Hi Bob,
How do you deal with "500 or more "X"s with no spaces"?
================================
Hi Mike,
My last regex about this wouldn't have worked.
I thought I'd reproduce it just as an exercise. It's really overkill and took
it off, but it does seem to work. I couldn't ban the IP (must have been from a
group of lads as they plaqued me for ages) but they tired after I put this on
:-)
<?php
//just a test program
if ($_POST['submit'] == "Submit") {
$result = array();
//used own array instead of looped thro ASCII code. Note: dot needs escaping
in array
$char =
array('-','a','b','c','d','e','f','g','h','i','j','k','l','m','n','o','p','q','r','s','t','u','v','w','x','y','z','0','1','2','3','4','5','6','7','8','9',"'",'"',',','\.','
');
//kill everything accept these
$raw = preg_replace('/[^-A-Za-z0-9\'\"\,\.\r\n ]/', '', $_POST['raw']);
$raw = nl2br($raw);
$raw = explode(' ', $raw);
foreach ($raw as $word) {
foreach ($char as $x) {
$word = preg_replace("/($x){3,}/i", '$1$1', $word);
}
$result[] = $word;
}
$result = implode($result, ' ');
echo $result;
}
?>
<form action="<?php echo $_SERVER['PHP_SELF']; ?>" method="post">
<textarea name="raw" cols="50" rows="5"></textarea>
<input type="submit" name="submit" value="Submit" />
</form>
Regards, Bob E.
