SPL文件相关应用 – 知识点滴

递归查找指定类型的文件

$it1 = new RecursiveDirectoryIterator($path);
$files = new RecursiveIteratorIterator($it1);
$regexIterator = new RegexIterator($files, '/\.(css|js|html|php|tpl)$/');
foreach ($regexIterator as $fileInfo) {

｝

$it1 = new RecursiveDirectoryIterator($path);

$files = new RecursiveIteratorIterator($it1);

$regexIterator = new RegexIterator($files, '/\.(css|js|html|php|tpl)$/');

foreach ($regexIterator as $fileInfo) {

｝

弄个函数

    protected function getFiles($path, $pattern, $recursion = false){
        if($recursion){
            $it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));
        } else {
            $it = new FilesystemIterator($path);
        }

        return new RegexIterator($it, $pattern);
    }

protected function getFiles($path, $pattern, $recursion = false){

if($recursion){

$it = new RecursiveIteratorIterator(new RecursiveDirectoryIterator($path));

} else {

$it = new FilesystemIterator($path);

}

return new RegexIterator($it, $pattern);

}
