mb_ereg_search
Note that mb_ereg() does not support the \uFFFF unicode syntax but uses \x{FFFF} instead:
<?PHP
$text = 'Peter is a boy.'; // english
$text = 'بيتر هو صبي.'; // arabic
//$text = 'פיטר הוא ילד.'; // hebrew
mb_regex_encoding('UTF-8');
if(mb_ereg('[\x{0600}-\x{06FF}]', $text)) // arabic range
//if(mb_ereg('[\x{0590}-\x{05FF}]', $text)) // hebrew range
{
echo "Text has some arabic/hebrew characters.";
}
else
{
echo "Text doesnt have arabic/hebrew characters.";
}
?>

Executes the regular expression match with multibyte support, and returns 1 if matches are found.

I could easily remove any non Persian (Farsi) characters using this function, the range for Arabic and Persian are shared so this code could be used for Arabic too.
<?php mb_ereg_replace("[^-ۿ]","-",$string); ?>
This is the reference for finding the character range of Unicode languages:

Hebrew regex tested on PHP 5, Ubuntu 8.04.
Seems to work fine without the mb_regex_encoding lines (commented out).
Didn't seem to work with \uxxxx (also commented out).
<?php
echo "Line ";
//mb_regex_encoding("ISO-8859-8");
//if(mb_ereg(".*([\u05d0-\u05ea]).*", $this->current_line))
if(mb_ereg(".*([א-ת]).*", $this->current_line))
{
echo "has";
}
else
{
echo "doesn't have";
}
echo " Hebrew characters.<br>";
//mb_regex_encoding("UTF-8");
?>
