How to convert file encoding in php

php转换文件编码的方法:

代码

<?php
define(&#39;THIS_FILE&#39;, __FILE__); // 此文件路径,请勿修改,将跳过此文件
define(&#39;THIS_PATH&#39;, dirname(THIS_FILE)); // 当前路径,可修改
define(&#39;Cover&#39;, &#39;new&#39;); // 是否直接覆盖本文件(改为 true 不加单引号,危险),建议写入其他地址(相对于当前路径)
define(&#39;DS&#39;, DIRECTORY_SEPARATOR); // Linux改为&#39;/&#39;,Windows为&#39;\\&#39;
define(&#39;ICONV&#39;, &#39;UTF-8&#39;); // 最终转换编码格式
function eachFile($path, $files = [])
{
    if (Cover !== true && $path == THIS_PATH . DS . Cover) {
        return $files;
    }
    if (preg_match("/[\x7f-\xff]/", $path)) {
        $path = iconv(&#39;UTF-8&#39;, &#39;GBK&#39;, $path);
    }
    if (is_file($path)) {
        $files[] = $path;
        return $files;
    }
    $list = scandir($path);
    foreach ($list as $k => $v) {
        if ($v !== &#39;.&#39; && $v !== &#39;..&#39;) {
            $p = $path . DS . $v;
            // 路径转码GBK
            if (preg_match("/[\x7f-\xff]/", $p)) {
                $p = iconv(&#39;UTF-8&#39;, &#39;GBK&#39;, $p);
            }
            if (is_dir($p)) {
                $files = eachFile($p, $files);
            } else {
                $files[] = $p;
            }
        }
    }
    return $files;
}
$files = eachFile(THIS_PATH);
foreach ($files as $k => $v) {
    $ext = pathinfo($v, PATHINFO_EXTENSION);
    if (in_array($ext, [&#39;txt&#39;, &#39;php&#39;, &#39;css&#39;, &#39;js&#39;, &#39;htm&#39;, &#39;html&#39;])) {
        if ($v == THIS_FILE) continue;
        // 获取内容并转码
        $contents_before = file_get_contents($v);
        $oldIconv = mb_detect_encoding($contents_before, array(&#39;ASCII&#39;, &#39;GB2312&#39;, &#39;GBK&#39;, &#39;UTF-8&#39;, &#39;BIG5&#39;));
        $contents_after = iconv($oldIconv, ICONV, $contents_before);
        if (Cover !== true) {
            // 判断新文件夹是否存在
            $newPath = str_replace(THIS_PATH, THIS_PATH . DS . Cover, $v);
            if (!file_exists(dirname($newPath))) {
                mkdir(dirname($newPath), 0755, true);
            }
            // 覆盖写入文件(不存在自动创建)
            file_put_contents($newPath, $contents_after);
        } else {
            file_put_contents($v, $contents_after);
        }
        // 输出
        echo "{$v} 已转换<hr>";
    } else {
        $newPath = str_replace(THIS_PATH, THIS_PATH . DS . Cover, $v);
        if (Cover !== true && !file_exists($newPath)) {
            if (!file_exists(dirname($newPath))) {
                mkdir(dirname($newPath), 0755, true);
            }
            copy($v, $newPath);
            echo "{$v} 复制文件到新路径 {$newPath}<hr>";
        }
    }
}
Copy after login

功能

  • 自定义文件夹

  • 跳过本文件(同一文件夹)及新文件夹(多次转码)

  • 文件格式限制

  • 转换文件编码到新文件夹(推荐)或本文件

  • 复制无需转码文件到新文件夹

注意

  • 暂未在Linux上测试

  • 只能转码文本文件
