How do I grab a certain word from a webpage?

For example

PHP Code:

$handle = fopen("http://www.blah.com", "rb");
$contents = '';
while (!feof($handle)) {
  $contents .= fread($handle, 8192);
}
fclose($handle); 


That will assign the text to $contents, but then how do i find the text I want?

I know its seperated uniquely on the page by a <span class="blah">textiwant</span>

Please help

Thanks

Best to use regular expressions with the preg_match function:
http://us2.php.net/manual/en/function.preg-match.php

[psili]

lookup the function

preg_match()


and write a regular expression to grab your contents. Something like:

$reg="/<.*>?(.*)<.*>/" or something like that.

I haven't tried opening a url with "file_get_contents()" but you could try that instead of your loop, also.

This is what you want:

$contents = str_replace("textiwant", "replacementtext", $contents);

If you are hosting with DreamHost (who disallow file(), file_get_contents() and similar using URL wrappers - so you have to use CURL), use:

PHP Code:

# Begin CURLing
  $ch = curl_init();
  curl_setopt($ch, CURLOPT_URL, "http://www.blah.com");
  # Get content
  curl_setopt($ch, CURLOPT_RETURNTRANSFER, 1);
  $content = curl_exec($ch);

  # Get word from regex string
  preg_match("'<span class=\"blah\">(.*?)</span>'i", $content, $word); 


Otherwise (nearly all other webhosts) use:

PHP Code:

# Get content and load into string
 $content = file_get_contents("http://www.blah.com");

  # Get word from regex string
  preg_match("'<span class=\"blah\">(.*?)</span>'i", $content, $word); 


In both instances the word you are looking for is returned in the variable $word.

Hit me up on ICQ if you have any problems.

I think you misunderstood. He does not know what 'textiwant' is nor does he want to replace it. He wants to find what 'textiwant' is.
