php一个批量转换文件为utf-8的脚本

最近看到 一个 很古老的代码，当时正是gb2312横行的时代，所以，遍地都是gbk编码了。现如今打开，看起来一堆乱码，很不舒服，写了 一个 凑合脚本。

结合shell 跟 php

shell 实际上用的只是find

if [ $# -lt 1 ] then depth=1 else depth=$1 fi

if [ $# -lt 2 ] then name="*" else name="$2" fi

echo "Begin running:"

find . -maxdepth $depth -name "$name" -exec php /Users/qixingyue/sina/bin/cutf_8 .php {} \;

核心php代码：

<?php

if($argc != 2) exit(); $file_name = $argv[1];

if(is_dir($file_name)) return;

$file_name = getcwd() . trim($file_name,".");

if(is_link($file_name)){ echo "Link file: $file_name \n"; return; }

if(!file_exists($file_name)){ echo "None file: $file_name \n"; return; }

if(!is_writeable($file_name)){ echo "Can not write $file_name \n"; return; }

$str = file_get_contents($file_name);

$from_types = array("ASCII", "GBK", "GB2312", "Unicode", "UTF-8"); $this_type = mb_detect_encoding($str, $from_types);

if($this_type == "UTF-8") { echo "Already UTF-8 $file_name \n"; return; }

if($this_type){

echo "$file_name $this_type ========> UTF-8 \n"; $str = mb_convert_encoding($str,"UTF-8",$this_type); file_put_contents($file_name,$str); }
