mb_ereg — Regular expression match with multibyte support

Beschreibung

int mb_ereg ( string $pattern , string $string [, array $regs ] )

Executes the regular expression match with multibyte support.

Parameter-Liste

pattern

The search pattern.

string

The search string.

regs

Contains a substring of the matched string.

Rückgabewerte

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

Anmerkungen

Das interne Encoding oder das mit mb_regex_encoding() festgelegte Zeichenencoding wird als Zeichenencoding für diese Funktion genutzt.

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");
?>
