did you check the value *before* writing it to a file?
before trying to solve any problem, you have to know
where to look.... perhaps the problem lies with the file
instead of the regexp.
the following code worked great for me:
<?php
$html='<a
href="link.htm?something=value&flag=982420537&PHPSESSID=2c86b460d360b13c3ef08b8a46b9c
afc">Lnk</a>';
$html = preg_replace('/&flag=(\d{9})&PHPSESSID=(\w{32})/', append_url(), $html );
print $html;
save_url($html);
die("Done");
function append_url() {
return "&new_url=this";
}
function save_url($html) {
if ( !($f = fopen('test.txt', 'w')) ) {
die("Cannot write file");
}
else {
fwrite($f, $html);
fclose($f);
}
return 1;
}
?>
