bove mentioned program,
I'm trying to retrieve value line by line from uploaded file and concatenate the retrieving value with url,
But I got the error message..
Notice: Trying to get property of non-object in
C:\xampp\htdocs\phpprog\upload_file_add.php on line 50...
Where is my mistake with the description...

Answer 1

I guess you need to check that your $jsondata variable is valid before using json_decode. It's probably you're receiving null in $data so it's no longer an object when you try to access its properties.
Use var_dump($data) after json_decode($jsondata) to verify you're receiving what you expect.

Answer 2

you are giving us code that has variables that we don't know where they come from, like your $f_open and $json. You cannot use fgets() without opening the file with fopen().
$f_name = $_FILES["filetoupload"]["name"];
$f_tmp = $_FILES["filetoupload"]["tmp_name"];
$store = "uploads/".$f_name;
if(move_uploaded_file($f_tmp,$store)){
echo "file uploaded successfully";
echo"<br>";
}
$f_open = fopen($store,"r");
$line = fgets($f_open);
echo $line;
$url = "http://maps.googleapis.com/maps/api/geocode/json?address=";
$furl ="$url"."$line";
echo "$furl";
reading a text file which contains reading_files_with_PHP
the above code displays
reading_files_with_PHP
