Yii语言包词条提取

据说是哥半年前写的一个用户管理程序，而现在老大要求程序能切换语言；将原来的词条用英文添进去之后，发现写语言包的时候一个一个提取比较麻烦，所以就写了个程序提取。(目前还只能提取Yii::t里面只有两个参数的情况)

<?php

$fileinfo = new FilesystemIterator('group'); // 目录

$words = array();
while($fileinfo->valid()) {
    
    if($fileinfo->getExtension() === 'php') {
        $filename = $fileinfo->getFilename();
        $fileobject = $fileinfo->openFile();

        while($fileobject->valid()) {
            if(preg_match_all('/Yii::t\(([\'"])([^\'"]*?)\\1\s*,\s*([\'"])(.*?)\\3\)/', $fileobject->current(), $matches)) {
                foreach($matches[4] as $match) {
                    $words[$match] = isset($words[$match]) ? $words[$match] . '; ' . $filename . ' # ' . $fileobject->key() : '// ' . $filename . ' # ' . $fileobject->key();
                }
            }
            $fileobject->next();
        }
    }

    $fileinfo->next();
}


function save_to_file($content = '') {
    $fileobject = new SplFileObject('user.trans.php', 'w');
    $fileobject->fwrite($content);
}

ob_start('save_to_file');

echo '<?php
/**

return array(

foreach($words as $word => $comment) {
    echo "\t" . $comment . PHP_EOL;
    echo "\t" . '\'' . $word . '\' => \'\',' . PHP_EOL;
}

echo ');
';

ob_end_clean();
