For example, the utf8 encoding of the character "you" is "E4BDA0 ".
There is an array $ arr
$ Arr = array (chr (228), chr (189), chr (160 ));

How can we splice it into one piece so that it can print the character "you "?
To help share the binary php UTF-8 encoding:
------ Solution --------------------
$ Arr = array (chr (228), chr (189), chr (160 ));
Echo join ('', $ arr); // You
Foreach ($ arr as $ v) echo $ v;
For ($ I = 0; $ I

Echo pack ('H * ', 'e4bda0 ');
Echo hex2bin ('e4bda0 ');
