To convert the utf16 or utf8 decimal values (utf-8 can translate both encodings) to ascii characters using mb_ord, follow these steps:
Starting value:
1_Zvpxs4pf
Value converted to decimal value utf-16 or utf-8 (see ascii coding table):
49,95,90,118,112,120,115,52,112,102
recovery with mb_ord:
use: $ char = mb_chr ($ decimalValue, 'UTF-8');
return the correct character;
1, _, Z, v, p, x, s, 4, p, f
example:
$ start_String = 1_Zvpxs4pf;
$ start_String_to_Decimal = 49959011811212011552112102;
(decimal value of each character add in an array);
$ tab = [49, 95, 90, 118, 112, 120, 115, 52, 112, 102];
$ size = sizeof ($ tab);
$ tmpStr = '';
for ($ i = 0; $ i <$ size; $ i ++)
{
$ tmpStr. = mb_chr ($ tab [$ i], 'UTF-8');
}
echo $ tmpStr;
1_Zvpxs4pf
