$word = file_get_contents('http://www.pixelmon-server-list.com/list.txt');
$content = file_get_contents('http://www.pixelmon-server-list.com/fleetyfleet.txt');
$found_dimensions = array(); // our array
$word_array = explode(' ', $word); // explode the list
foreach($word_array as $one_word) { // loop over it
    $str = 'DimensionName'.$one_word; // what are we looking for?
    if(strstr($content, $str) !== false) { // look for it!
        echo $one_word; // Just for demonstration purposes
        $found_dimensions[] = $one_word; // add to the array
    }
}

okay i have a list.text and a fleetyfleet.txt both can be viewed here i didn't post them for space sake http://pastebin.com/7hWDUG1b but what i want to do is find the words in list.txt but only add them to array if there prefix is Dimension Name but the special characters make it kinda tough I'm not sure what i should do

Answer 1

I had a similar problem where I needed to remove all non-ascii characters from a file. Here's the regex I used:

s/[^\x00-\x7F]//g

If you're on linux, here's a quick one-liner:

perl -p -i -e "s/[^\x00-\x7F]//g" list.txt

Answer 2

Having to guess a little bit as I can't see the files from behind my firewall. The following code might help you:

<?php
$f1 = explode("\n",file_get_contents("./file1.txt"));
$f2 = file_get_contents("./file2.txt");
$found = array();
foreach($f1 as $x) {
  $str = "/DimensionName.....$x./";
  if (strlen($x)>0) {
    if (preg_match($str, $f2, $matches)) {
      echo $matches[0]."\n";
    }
  }
}
?>

This prints out lines that include a pattern DimensionName followed by 5 "anything" followed by whatever word was read from the first file file1.txt .

If you need this to be further refined, please leave a comment.
