For anyone having trouble trying to detect the encoding of a string because PHP provides no easy way
to see the characters (and byte values) of a string, here's a function that returns the
characters and byte values for the ASCII and UTF-8 encodings:
<?php
function hex_chars($data) {
$mb_chars = '';
$mb_hex = '';
for ($i=0; $i<mb_strlen($data, 'UTF-8'); $i++) {
$c = mb_substr($data, $i, 1, 'UTF-8');
$mb_chars .= '{'. ($c). '}';
$o = unpack('N', mb_convert_encoding($c, 'UCS-4BE', 'UTF-8'));
$mb_hex .= '{'. hex_format($o[1]). '}';
}
$chars = '';
$hex = '';
for ($i=0; $i<strlen($data); $i++) {
$c = substr($data, $i, 1);
$chars .= '{'. ($c). '}';
$hex .= '{'. hex_format(ord($c)). '}';
}
return array(
'data' => $data,
'chars' => $chars,
'hex' => $hex,
'mb_chars' => $mb_chars,
'mb_hex' => $mb_hex,
);
}
function hex_format($o) {
$h = strtoupper(dechex($o));
$len = strlen($h);
if ($len % 2 == 1)
$h = "0$h";
return $h;
}
?>
