Deleting Specific Line In File?

[RyanJones]

Hi guys,

The following code is suposed to match @delete=(n)@ (Where n is a post number in a shoutbox) and then delete the line n but, the problem is it does not work, ideas anyone?

<?php
if ($Is_Admin){
  if (preg_match("/@delete=(\d)@/", $_POST['Content'], $RowToDelete)){
    $RowToDelete = $RowToDelete[0];
    $FileName = "Shout.txt"; // The file which holds all the data.
    $FileArray = file($FileName); // Open the data file as an array.
    $NumLines = count($FileArray); // Count the elements in the array.
    $FP = fopen($FileName, "w"); // Open the file for writing.
    for($i = 0; $i < $NumLines; $i++){// Overwrite the content except the line to be deleted.
      if($i != ($RowToDelete  - 1)){
        fwrite($FP, $FileArray[$i]);
      }
      fclose($FP); // Close the data file.
    }
  }
}
?>

Presume $Is_Admin is true and $_POST['Content'] is @delete=(A Number)@

Any ideas?

Thanks for the help,

not sure if the rest will dou what you want it to, but are you sure $RowToDelete looks the way you expect?

$RowToDelete = $RowToDelete[0]; 

mixed preg_match ( string pattern, string subject [, array &matches [...]])
If matches is provided, then it is filled with the results of search. $matches[0] will contain the text that matched the full pattern, $matches[1] will have the text that matched the first captured parenthesized subpattern, and so on.

Unfortunatly I have already tried that option 🙁

Any other ideas?
