I have updated php5 to php7.4 now Facing probelm with TCPDF as it was working properly with php5. Now I am facing two problems as given below

  1. Message: "continue" targeting switch is equivalent to "break". Did you mean to use "continue 2"?
    Filename: Tcpdf/Tcpdf.php
    Line Number: 17774
  2. Message: chr() expects parameter 1 to be int, string given
    Filename: include/tcpdf_fonts.php
    Line Number: 1671

Kindly suggest me best solution as I'm not able to find solution of these bugs.

Thanks In Advance.

    I've got the solution for this problem don't know is this the best approach or not but it work.

    public static function unichr($c, $unicode=true) {
        if(is_numeric($c))
        {
            if (!$unicode) {
                return chr($c);
            } elseif ($c <= 0x7F) {
                // one byte
                return chr($c);
            } elseif ($c <= 0x7FF) {
                // two bytes
                return chr(0xC0 | $c >> 6).chr(0x80 | $c & 0x3F);
            } elseif ($c <= 0xFFFF) {
                // three bytes
                return chr(0xE0 | $c >> 12).chr(0x80 | $c >> 6 & 0x3F).chr(0x80 | $c & 0x3F);
            } elseif ($c <= 0x10FFFF) {
                // four bytes
                return chr(0xF0 | $c >> 18).chr(0x80 | $c >> 12 & 0x3F).chr(0x80 | $c >> 6 & 0x3F).chr(0x80 | $c & 0x3F);
            } else {
                return '';
            }
        }
    }

    In the file include/tcpdf_fonts.php, I validate $c to make sure only numeric is allow.
