function help

[sol01]

I built this function to remove words from a string:

function killbadwords ($uglytext)
{
$wordlist = array("is", "are", "the", "and", "or");
$num_elements = count($wordlist);
for ($i = 1; $i < $num_elements; $i++) {
$uglytext = ereg_replace(" $wordlist[$i] "," ",$uglytext);
}

}

The following is my code:

$asdf = "I am a poor boy who needs to eat some worms and fish";

$uglytext = killbadwords("$asdf");

echo "$asdf<br>";

however the function does not work, any ideas?

echo $uglytext;

This should work (and be a bit faster):

<?
function killbadwords ($uglytext)
{
$wordlist = array ('is', 'are', 'the', 'and', 'or');
foreach ($wordlist as $value)
{
$uglytext = str_replace ($value, ' ', $uglytext);
}
return $uglytext;
}

$asdf = 'I am a poor boy who needs to eat some worms and fish';
$asdf = killbadwords ($asdf);
echo $asdf;
?>

Try this to get your function working:

replace your code:
$uglytext = ereg_replace(" $wordlist[$i] "," ",$uglytext);
with
$uglytext = ereg_replace($wordlist[$i]," ",$uglytext);

Also you may want to add in your $wordlist array a double space twice, to get rid of extra white space.

Also you may want to make the words like " or " rather then "or", so that you do not replace letters in words like "word".

Also, if you make the previous change, you may want to add the code:
$uglytext=" ".$uglytext." ";
so that the first and last word are checked for ugly words.
