[RESOLVED] Silly problem..

Say i wanted to code my script shorter, like so:

PHP Code:

---

<?php
    $handle = fopen('mytxt.txt', 'r');
    $contents = (@fread($handle,filesize('mytxt.txt')))[B][COLOR=DarkOrange]++[/COLOR][/B];
    fclose($handle);
    $handle = fopen('mytxt.txt','w');
    fwrite($handle,$contents);
    fclose($handle);
    echo $contents;
?>

---

instead of doing $contents++

why does that return a parse error? its the same exact thing i think

A. Why would you have a add a one to the variable?
B. You don't loop when your reading a file, as PHP reads the whole file at once.

The reason it doesn't work i becuase you are trying to incement a constant. It like saying:

1++

Which won't work becuase the value of one is a constant. The ++ operator increments the value by one and assigns it to that variable.

You can however use this, with the same effect:

PHP Code:

---

$contents++ = (@fread($handle,filesize('mytxt.txt'))); 


---

Because you have put ++ at the end of $contents, it will not increment the value until the right part of the expression has been evaluated and asigned to $contents.

That still doesnt work, gives me parse errors also :confused:

PHP Code:

---

<?php
$filename = 'Users.txt';
$handle = fopen($filename,'r+');
$contents++ = (@fread($handle,filesize($filename))); 
fwrite($handle,$contents);
echo $contents;
fclose($handle);
?>

---

php always baffles me at its wonderfully bad way of describing errors

You'll have to do it as two lines. Sorry :blush:

PHP Code:

---

$contents = (@fread($handle,filesize($filename)));
++$contents; 


---
