How do i open a file, find something in that file, and replace it?

 

I tried str_replace($old, $new, $data)

 

data is the file i want to replace in and it's correct. i'm using fread to read the file.

 

$old and $new are outputting correctly, if i change them to words, the str_replace works fine?

Do you need quotes around $new and $old?

nope, shouldn't need them, i tried putting them in but it didn't make a difference.

 

This is what i have so far, i'm still learning so bare with me, and any alterations explain rather than just putting them in there

 

$new = $_POST['update_value']; 
$old = $_POST['original_html']; 
$myfile = "index.html";

$fh = fopen($myfile, 'r') or die('can\'t open file');
$data = fread($fh, filesize($myfile));
$output = str_replace($old, $new, $data);
// $output .= $old;
// $output .= $new;
// $output .= $data;


$fht = fopen($myfile, 'w') or die('can\'t open file');
fwrite($fht, $output);
fclose($fht);

Whatever you wanna know

 

But hey, what can i say, am a swinger (jokes!)

 

I know i'm TERRIBLE with literacy, and you've already pointed out the bear thing with me, i have taken note and i do get it right sometimes, but sometimes i just forget to pay attention to what i'm writing. Bad habbits an' all.

 

I'm sorry, forgive me?

ROFL

Have you considered file_get_contents()?

 

$out = file_get_contents("file_to_search.html");
$out = str_replace($old, $new, $out);

echo $out;

 

then if you want to save, just fwrite() $out.

i tried, it didn't work.

 

It just truncated the page and wrote "array", although that's probably mybad. I didn't have time to fiddle with it more, i'll try again when i get some time.
