" <br/> "; }else{  echo" file cannot be opened "; } }else{  echo" does not have this file; }  fclose ($FP);    //******************* The second way to read ***************************    code is as follows: Header ("content-type:text/ Html;charset=utf-8 "); //file path   $file _path=" Text.txt ";  $conn =file_get_contents ($file _path);  $ Conn=str_replace ("RN", "<br/>", file_get_contents ($file _path));  echo $conn;  fclose ($fp);   //****************** The third way to read, loop read *****************    code as follows: Header ("Content-type:text/html;charset =utf-8 "); File path   $file _path= "text.txt"; //Determine if file exists   if (file_exists ($file _path)) { //Determine if file can open   if ( $FP =fopen ($file _path, "A +")) {  $buffer =1024; //edge reading to determine whether the end of the file is at   $STR = "";  while (!feof ($fp)) {   $STR. =fread ($fp, $buffer); } }else{  echo "file cannot open"; } }else{  echo "does not have this file"; nbsp } //Replacement characters   $STR =str_replace ("RN", "<br>", $str);  echo $str;  fclose ($fp);  Functions that read the INI configuration file:  $arr =parse_ini_file ("Config.ini"); //Returns the array   echo $arr [' Host '].
