Hi Reader's,
Welcome to FindNerd, today we are going to discuss what is  the  use of  fgets in PHP ? 

If you want a function that returns a line from an open file and after a specific length(the length that is specified by you) it should stop returning on a new line for that  you can use fgets() function.

syntax of fgets() :

fgets(file,length)

There are two main parameter of fgets() function 

1- file:-this is a required parameter and specifies the file to read
2- length:-this is a optional parameter.

you can see below example
 

<?php

  //here define a file variable and call file.txt page and use fopen()
  $file = fopen("file.txt","r");
  //here call fgets() 
  echo fgets($file);
  //here call fclose() function
  fclose($file);

?>
