If the optional regs parameter was specified, the function returns the byte length of matched part, and the array regs will contain the substring of matched string. The function returns 1 if it matches with the empty string. If no matches are found or an error happens, FALSE will be returned.

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");


?>
