PHP page to UTF-8 Chinese code garbled solution _php Tips

For garbled this problem almost all of the PHP developers have encountered, we are mainly introduced below the PHP file garbled and garbled page.

PHP page UTF-8 encoding problem
1. Add a line to the beginning of the code:
Header ("Content-type:text/html;charset=utf-8");
2.PHP File Encoding problem
Click on the Editor's menu: "File"-> "Save As", you can see the current file encoding to ensure that the file is encoded as: UTF-8,
If it is ANSI, you need to change the encoding to: UTF-8.
3.PHP file Header BOM problem:
The PHP file must not have a BOM label
Otherwise, the session cannot be used, and there is a similar hint:
Warning:session_start () [Function.session-start]: Cannot send session cache Limiter-headers already sent
This is because, in the execution of Session_Start (), the entire page can not have output, but when the previous PHP page exists BOM label, PHP to this BOM label as output, so it went wrong!
So php page must delete BOM label!!!
How to delete this BOM label:
1. You can open the file with Dreamweaver and save it again, that is, you can remove the BOM label!
2. You can open the file with EditPlus, and in the menu "preferences"-> "file"-> "UTF-8 identity", set to: "Always delete signature",
Then save the file, that is, you can remove the BOM label!
4.PHP when saving files as an attachment, the UTF-8 encoding problem:
PHP as an attachment to save the file, file name must be GB2312 code, otherwise, if the file name in Chinese, will be displayed garbled:
If your PHP itself is a UTF-8 encoded file, you need to turn the filename variable from UTF-8 to GB2312:
iconv ("UTF-8", "GB2312", "$filename");
Using program to instance character interception method

function Utf8_substr ($str, $len) 
{for 
($i =0; $i < $len; $i + +) 
{ 
$temp _str=substr ($str, 0,1); 
if (Ord ($temp _str) > 127) { 
$i + +; 
if ($i < $len) { 
$new _str[]=substr ($str, 0,3); 
$str =substr ($STR, 3); 
} 
}else { 
$new _str[]=substr ($str, 0,1); 
$str =substr ($STR, 1); 
} 
return 
join ($new _str);
