The code below runs in a browser but not in the development environment of phpDesigner 8:
public function charCodeAt($str, $num) {
return $this->utf8_ord($this->utf8_charAt($str, $num));
}
public function utf8_ord($ch) {
$len = strlen($ch);
if($len <= 0) return false;
$h = ord($ch{0});
if ($h <= 0x7F) return $h;
if ($h < 0xC2) return false;
if ($h <= 0xDF && $len>1) return ($h & 0x1F) << 6 | (ord($ch{1}) & 0x3F);
if ($h <= 0xEF && $len>2) return ($h & 0x0F) << 12 | (ord($ch{1}) & 0x3F) << 6 | (ord($ch{2}) & 0x3F);
if ($h <= 0xF4 && $len>3) return ($h & 0x0F) << 18 | (ord($ch{1}) & 0x3F) << 12 | (ord($ch{2}) & 0x3F) << 6 | (ord($ch{3}) & 0x3F);
return false;
}
public function utf8_charAt($str, $num) {
return mb_substr($str, $num, 1, 'UTF-8');
}
I get the error message: "Fatal error - Call to undefined function mb_substr()"
Can anyone suggest how to get mb_substr() to work? When I installed phpDesigner 8 I don't recall seeing an option to include additional libraries of functions.
I have tried contacting the company but they have not provided a solution.
Thanks!
