Searching for a string inside a webpage...

How would I search for a string that is on a external webpage using like egrep and curl or something. I then need it to perform an If else function...If found echo "found" else echo "not found"...

Thanks

try this one.

PHP Code:

---


$content = strip_tags(file_get_contents($URL));

if (strstr($content,$word)) {
   echo 'found';
}
else {
   echo 'not found';
}
