How to implement file search in PHP? PHP file search program, after entering a path, it will traverse all the files and folders in the directory. Through recursion, you can find each file under the folder, and then match the file name with the entered keywords to find the file you want. Friends in need can refer to the file.

\n"; $GLOBALS['r_file_num']++; } } } } closedir( $handle ); $GLOBALS['dir_num']++; if(strstr($dirName,$GLOBALS['findFile'])){ $loop = explode($GLOBALS['findFile'],$dirName); $countArr = count($loop)-1; if(empty($loop[$countArr])){ echo "  $dirName 
\n"; $GLOBALS['r_dir_num']++; } } }else{ die("没有此路径！"); } } delDirAndFile($_POST['path']); echo "
