function question

[Sanjib Sinha]

I have two php pages titled index.php and method1.php

code of method1.php is

 

<?php

 

  function s($file = "myfile.html")

  {

 

    return ("$file");

  }

 

 

?>

 

and the code of index.php is

<?php

include ("method1.php");

?>

 

<?php

 

echo s(readfile("myfile.html"));

 

?>

 

The problem is readfile as a function executes fine but at the end a number 347 has come up. Why this happens?

Secondly, can any one tell me whether reading or writing file as function can be done this way, or it is wrong?

I personally would use require instead of include. I use include when it is something that will display data and require when it is only functions. I think they are the same though, except for how they handle errors.

 

I also wouldn't use a file per function. I would make functions.php and put multiple ones in there.

 

The 347 sounds like something to do with the file. What is in myfile.html?

The 347 is from readfile().  readfile() returns an integer representing the number of bytes read in.  I don't understand the point of s() though...

I assumed the s() had more data in it that he took out

Try file_get_contents() instead of readfile(), if you want the contents of the file as a return value.

's' is a function here. I wanted to put html file in variable!

file_get_contents is working perfectly. Number has vanished. thanks.
