Array Help

[Plug-in]

I'm trying to make a XML api word blacklist and I'm able to get all the information fine but I'm confusing myself with the array, could you please help, this is my code:

<pre>
<?php
$data = file_get_contents("http://api.jspace.netai.net/blacklist.xml");
$data = simplexml_load_string($data);



//foreach ($data->words->word as $word) {
  //echo (string)$word;
//}

function filter_words($text, $data) {
foreach($data->words->word as $w) {
  $string = str_replace((string)$w, '[!]', strtolower($text));
  return strtoupper($string);
}
}

echo filter_words("Sentence containing unfiltered word - shit.", $data);

?>
</pre>

 

The problem is it returns unfiltered

return exits a function when it is executed, so your loop will only execute once, then exit.

How could I do this alternatively then, I'm quite confused :/

Put return after the loop?

Put return after the loop.

I'm sorry if I look like I want to be spoon fed but I cannot understand why this will not work, the updated code is below and still does not return [!], sorry for the cuss words:

<pre>
<?php
$data = file_get_contents("http://api.jspace.netai.net/blacklist.xml");
$data = simplexml_load_string($data);

function filter_words($text, $data) {
  foreach($data->words->word as $w) {
  $string = str_replace(strtolower((string)$w), '[!]', strtolower($text));
  }
return strtoupper($string);
}

echo filter_words("fuck", $data);

?>
</pre>

[trq]

function filter_words($text, $data) {
  foreach($data->words->word as $w) {
    $text = str_replace(strtolower($w), '[!]', strtolower($text));
  }
  return strtoupper($text);
}

You bute, I'm going to have to read up on (string), obviously my usage of it was incorrect.

Thanks a lot for you help.

That wasn't necessary and also not the issue.
