PHP Unicode codepoint to character

Question

I would like to convert Unicode codepoint to character. Here is what I have tried:

$point = dechex(127468);  // 1f1ec

echo \"\\u{1f1ec}\";         // this w         


        

Answer 1

You don't need to convert integer to hexadecimal string, instead use IntlChar::chr:

echo IntlChar::chr(127468);

Directly from docs of IntlChar::chr:

Return Unicode character by code point value

Answer 2

Actually find the solution after several hours:

$unicode = '1F605'; //                                                                    

                                                        
            

Answer 3

A similar problem occurs when you want to get a floating point number, say, 12e-4, concatenating pieces. The parsing is done too early in the compiler to allow it. You probably can, however, use eval() to do so. Yuck.
