错误：“无法发送会话缓存限制器”与编码相关

发布于 2024-11-29 22:33:04 字数 598 浏览 1 评论 0原文

我开始遇到编码问题，似乎 Notepad++ 以某种方式更改了编码或其他内容。无论如何，所有文件都以 UTF-8 编码，但我检查了一下，有些文件更改为没有 BOM 的 UTF-8。将其更改为 UTF-8 解决了特殊字符问题。

"Tageá" 更改为 "Tageá" 但我开始收到错误：

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/02/6945202/html/usuario/index.php:1) in /home/content/02/6945202/html/usuario/index.php on line 1

这是第 1 行：

<? session_start(); ?>

我不明白为什么会遇到此问题，因为使用没有 BOM 的 ANSI 或 UTF-8 页面显示没有错误。

可能是什么问题？谢谢

I'm started having problems with the encoding, it seems that somehow Notepad++ changed the encoding or something. Anyway all files where encoded in UTF-8, but I checked and some changed to UTF-8 without BOM. Changing one to UTF-8 fixed the special characters issue.

"TageÃƒÂ¡" changed to "Tageá" but I started getting an error:

Warning: session_start() [function.session-start]: Cannot send session cache limiter - headers already sent (output started at /home/content/02/6945202/html/usuario/index.php:1) in /home/content/02/6945202/html/usuario/index.php on line 1

This is line 1:

<? session_start(); ?>

I don't understand why I'm having this issue, since using ANSI or UTF-8 without BOM the page shows with no errors.

What can be the problem? Thanks

好的，尝试使用这个函数来转换字符串，将文件保存为没有 bom 的 utf-8 。

<?php
session_start();
function charset_decode_utf_8 ($string) {
  /* Only do the slow convert if there are 8-bit characters */
    /* avoid using 0xA0 (\240) in ereg ranges. RH73 does not like that */
    if (! ereg("[\200-\237]", $string) and ! ereg("[\241-\377]", $string))
        return $string;

    // decode three byte unicode characters
    $string = preg_replace("/([\340-\357])([\200-\277])([\200-\277])/e",     
    "'&#'.((ord('\\1')-224)*4096 + (ord('\\2')-128)*64 + (ord('\\3')-128)).';'",    
    $string);

    // decode two byte unicode characters
    $string = preg_replace("/([\300-\337])([\200-\277])/e", 
    "'&#'.((ord('\\1')-192)*64+(ord('\\2')-128)).';'", 
    $string);

    return $string;
}
echo charset_decode_utf_8('TageÃƒÂ¡');
?>

ok try using this function to convert strings, save file as utf-8 without bom for this.

<?php
session_start();
function charset_decode_utf_8 ($string) {
  /* Only do the slow convert if there are 8-bit characters */
    /* avoid using 0xA0 (\240) in ereg ranges. RH73 does not like that */
    if (! ereg("[\200-\237]", $string) and ! ereg("[\241-\377]", $string))
        return $string;

    // decode three byte unicode characters
    $string = preg_replace("/([\340-\357])([\200-\277])([\200-\277])/e",     
    "'&#'.((ord('\\1')-224)*4096 + (ord('\\2')-128)*64 + (ord('\\3')-128)).';'",    
    $string);

    // decode two byte unicode characters
    $string = preg_replace("/([\300-\337])([\200-\277])/e", 
    "'&#'.((ord('\\1')-192)*64+(ord('\\2')-128)).';'", 
    $string);

    return $string;
}
echo charset_decode_utf_8('TageÃƒÂ¡');
?>
