[Resolved] INI Section Delete

Skyld

Any insight on how to go about making a function that deletes a section in an INI file?

I have seen but not played with a set of INI file control functions...

http://pear.php.net/package/Config

however you could simply read in the file into the array with
[man]parse_ini_file/man and then write a loop which would write a string of that array in INI format... just skipping over the section you would like to delete... something as simple as this might do <i left out any sanity checks on $val that you should have>

$filename = 'foo.ini';
$parsed_ini = parse_ini_file($filename,true);
$skip = 'section2';
$output = '';
foreach ( $parsed_ini as $section=>$info ) {
  if ( $section != $skip ) {
    $output += "[$section]\n";
    foreach ( $info as $var=>$val ) {
      $output += "$var=$val\n";
    }
    $output += "\n\n";
  }
}

$file_resource = fopen($filename, 'w');
fwrite($file_resource, $output);
fclose($file_resource);

Hey, thanks mate. I'll give it a try.
Reading it into an array and excluding it, I never thought of that.

Apart from changin += to .= (for text), it worked. Thanks! 🙂

doh... yeah .=
also if you get your code working please post back here so anyone else later reading this thread can share

Heres the code to remove a section from an INI file

<?php
function inidelsection($filename,$section) { 
  $parsed_ini = parse_ini_file($filename, TRUE); 
  $skip = "$section"; 
  $output = ''; 
  foreach ( $parsed_ini as $section=>$info ) { 
    if ( $section != $skip ) { 
      $output .= "[$section]\n"; 
      foreach ( $info as $var=>$val ) { 
        $output .= "$var=$val\n"; 
      } 
      $output .= "\n\n"; 
    }  

  }
  echo "$output";
  $file_resource = fopen($filename, 'w+'); 
  fwrite($file_resource, "$output"); 
  fclose($file_resource);
}
?>
