Character encoding in PHP: gb2312 vs UTF-8

Today, I wrote a paragraph according to the book.CodeThe purpose of the code is to split the string into Arrays Using the str_split () function. It is easy to say in English, but there is a problem when splitting the Chinese character (two Chinese characters and one array unit --

Check the Code:

 <!  Doctype HTML public "-// W3C // dtd html 4.01 transitional // en" "http://www.w3.org/TR/html4/loose.dtd"  >  
  <  Html  >  
  <  Head  >  
  < Meta  HTTP-equiv  = "Content-Type"  Content  = "Text/html; charsets = UTF-8"     />  
  <  Title  >  New Document  </  Title  >  
  < Meta  Name  = "Author"  Content  = ""  />  
  <  Meta  Name  = "Keywords"  Content  = ""  />  
  <  Meta Name  = "Description"  Content  = ""  />  
  <  Link  REL  = "Stylesheet"  Type  = "Text/CSS"  Href  = ""     />   
 </  Head  >  

  <  Body  >  
  <?  PHP
$ String1 = "I Am a phper ";
$ String2 = "This book is a blue ocean strategy ";
Print_r (str_split ($ string1 ));
Echo "<br/> ";
Print_r (str_split ($ string2, 4 ));
  ?>  
  </  Body >  
  </  Html  > 

Test result output as expected --Chinese garbled characters

Why? Why? Why? Why? What is garbled code? What is garbled? Explain to me what is % & garbled!

Because English without garbled characters, only Chinese garbled characters, first of all think of the encoding problem, so suddenly think of the UTF-8 encoding is UTF-8 needs 3 bytes, dead horse as a doctor!

Therefore, print_r (str_split ($ string2, 4); 4 in this sentence is replaced6, So -- view the result

Similarly, you can also try to change the UTF-8 of charset encoding to gb2312, because unicode encoding requires 2 bytes, so the gb2312 encoding can save 1/3 of the space than the UTF-8, but if you want to be compatible with other languages of Traditional Chinese, Korean, and Japanese, you need to use UTF-8.

By the way, I found the first dynamic music and shared it with me:

-It's OK?

-It's OK!
