How to convert file encoding in php
php转换文件编码的方法:使用函数【str_replace】转换文件编码到新文件夹,代码为【$newPath = str_replace(THIS_PATH, THIS_PATH . DS . Cover, $v)】。
php转换文件编码的方法:
代码
<?php define('THIS_FILE', __FILE__); // 此文件路径,请勿修改,将跳过此文件 define('THIS_PATH', dirname(THIS_FILE)); // 当前路径,可修改 define('Cover', 'new'); // 是否直接覆盖本文件(改为 true 不加单引号,危险),建议写入其他地址(相对于当前路径) define('DS', DIRECTORY_SEPARATOR); // Linux改为'/',Windows为'\\' define('ICONV', 'UTF-8'); // 最终转换编码格式 function eachFile($path, $files = []) { if (Cover !== true && $path == THIS_PATH . DS . Cover) { return $files; } if (preg_match("/[\x7f-\xff]/", $path)) { $path = iconv('UTF-8', 'GBK', $path); } if (is_file($path)) { $files[] = $path; return $files; } $list = scandir($path); foreach ($list as $k => $v) { if ($v !== '.' && $v !== '..') { $p = $path . DS . $v; // 路径转码GBK if (preg_match("/[\x7f-\xff]/", $p)) { $p = iconv('UTF-8', 'GBK', $p); } if (is_dir($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($ext, ['txt', 'php', 'css', 'js', 'htm', 'html'])) { if ($v == THIS_FILE) continue; // 获取内容并转码 $contents_before = file_get_contents($v); $oldIconv = mb_detect_encoding($contents_before, array('ASCII', 'GB2312', 'GBK', 'UTF-8', 'BIG5')); $contents_after = iconv($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>"; } } }
