无法使用PHP在MYSQL数据库中存储阿拉伯语 [英] Unable to Store Arabic in MYSQL database using PHP
问题描述
过去的几个小时，我一直在寻找解决方案，但未能做到.我已经在Internet和此论坛上尝试了所有可能的解决方案，但似乎没有任何效果.这是问题所在.
我想存储阿拉伯数据，用户将在mysql数据库中键入或粘贴到表单的文本区域中.该网站为阿拉伯语，表格仅包含该文本区域.
重要点:
该网站正确显示了静态阿拉伯语内容. utf8字符集在整个网站中使用.所以这不是问题.
表(home)和内容字段(content)都设置为utf8_unicode_ci排序规则，因此也不是问题.
Form设置为accept-charset ='utf-8'，所以这也不是问题.
当我在表中使用phpMyAdmin插入阿拉伯文本时，我一点都没有问题.
事实上，当在网站上检索到表中的阿拉伯文本(通过phpMyAdmin输入)时，它会完美显示.
但是，一旦在文本区域中输入阿拉伯数据并将其发送到DB以使用插入查询数据进行存储，它就会转换为????
我正在使用
mysql_query("SET NAMES 'utf8'");
mysql_query('SET CHARACTER SET utf8');
在连接之后，所以这根本不是问题.正如我之前说的，可以正确检索数据.我已经上传了两张图片.展示我的问题.
我真的被困在这里，正如您所看到的，我也已经采取了所有可能的步骤来解决此问题，但是这种行为确实很奇怪.请帮忙.
存储
我用于将数据插入db的代码是:
$content=$_POST["content"];
echo $content;
$sql="update home set content='$content'";
$result=mysql_query($sql) or die(mysql_error());
您可以看到第二个echo语句.我添加了它来调试问题.数据在此回波中完美显示.我猜想查询中出现了问题.
服务器端的所有代码看起来都正常运行.当浏览器将表单提交回服务器，然后数据错误或被错误解释时，似乎发生了错误.
1)请确认安装了多字节扩展名.如果您不这样做，则PHP可能无法正确解释浏览器中的字符. http://php.net/manual/zh/book.mbstring.php
2)您能否再次检查该页面是否实际上已被浏览器拾取为UTF8.浏览器可能不确定页面所在的字符集，但仍在正确显示阿拉伯字符，因为它正在猜测如何显示它们.所以首先.
在您的HTML中，添加以下元标记:
还要在脚本顶部添加此PHP标头:
header("Content-Type:text/html; charset = UTF-8");
3)如果这些方法不起作用，可以使用Chrome中的开发人员工具或Firefox中的Firebug在浏览器中查看实际提交的表单.
例如我只是做了一个测试页，以将一些阿拉伯文本提交到服务器上的测试页.在请求中，我可以看到表单被编码为
Content-Length: 61
test=%26%231607%3B%26%231594%3B%26%231594%3B%26%231601%3B&go=
将文本拆分为可以看到的单个字符
%26
%231607
%3B
%26
%231594
%3B
%26
%231594
%3B%26
%231601
%3B
即阿拉伯字符已为我正确编码-也许您会看到一些不同的东西.
I have been trying to find a solution for past few hours but unable to do so. I have tried each and every possible solution on the Internet and this forum but nothing seems to be working. Here is the problem .
I want to store arabic data that user will type or paste in the textarea of form in mysql database. The website is arabic and form only contains this one textarea.
Important Points:
The website is displaying static arabic content correctly. utf8 charset is used throughout the website. So it is not a problem.
The table (home ) and the content field(content) are both set to utf8_unicode_ci collation so it is not a problem either.
Form is set to accept-charset='utf-8' so that's not a problem either.
When I insert arabic text using phpMyAdmin in the table I don't have any problem at all with it.
In fact when arabic text (entered through phpMyAdmin) in the table is retrieved on the website it shows perfectly.
But as soon as arabic data is entered in text area and sent to DB to be stored using insert query data transforms into ????
I am using
mysql_query("SET NAMES 'utf8'");
mysql_query('SET CHARACTER SET utf8');
After Connection so it is not a problem at all. As I said earlier the data is retrieved all right. I have uploaded the two images. Demonstrating my problem.
I am really stuck here and as you can see I have taken all the steps possible to solve this as well but this behavior is really weird. Please help.
The code I am using to insert the data into db is:
$content=$_POST["content"];
echo $content;
$sql="update home set content='$content'";
$result=mysql_query($sql) or die(mysql_error());
You can see the second echo statement. I added it to debug the problem. Data is shown perfectly in this echo. The problem rises in the query I suppose.
It looks like all the code on the server side is working properly. The error seems to be happening when the browser submits the form back the server and then either the data is wrong or is mis-interpreted.
1) Please can you confirm that you have the Multi-Byte extension installed. If you don't then PHP will probably be failing to interpret the characters from the browser correctly. http://php.net/manual/en/book.mbstring.php
2) Can you double-check that the page is actually picked up as UTF8 by the browser. It is possible that the browser isn't sure what character set the page is in, but is still displaying the Arabic characters correctly because it's guessing how to display them. So first.
In your HTML, add this meta tag:
Also add this PHP header at top of the script:
header("Content-Type: text/html;charset=UTF-8");
3) If those don't work please can you look at the actual form submission in the browser, either using the developer tools in Chrome or Firebug in Firefox to see exactly what is being submitted.
e.g. I just did a test page to submit some Arabic text to a test page on my server. In the request I can see the form is encoded as
Content-Length: 61
test=%26%231607%3B%26%231594%3B%26%231594%3B%26%231601%3B&go=
Splitting the text into individual characters I can see
%26
%231607
%3B
%26
%231594
%3B
%26
%231594
%3B%26
%231601
%3B
i.e. the Arabic characters are being encoded correctly for me - perhaps you would see something different.
