I have developed a script to filter swear words by reading a text file
that contains swear words and replace it with **** as follows...
test.txt:
bad1
bad2
bad3
anotherbad2
filter.php:
<?php
$textarea = "bad1 anotherbad2 bad3";
$filename = "test.txt";
$fp = fopen($filename, "r") or die("File not there");
while (!feof($fp)) {
$line = fgets($fp, 1024);
$wordlen = strlen(trim($line));
$count = 1;
$newword = "";
while ($count <= $wordlen) {
$newword .= "*";
$count++;
}
echo "Line = $line<br>";
echo "New Line = $newword<br>";
$textarea = preg_replace('/\b'.$line.'\b/i', $newword, $textarea);
}
echo $textarea;
?>
Below is the output I get....
Line = bad1
New Line = ****
Line = bad2
New Line = ****
Line = bad3
New Line = ****
Line = anotherbad2
New Line = ***********
bad1 *********** bad3
For some reason it only does the replace on the last work in the list
within test.txt, in this case "anotherbad2".
I update $textarea after every line in the while loop so I don't
understand.
Can anyone help?
Thanks
Mike
