tips/align.html useful.
The hebrev function changes the string order to RTL.
Use fribidi_log2vis insted if you need LTR text direction
$text = fribidi_log2vis($text,FRIBIDI_LTR, FRIBIDI_CHARSET_CP1255)
hebrev() changes the flow of any Hebrew characters in a string from right-to-left to left-to-right.
It only affects characters within the range of ASCII 224-251 (except for punctuation).
