Updating constants in a file

[allex01]

I have a file that contains all types of constants that looks like this

 

$CFG['admin']['value']['article_value'] = '9';

$CFG['admin']['value']['article_upload_value'] = '10';

$CFG['admin']['value']['game_comment_value'] = '11';

 

I created a form with input fields where a user can input and change the values for article_value, article_upload_value, game_comment_value. My question is , how can i make those values replace the current values in the constant file when the submit button is hit. You don't have to work with my current scheme. A simple example on how to update constants in a file would be helpfull.

They are not constants, but simple array values. As for writting to a file, take a look at fwrite().

Yes you're write. How can i write to the array values using a form with input fields. I dont' get how to use fwrite to replace the value only.

Do i still need to use fwrite()

 

If you want to actually overwrite the values in the file.

 

If you just want them temporarley overiden you would use something like....

 

<?php

  if (isset($_POST['submit'])) {
    $CFG['admin']['value']['article_value'] = $_POST['admin_value_article_value'];
    $CFG['admin']['value']['article_upload_value'] = $_POST['admin_value_article_upload_value'];
    $CFG['admin']['value']['game_comment_value'] = $_POST['admin_value_game_comment_value'];
  }

?>

Thank you Thorpe. I was looking for a permanent overwrite and not temporary.

On further support on this would be appreciated. I just need guidance in the right direction.

Did you take a look at fwrite()?

[allex01]

Sure, i did. fwrite() writes to a file but my question was how to make it write to a specific array value in the file mentioned above

I'm assuming the general funcitonality of fwrite only writes at the end of a text file by default correct?..
