how to cut blocks of strings from a text file? 1

[silkk]

Hi guys,

does somebody know some simple script how to cut blocks of strings between matchihg words in a text file?

I have this:

$file = ("path to the file")
$word1 = "HEAD" ;
$word2 = "FOOT" ;

$handle = fopen($file, "r");
$contents = fread($handle, filesize($file));
fclose($handle);
$between=substr($contents, strpos($contents, $word1), strpos($contents, $word2) - strpos($contents, $word1));

echo $between ;

I have in the text more than 10 blocks startin and ending with these words and my task is to cut some of them and to write the result into a new file.

Any suggestions?
Help will be appreciated.

Cheers,
M.

$word1 = "HEAD" ;
$word2 = "FOOT" ; 
$pattern = '/'.$word1.'(.*?)'.$word2.'/imsx';
preg_match_all($pattern, file_get_contents($file), $matches);
echo "<pre>".print_r($matches,true).'</pre>';
