PHP $ _POST不需要重音 [英] PHP $_POST doesn't take accents

问题描述

这个问题已解决，请查看我的答案以查看解决方案 m试图通过HTML提交带有重音字母的文本到POST页面，问题是重音字母被转换为不可读的字符。

p>我有这样的表单：

 < form action =page.phpmethod =POST> 
< input type =textareaid =text1name =text1/> 
< input type =submitvalue =Send/> 
< / form> 
  

然后，在page.php中：

  echo $ _POST ['text1']; 
  

问题是如果我输入àèìòù在我的textarea然后我提交表单，我得到这个输出：

 ÃèìòùÃ$ 
  

我的下一步是将带重音的字母转换为带有 htmlentities（$ _ POST ['text1' ] 但我需要 $ _ POST 给我正确的字母。

在页头中，我已经有了

 < meta http-equiv =Content-Typecontent =text / html; charset = utf-8/> 
  

如何解决这个问题？

编辑

我尝试过

< input type =textareaid = 
< / form> 
< / code> 

并没有解决它

编辑2

还尝试添加

 < meta charset ='utf-8'> 
  

添加到我的文档头部，并且不起作用

编辑3

我尝试在第二页上将我的字符集设置为UTF-8，并且

  echo $ _POST ['text1']; 
  

显示正确的结果。

我看到这个问题是我使用htmlentities，与此代码

  echo htmlentities（$ _ POST ['text1']）; 
  

我得到

 &安培; Atilde;&安培; NBSP;&安培; Atilde;&安培; UML;&安培; Atilde;&安培;不;&安培; Atilde;&安培; SUP2;&安培; Atilde;&安培; SUP1; 
  

实际产出

解决方案
好的，我终于解决了它。即使我设置字符集，无论是用PHP头部设置它还是 
 
 
  header（'Content-Type：text / html;字符集= UTF-8' ）; 
  
或HTML元标记
 < meta http-equiv =Content-Typecontent =text / html; charset = utf-8/> 
  
并将我的文件保存为UTF-8，但它无效。
 
 
 
输入àèìòù，然后使用 htmlentities 处理它总是导致
 & Atilde;& nbsp;& Atilde;& uml;& Atilde;& not& Atilde;& amp ; SUP2;&安培; Atilde;&安培; SUP1; 
  
在可读字符中，是： 
 
 
 ÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃÃ改变了这个：
  echo htmlentities（$ _ POST ['text1']）; b 
 
 
 
 
 
  echo htmlentities（$ _ POST ['text1']，ENT_QUOTES，UTF-8）; 
  
并且一切正常，我可以打印出真实的输入。
 
 
 
谢谢大家的帮助！

I'm trying to add to my DB a text with accented letters through an html form that submits with POST to a PHP page, the problem is that accented letters are converted to unreadable characters.

I have this form:
<form action="page.php" method="POST">
    <input type="textarea" id="text1" name="text1" />
    <input type="submit" value="Send" />
</form>
And then, in page.php:
echo $_POST['text1'];
The problem is that if i input àèìòù in my textarea and then i submit the form, i get this output:
à èìòù
My next step would be convert accented letters to html entities with htmlentities($_POST['text1'] but i need $_POST to give me the correct letters.

Note: in the page head i already have
<meta http-equiv = "Content-Type" content = "text/html; charset=utf-8" />
How can i fix this?

EDIT

I tried with
<form action="page.php" method="POST" accept-charset="UTF-8">
    <input type="textarea" id="text1" name="text1" />
    <input type="submit" value="Send" />
</form>
And it didn't solve it

EDIT 2

Also tried with adding
<meta charset='utf-8'>
to my document's head, and it doesn't work

EDIT 3

I tried with setting my charset as UTF-8 on the second page too, and
echo $_POST['text1'];
displayed the correct result.

I saw that the problem is whe i use htmlentities, with this code 
echo htmlentities($_POST['text1']);
I get 
&Atilde;&nbsp;&Atilde;&uml;&Atilde;&not;&Atilde;&sup2;&Atilde;&sup1; 
Which actually outputs 
à èìòù 
even if i set charset in my meta-tags and header too. Does anyone know how can i solve it?
解决方案
Ok, i finally solved it. Even if i was setting charset, no matter if setting it with PHP header
header('Content-Type: text/html; charset=utf-8');
or with HTML meta tag
<meta http-equiv = "Content-Type" content = "text/html; charset=utf-8" />
and saving my file as UTF-8, it didn't work.

Entering àèìòù and then processing it with htmlentities was always resulting in 
&Atilde;&nbsp;&Atilde;&uml;&Atilde;&not;&Atilde;&sup2;&Atilde;&sup1; 
That, in "readable" characters, is:
à èìòù
I just changed this:
echo htmlentities($_POST['text1']);
to this:
echo htmlentities($_POST['text1'], ENT_QUOTES, "UTF-8");
and everything worked, i get my real input printed out.

Thank you all for your help!
