PHP Traversal directory/file in two ways

1. Use $obj = Dir ($dir) to return the directory object $obj, and then use its $obj->read () method to traverse;

1<?PHP2 /**3 * Created by Phpstorm.4 * User:zhang He5 * DATE:2015/6/86 * time:12:217  */8 functionTraversedir ($filedir ) {9     //Open DirectoryTen     $dir= @dir($filedir); One     //list files in a directory A      while(($file=$dir->read ())!==false){ -         if(Is_dir($filedir." /".$file) and ($file!=".") and ($file!="..")){ -             //recursive traversal of subdirectories theTraversedir ($filedir." /".$file); -}Else { -             //output file full path -             Echo"FileName:".$filedir." /".$file. "<br/>"; +         } -     } +     $dir-close (); A } at //testing: Traversing the current directory -Traversedir ("."); -?>

2, First Use $obj = Opendir ($dir) to get the object $obj, and then use Readdir ($obj) to traverse the directory

1<?PHP2 /**3 * Created by Phpstorm.4 * User:zhang He5 * DATE:2015/6/86 * time:12:217  */8 functionTraversedir ($dir){9     if(Is_dir($dir)){Ten         if($obj=Opendir($dir)){ One              while(($file=Readdir($obj)) !==false){ A                 if((Is_dir($dir." /".$file)) and$file! = "." and$file!=".."){ -                     Echo"<b><font color= ' red ' > FileName:</font></b>",$file, "<br>; -Traversedir ($dir." /".$file." /"); the}Else{ -                     if($file! = "." and$file!=".."){ -                         Echo $file." <br> "; -                     } +                 } -             } +             Closedir($obj); A         } at     } - } - //testing: Traversing the current directory -Traversedir ("."); -?>
