Question

I have a conf file like this: http://pastie.org/768582 and my goal is to get in an array the comments and the key/value of each keys.

array( array(

     comment  => "The PROJECT_NAME tag is a single",

     key  => "PROJECT_NAME",

     value  => "JMK",
),

)

I would know what algoritm do I have to use?

I have already transform the content of the configuration file to an array (line by line) with explode() function.

Now I am trying to get all the comment lines while next line begins with # and the couple key/value but it is here that I have trouble.

If someone have an idea it would be nice. Thx.

Answer 1

This will get you the key/value pairs, but not the comments:

$options = array();

foreach ($line as $l)
{
  $l = trim($l);
  if (strlen($l) && substr($l, 0, 1) !=  # )
  {
    list($key, $value) = explode("=", $l);

    // remove whitespace from the end of the config key
    $key = rtrim($key);

    $options[$key] = $value;
  }
}

Answer 2

here s one way

$content = file_get_contents("file");
$s = preg_split("/#--*/",$content);
$y = preg_split("/

/",end($s));
for($i=0;$i<count($y)-1;$i++){
    if ($y[$i]){
        if (strpos($y[$i],"#")!==FALSE){
            $comment="$y[$i]
";
            $conf=$y[$i+1];
            $cs = array_map(trim,explode("=",$conf));
            $A["comment"]=$comment;
            $A["key"]=$cs[0];
            $A["value"]=$cs[1];
            $TA[]=$A;
        }
    }
}
print_r($TA);

output

Array
(
    [0] => Array
        (
            [comment] => # This tag specifies the encoding used for all characters in the config file
# that follow. The default is UTF-8 which is also the encoding used for all
# text before the first occurrence of this tag. Doxygen uses libiconv (or the
# iconv built into libc) for the transcoding. See
# http://www.gnu.org/software/libiconv for the list of possible encodings.

            [key] => DOXYFILE_ENCODING
            [value] => UTF-8
        )

    [1] => Array
        (
            [comment] => # The PROJECT_NAME tag is a single word (or a sequence of words surrounded
# by quotes) that should identify the project.

            [key] => PROJECT_NAME
            [value] => JMK
        )

    [2] => Array
        (
            [comment] => # The PROJECT_NUMBER tag can be used to enter a project or revision number.
# This could be handy for archiving the generated documentation or
# if some version control system is used.

            [key] => PROJECT_NUMBER
            [value] => 10
        )

)

Answer 3

You could try parse_ini_file(), the format looks compatible. It won t process the comments, though.
