finding a word in a page?

if i wget a page, is there any function i can use to find words located in that page? it's an html page

 

if(stristr($page, '<a href="http://www.enterstation.com"') === TRUE)
{

echo 'link found';
}
else
{
echo 'no link found';
}

 

if you mean wget from the command line then you can use this code ( after you have downloaded the page)
cat dowloadedpage.html | grep word

 

assuming you are talking about PHP, use preg_match
