Can you remove stuff from .htaccess using php?

From what I've checked or found is a lot of people are having issues with that.

I supposed you could create a list of the contents using PHP, then edit what you want on the list, then rewrite it. Best I could think of for now.

Not the correct answer you need, but some input!

Yeh I did a bit searching myself on goggle first before posting this thread but did not find anything. Seems a bit weird you can write to a file using php but you cant remove.

I remember Prestashop did some rewriting/editing in .htaccess when enabling/changing seo urls or other settings like compression and stuff, so it's possible.
You can do something like getting the file's content > put it in a variable > search and replace/remove what you need > rewrite the file.

Here, I use this function to write .php files in a script that helps translate/create locale files. Not tested under *nix.
[syntaxhighlighter brush=php,first-line=1,highlight=0,collapse=false,html-script=false]function create_file($ofile, $content) {
$oFile = fopen($ofile, 'w';
if (flock($oFile, LOCK_EX)) {
fwrite($oFile, $content);
flock($oFile, LOCK_UN);
} else {
echo "<div class='admin-message'>Ooops! Something went wrong while atempting to write the file.<br />Please try again.</div>";
}
//Done writing, close file
fclose($oFile);
}[/syntaxhighlighter]
I could help with regex if you give more details about what are trying to achieve.

I'll be using fwrite or similar to write the ip to .htaccess but what can I use to then remove it from .htaccess?

Read, remove the bad string, write.

Example code please?

[syntaxhighlighter brush=php,first-line=1,highlight=0,collapse=false,html-script=false]$input = file_get_contents("file.php";
$output = preg_replace("#what_to_find#i", "replacement", $input);
create_file("file.php", $output);[/syntaxhighlighter]

Ah maybe your onto something there. Let me try something out and I'll see if it works for what I'm doing can...



do it like that coz it will be a specific thing it needs to remove when submit on $_POST

That should do. It might happen that you are left with blank new lines, to get rid of them too try

OK thanks...

?That wont replace my file with a new one will it?

That's basically what will do. Don't worry the content will still be there, assuming that you did the replacement/addition/removal of a particular line properly.

Yep that works. Thanks for your help.
