How does php query the files in the directory?

PHP Get all the files in the current directory

We sometimes want to get all the file names in the current directory. The following is a method I wrote, please refer to it

// 获取当前文件的上级目录
$con = dirname(__FILE__);
// 扫描$con目录下的所有文件
$filename = scandir($con);
// 定义一个数组接收文件名
$conname = array();
foreach($filename as $k=>$v){
    // 跳过两个特殊目录   continue跳出循环
    if($v=="." || $v==".."){continue;}
    //截取文件名，我只需要文件名不需要后缀;然后存入数组。如果你是需要后缀直接$v即可
    $conname[] = substr($v,0,strpos($v,"."));
}
