/**

 //Write file
 $file_path="text.txt";
 if(!file_exists($file_path)){
 echo "The file does not exist";
 exit();
 }
 //"a+" Append "w+" to the end of the file and rewrite
 $fp=fopen($file_path,"w+ ");
 $con="rnHello";
 for($i=0;$i<10;$i++){
 fwrite($fp,$con);}
 fclose($fp);
?>

Method 2, write the file through the file_put_contents function

 //Second way to write files
 $file_path="text.txt";
 $content="hello,worldrn";
  //The default for writing a string to a file is [FILE_USE_INCLUDE_PATH] "w+" re-write
 file_put_contents($file_path,$content,FILE_APPEND);
 echo "OK" ;
?>
