iconv

My project works fine on localhost but not working online and this is the error: Fatal error: Call to undefined function Symfony\Polyfill\Mbstring\iconv_strlen() in /home/stram/public_html/vendor/symfony/polyfill-mbstring/Mbstring.php on line 338 I googled it and I found that I need to install the PHP extension iconv . The problem that I'm using a VPS and when I went to the list of available PHP extensions I didn't found this extension ! Thnx in advance. Symfony provides an iconv-polyfill for cases like that. Just add it as requirement to your project, and you should be fine: composer require

iconv 中文截断问题的解决方法 今天做了一个采集程序，原理很简单，使用curl方法把对方页面的html获取分析，然后正则提取需要的数据并保存在数据库。 由于对方页面是GB2312编码，而本地使用的是UTF-8编码。因此在采集后需要进行编码转换。 使用了 iconv 方法进行编码转换 [php] view plain copy iconv — 字符串按要求的字符编码来转换 string iconv ( string $in_charset , string $out_charset , string $str ) 将字符串 str 从 in_charset 转换编码到 out_charset 。 转换的方法很简单，直接使用iconv方法就可以了 [php] view plain copy <?php $content = iconv( 'GB2312' , 'UTF-8' , $content ); // $content为采集到的内容 ?> 试验了几个页面，都能正常采集。但在之后的采集中，有几个页面采集不完整。 一开始考虑是否正则有错，检查后排除此问题。经过排查，发现经过iconv转码后的内容比采集的内容少了一大段。 查看apache log，看到提示： Notice: iconv(): Detected an illegal character in input string

I have a Ruby script that generates a UTF8 CSV file remotely in a Linux machine and then transfers the file to a Windows machine thru SFTP. I then need to open this file with Excel, but Excel doesn't get UTF8, so I always need to open the file in a text editor that has the capability to convert UTF8 to ANSI. I would love to do this programmatically using Ruby and avoid the manual conversion step. What's the easiest way to do it? PS: I tried using iconv but had no success. ascii_str = yourUTF8text.unpack("U*").map{|c|c.chr}.join assuming that your text really does fit in the ascii character set

可以将文章内容翻译成中文,广告屏蔽插件可能会导致该功能失效(如失效，请关闭广告屏蔽插件后再试): 问题: I don't know Ruby but want to run an script where: D:/Heather/Ruby/lib/ruby/2.0.0/rubygems/core_ext/kernel_require.rb:45:in `require': cannot load such file -- iconv (LoadError) it works somehow if I comment iconv code but it will be much better if I can recode this part: return Iconv.iconv('UTF-8//IGNORE', 'UTF-8', (s + ' ') ).first[0..-2] without iconv . Maybe I can use String#encode here somehow? 回答1: Iconv was deprecated (removed) in 1.9.3. You can still install it. Reference Material if you unsure: https://rvm.io/packages/iconv/ However

I'm reading data from a remote source, and occassionally get some characters in another encoding. They're not important. I'd like to get get a "best guess" utf-8 string, and ignore the invalid data. Main goal is to get a string I can use, and not run into errors such as: Encoding::UndefinedConversionError: "\xFF" from ASCII-8BIT to UTF-8: invalid byte sequence in utf-8 I thought this was it: string.encode("UTF-8", :invalid => :replace, :undef => :replace, :replace => "?") will replace all knowns with '?'. To ignore all unknowns, :replace => '' : string.encode("UTF-8", :invalid => :replace,

话不多说上干活 public function downloadMatchDataAction() { // 要下载的信息 $user = new UserModel(); $sql = "SELECT id,name,age,sex ORDER BY age DESC LIMIT 0,100"; $list = $user->query($sql);//这里可以理解为查出来的二维数组 $th = ['编号','姓名','年龄','性别']; $datas = array();//定义空数组，用来装自己想要的数据格式 foreach($list as $key => $val){ $datas[$key][] = $val["id"]; $datas[$key][] = $val["name"]; $datas[$key][] = $val["age"]; $datas[$key][] = $val["sex"]; } //解释一下这个循环，$datas为二维数组，$key为$list的键，将$list里面的键变为$datas里面的键最后再给这个键附上我刚才查询的值 $this->outCsvTableAction('match',$th,$datas);//这里注意，指的是调用累内该方法 exit;//我这里我选择了退出因为导出并下载我已经完成了，做完以后还需要做记录请自行修改。

linux系统里提供的文件转化编码的命令iconv，例如： iconv -t utf-8 -f gb2312 -c test.xml > text_UTF8.xml 1 -f 源编码 -t 目标编码 -c 忽略无法转换的字符 如果想批量转换，只需要执行如下两行命令即可： find folder -type d -exec mkdir -p utf/{} \; find floder -type f -exec iconv -f GB2312 -t UTF-8 {} -o utf/{} \; 1 2 这两行命令将folder目录下的文件由GB2312编码转换为UTF-8编码，目录结构不变，转码后的文件保存在utf/folder目录下。 来源：博客园 作者： mingzhang 链接：https://www.cnblogs.com/mingzhang/p/11653170.html

使用iconv之前, 先了解一下utf-8编码和Unicode字符集: https://blog.csdn.net/zhusongziye/article/details/84261211 再了解一下gbk 来源： https://www.cnblogs.com/bneglect/p/11751462.html
