Random text

  : How would you pick a random piece of text from a text file and store it in a variable?
  :

  This is how I would do it... roughly.
  Let's say that the file looks like this:
  [red]foo
  bar[/red]
  [code]<?php
  $fopened = fopen(file, r); //Open the file... just for reading.
  $string = fread(fopened); //Read it into a string.
  $exploded = explode("/r/n", $string); //Separate it by newline into an array.
  $rand = rand(0, count($exploded)); //Randomize a number between 0 and the number of elements of the array.
  echo "The random word is:/n". $exploded[$rand]; // Echo element $rand of array $exploded
  fclose(file); //Close it.
  ?>
  [/code]
  That's how I would do it. It would either echo "foo" or "bar." Now, if you wanted to separate the words by spaces, not new lines, you would just change the "/r/n" to " ".

  [code]<?php
  $fopened = fopen([blue]file[/blue], r); //Open the file... just for reading.
  $string = fread($fopened); //Read it into a string.
  $exploded = explode("/r/n", $string); //Separate it by newline into an array.
  $rand = rand(0, count($exploded)); //Randomize a number between 0 and the number of elements of the array.
  echo "The random word is:/n". $exploded[$rand]; // Echo element $rand of array $exploded
  fclose(file); //Close it.
  ?>
  [/code]

  Replace the word "file" in blue above with the path of the text file you want to look through.

  i'm getting some big bad errors that i cant fix:
  
  Warning: Wrong parameter count for fread() in /home/public2/public_html/indexframe.php on line 25
  ""
  Warning: fclose(): supplied argument is not a valid stream resource in /home/public2/public_html/indexframe.php on line 29
  
  any ideas?
  
  EDIT: RE-the second error, um, should it be 'fclose($fopened)' rather than the file path?

  the parameters of fopen are (string filename,string mode)
  so it's
  [red]'file'[/red],not file
  [red]'r'[/red],not r
  you can also use array_rand function:[code]echo"The random word is:".$exploded[array_rand($exploded)];[/code]

  yeah. i can also use 'file_get_contents' rather than 'fopen' and then 'fread'
  
  EDIT:
  I also find it better to use '#' insted of next line or space. however (no matter which kind i use) when it shows the last on in the file it adds a space to the end of it, any ideas how to remove this.
