PHP怎么样把GBK编码格式的文件转换成UTF-8编码格式的文件


    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">咱们</span>在建站过程中,经常面对建站程序的编码<span style="color: black;">选取</span>,以Discuz! X3.5为例,官方<span style="color: black;">供给</span>了两个编码版本的程序,分别是Discuz_X3.5_SC_UTF8和Discuz_X3.5_SC_GBK,这是什么意思呢?<span style="color: black;">便是</span>Discuz! X3.5把文件编码和数据库编码转换<span style="color: black;">成为了</span>两个版本,一个UTF-8编码一个是GBK编码,<span style="color: black;">咱们</span>下载任何一个编码的程序,网站都能够正常<span style="color: black;">运用</span>!<span style="color: black;">那样</span>这两种编码各有什么区别呢?</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><strong style="color: blue;"><span style="color: black;"><a style="color: black;">分享一款免费虚拟主机,共享服务器资源</a></span></strong></span></p>
    <h2 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">1、</span>GBK和UTF-8的区别</h2>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在<span style="color: black;">运用</span>PHP编写的Web程序中,GBK和UTF-8是两种<span style="color: black;">平常</span>的字符编码方式,它们之间有以下区别和优缺点:</p>
    <h3 style="color: black; text-align: left; margin-bottom: 10px;">1. 编码范围:</h3>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">GBK:GBK是中国国家标准的字符集编码,<span style="color: black;">包括</span>简体中文、繁体中文和<span style="color: black;">有些</span>日韩字符,总计<span style="color: black;">包括</span>21003个字符。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">UTF-8:UTF-8是Unicode的一种实现方式,涵盖了全世界几乎所有国家需要用到的字符,<span style="color: black;">能够</span><span style="color: black;">暗示</span>世界上几乎所有的文字。</p>
    <h3 style="color: black; text-align: left; margin-bottom: 10px;">2. 兼容性:</h3>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">GBK:GBK在处理中文文本方面表现良好,但在处理其他语言的文本时可能会<span style="color: black;">显现</span>乱码问题。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">UTF-8:UTF-8<span style="color: black;">拥有</span>更广泛的兼容性,几乎<span style="color: black;">能够</span>处理所有语言的文本,适合国际化项目。</p>
    <h3 style="color: black; text-align: left; margin-bottom: 10px;">3. 存储空间:</h3>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">GBK:GBK编码下,一个中文字符占用2个字节的存储空间,适用于中文网站<span style="color: black;">或</span>只<span style="color: black;">触及</span>中文内容的项目。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">UTF-8:UTF-8编码下,一个中文字符占用3个字节的存储空间,相比GBK更占用存储空间。但由于UTF-8的兼容性好,适用于需要处理多语言的项目。</p>
    <h3 style="color: black; text-align: left; margin-bottom: 10px;">4. URL编码:</h3>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">GBK:GBK编码在URL编码时需要先转为UTF-8,再进行URL编码。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">UTF-8:UTF-8编码在URL编码时不需要做任何转换,相对方便。</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">GBK适合中文网站<span style="color: black;">或</span>纯中文项目,存储空间相对节省;而UTF-8适合需要处理多语言文本的国际化项目,<span style="color: black;">拥有</span>更广泛的兼容性。<span style="color: black;">然则</span>在做网站<span style="color: black;">选取</span>编码的时候,你只需要<span style="color: black;">按照</span>自己的项目<span style="color: black;">需要</span>和特点进行<span style="color: black;">恰当</span><span style="color: black;">选取</span><span style="color: black;">就可</span>。既然不管GBK和UTF-8编码格式都不影响网站的正常<span style="color: black;">运用</span>,<span style="color: black;">那样</span>本文为啥还要介绍PHP<span style="color: black;">怎样</span>把GBK以及其他编码格式的文件转换成UTF-8呢?理由有两点:一,兼容性;二,程序文件的编码统一性,<span style="color: black;">由于</span><span style="color: black;">倘若</span>你网站<span style="color: black;">同期</span>有GBK和UTF-8的编码文件,<span style="color: black;">那样</span>大概率会<span style="color: black;">显现</span>中文字符乱码的现象。以前用Discuz做网站的时候,经常<span style="color: black;">发掘</span>某些Discuz插件要么只支持UTF-8要么支持GBK,安装后就<span style="color: black;">显现</span>乱码,<span style="color: black;">不堪</span>其烦。<span style="color: black;">那样</span>我用PHP来写一个编码转换工具不就<span style="color: black;">能够</span><span style="color: black;">处理</span>类似问题了吗?</p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><img src="https://mmbiz.qpic.cn/sz_mmbiz_png/fm7RnX9X5QTfNHIVLwZ5KN2G9sx0YwK9KE5vP8jic87FY1qCG6rz4HrsVqY9QR3iaLsa4VodA87Zgwm5u7oFwReg/640?wx_fmt=png&amp;from=appmsg&amp;tp=webp&amp;wxfrom=5&amp;wx_lazy=1&amp;wx_co=1" style="width: 50%; margin-bottom: 20px;"></p>
    <h2 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">2、</span>PHP变量编码转换</h2>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">那样</span>PHP如何进行编码转换呢?在PHP中,<span style="color: black;">能够</span><span style="color: black;">运用</span>内置函数mb_convert_encoding()来进行编码转换。该函数<span style="color: black;">能够</span>将字符串从一个字符编码转换为另一个字符编码。例如,<span style="color: black;">倘若</span>你想将一个UTF-8编码的字符串转换为GBK编码,<span style="color: black;">能够</span><span style="color: black;">根据</span>以下<span style="color: black;">过程</span>进行:</p><span style="color: black;">// 将UTF-8编码的字符串转换为GBK编码</span><span style="color: black;">$utf8_string</span> <span style="color: black;">=</span> <span style="color: black;">需要转换的UTF-8字符串</span><span style="color: black;">;</span><span style="color: black;">$gbk_string</span> <span style="color: black;">=</span> <span style="color: black;">mb_convert_encoding</span><span style="color: black;">(</span><span style="color: black;">$utf8_string</span><span style="color: black;">,</span> <span style="color: black;">GBK</span><span style="color: black;">,</span> <span style="color: black;">UTF-8</span><span style="color: black;">)</span><span style="color: black;">;</span>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">在上面的示例中,mb_convert_encoding()函数的<span style="color: black;">第1</span>个参数是待转换的字符串,第二个参数是<span style="color: black;">目的</span>编码,第三个参数是原始编码。<span style="color: black;">经过</span>这种方式,你<span style="color: black;">能够</span>在PHP中方便地进行编码转换。</p>
    <h2 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">3、</span>PHP文件编码转换</h2>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">当然案例中只是演示了对字符串的转换,<span style="color: black;">然则</span><span style="color: black;">咱们</span>的目的是对文件的转换,<span style="color: black;">那样</span><span style="color: black;">咱们</span>读取文件内容,再对</span>文件<span style="color: black;">内容进行转换不就<span style="color: black;">能够</span>了吗?</span></p><span style="color: black;">// 读取test.txt文件内容</span><span style="color: black;">$content</span> <span style="color: black;">=</span> <span style="color: black;">file_get_contents</span><span style="color: black;">(</span><span style="color: black;">test.txt</span><span style="color: black;">)</span><span style="color: black;">;</span><span style="color: black;">// 将文件内容转换为UTF-8编码</span><span style="color: black;">$content_utf8</span> <span style="color: black;">=</span> <span style="color: black;">mb_convert_encoding</span><span style="color: black;">(</span><span style="color: black;">$content</span><span style="color: black;">,</span> <span style="color: black;">UTF-8</span><span style="color: black;">,</span> <span style="color: black;">mb_detect_encoding</span><span style="color: black;">(</span><span style="color: black;">$content</span><span style="color: black;">)</span><span style="color: black;">)</span><span style="color: black;">;</span>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">该代码<span style="color: black;">运用</span>file_get_contents()读取test.txt文件,并将内容转换成UTF-8的编码。mb_convert_encoding()的第三个参数是原始编码,<span style="color: black;">这儿</span><span style="color: black;">运用</span>了mb_detect_encoding()检测原始文件的编码格式,当然<span style="color: black;">亦</span><span style="color: black;">能够</span>替换成auto,在<span style="color: black;">晓得</span>原始文件的编码格式的<span style="color: black;">状况</span>下,<span style="color: black;">咱们</span>还<span style="color: black;">能够</span>指定原始文件编码,<span style="color: black;">例如</span>GBK。</p>
    <h2 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">4、</span>PHP批量文件编码转换</h2>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;">既然<span style="color: black;">咱们</span><span style="color: black;">已然</span><span style="color: black;">处理</span>把文件转换成UTF-8的文件,<span style="color: black;">那样</span>我<span style="color: black;">怎样</span>来完成批量的工作呢?一个程序<span style="color: black;">常常</span>有几十上百个文件,<span style="color: black;">倘若</span>一个个来处理,这效率岂不是太低了。下面<span style="color: black;">咱们</span>来写一个简易的批量编码<span style="color: black;">转换工具,</span>案例代码:</p><span style="color: black;">&lt;?php</span><span style="color:
