How to loop through file and delete lines starting with "#"

I need to loop through a file and delete all lines starting with #
I was thinking of some regex like: ^#.*\n$ will that work?

 

u will need to use preg match function .

- read a file
- declare an array
- insert each line in the array
- pregmatch function to see if the line begin with #
- delete the line

now implement it

 

sorry, never used pregmatch, nor writing lines into an array
info for the n00b thanks a bunch

 

preg match with example : http://ca.php.net/preg-match

reading line and inserting them into an array :

<?php
if (is_readable("file.txt")) {
  $filecontent = file("file.txt");
  echo "<ul>\n";
  for ($i=0; $i < sizeof($filecontent); $i++) {
    echo "  <li>", rtrim($filecontent[$i]), "</li>\n"; // instead of echoying , apply a method , like test (if (preg match ..) xxx , else ... 
  }
  echo "</ul>\n";
} else {
  echo "cannot read file ...\n";
}
?>

PHP:

 

ok, I repped you... will try to get this working.
