http://www.teste.co.uk/bodyboards/p3
www.extremesportstrader.co.uk/buy/water/

and i would like to remove all the instances of "http://www.teste.co.uk"?

i tried the below开发者_C百科 code but it doesn't work :(

$remove=array("teste.co.uk","127.0.0.1","localhost","wikipedia.org","gmail.com","answers.yahoo.com");

foreach ($list[0] as $key=>$clean)
{
    if (in_array($clean,$remove)) 
    {               
        unset($list[0][$key]);
    }

    echo $clean;
    echo '<br>';   
}

According to Sjoerd:

$url = parse_url($clean);
$host = $url['host'];

if (in_array($host,$remove)) 
{               
    unset($list[0][$key]);
}

Use the parse_url() function to analyse the urls.

in_array($clean,$remove) only works when the strings match exactly. So if $remove contains "teste.co.uk" and $clean contains "http://www.teste.co.uk/bodyboards/p3", it returns false.

for($i=0; $i < count($array); $i++)
{
  //checks for full match
  if($array[$i] == $key)
  //use if(strpos($array[$i], $key) !== FALSE) to check for substrings.
  {
    array_splice($array, $i, 1)
    $i--;
  }
}

If you array $list[0] is the list you printed, your problem will be that http://www.teste.co.uk/bodyboards/p1 is not in array("teste.co.uk","127.0.... Only the exact string "teste.co.uk" is.

Thus you need to do this:

$remove=array("teste.co.uk","127.0.0.1","localhost","wikipedia.org","gmail.com","answers.yahoo.com");

foreach ($list[0] as $key=>$url) {
    // We have to test for each badword individually
    foreach ($remove as $bad) {
        // Using this strpos trick, we can test if $bad is a substring of $url
        if (strpos($url, $bad) !== false) {
            unset($list[0][$key]);
            break;
        }
    }
}
