replacing contents of a text file

navy · #1 08-10-2006, 01:48 PM

Hi

Code:
<html>
<head>
<title>My Title</title>
<meta.................
..........................
</head>

</bod>
Some texts
</body>
</html>

Now I want to replace the lines between <head> and </head>.

I know how to replace a pattern in the text file. But How can I replace the contents between two patterns.

Try this code

define ('DATA_FILE', 'c:\myfile.txt');

if (!file_exists(DATA_FILE))
{
die ('File not found: '.DATA_FILE);
}

$data = file_get_contents(DATA_FILE);
$replacementText = 'HERE GOES THE HEADER';

$data = preg_replace('/<head>(.*)<\/head>/msiU', $replacementText, $data);

$fd = fopen('w+', DATA_FILE);
fwrite($fd, $data);
fclose($fd);
