Removing Blank Lines From A File

[emcb_php]

Hi,

Im creating a php application that will add/remove/update apache configurations on our raq4's. As each of these servers runs 200+ virtual hosts i want to make sure that there aren't too many blank lines in the apache configuration files.

Betwenn each </VirtualHost> and <VirtualHost> there should only be one blank line, anyone know how i can tell if there are more, and remove them?

Cheers,

p.s: a few people asked me for my version of AvantGo, i have finished it so email me.

$array = file("apache.conf");

$newlinencountered = 0;
$invirtual = 0;
$i = 0;
$j = 0;

while ($i < sizeof($array)) {

 // If we are in virtual set it

if($array[$i] == "<VirtualHost>")
$invirtual = 1;

// if we are exiting virtual reset the
// newline and the invirtual

if($array[$i] == "</VirtualHost>") {
$newlinencountered = 0;
$invirtual = 0;
}// end if

// Ok now... if we are in the virtual
// and we run accross a \n character
// then we enter this case and see
// if we have already got a \n
// if no than just put it in our final
// array if yes than dont put it in or
// "delete" it

if($array[$i] == "\n" && $invirtual == 1){
if($newlinencountered != 1)
$final[$j] = $array[$i];

    $newlinencountered = 1;
 }//end if

else
$final[$j] = $array[$i];

// increment flags
$j++;
$i++;

}// end while

....put array back into the file....

Well this isnt perfect most likely... I hope this is what you want. This should at least give you and idea.

Hope this helps!
