help with utf-8 BOM's and smarty

[skmd]

hi everyone,

i'm new to smarty templates and its really nice, but one thing i need to add.
i need to add this function to eliminate BOM's from templates before start compiling .

PHP Code:

function removeBOM($str=""){
        if(substr($str, 0,3) == pack("CCC",0xef,0xbb,0xbf)) {
                $str=substr($str, 3);
        }
        return $str;
} 


I suppose it must be somewhere in "fetch()" but I cant figure exactly where to put this function to work properly. can anyone help me with that??

I am looking at Smarty v2.6.19 (most recent version).

Open Smarty.class.php and scroll to the method _read_file() on line 1707:

PHP Code:

    /**
     * read in a file
     *
     * @param string $filename
     * @return string
     */
    function _read_file($filename)
    {
        if ( file_exists($filename) && ($fd = @fopen($filename, 'rb')) ) {
            $contents = '';
            while (!feof($fd)) {
                $contents .= fread($fd, 8192);
            }
            fclose($fd);
            return $contents;
        } else {
            return false;
        }
    } 


Replace it with this one:

PHP Code:

    /**
     * read in a file
     *
     * @param string $filename
     * @return string
     */
    function _read_file($filename)
    {
        if ( file_exists($filename) && ($fd = @fopen($filename, 'rb')) ) {
            $contents = '';
            while (!feof($fd)) {
                $contents .= fread($fd, 8192);
            }
            fclose($fd);
            $contents = removeBOM( $contents ); // customization: remove byte-order marks
            return $contents;
        } else {
            return false;
        }
    } 


Untested, but it should do what you're looking to accomplish.
