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
