php gets the file names of all files in a specified folder

<?php function searchDir($path,&$data){
 if(is_dir($path)){
 $dp=dir($path);
 while($file=$dp->read()){
 if($file!='.'&& $file!='..'){
 searchDir($path.'/'.$file,$data);
 }
 }
 $dp->close();
 }
 if(is_file($path)){
 $data[]=$path;
 }
 }
 
function getDir($dir){
 $data=array();
 searchDir($dir,$data);
 return $data;
 }
?>

$list=getDir('image');
 for($i=0;$i<count echo></count>';
 }

for($i=0;$i<count><br><span>In addition, if your file name is Chinese, if the display is garbled, just change the encoding method to gb2312</span><br>
                
                
                <p>
                    The above introduces how PHP can obtain the file names of all files in a specified folder, including the content. I hope it will be helpful to friends who are interested in PHP tutorials. </p>
