$MENSAGEM = filter_var($text, FILTER_SANITIZE_STRING, FILTER_FLAG_ENCODE_AMP);
How can I avoid comments of this type.
pppppp........ ou udaisoduasiudaosidua.... repetindo...
What breaks the whole site?
I know I can do this by adjusting with css, but I wanted to block this post using php.
My system already has a login, only those who can post are users!
<?php
$str = "sssrrrry";
$v = array("a", "b", "c", "d", "e", "f", "g", "h", "i", "j", "k", "l", "m", "n", "o", "p", "q", "r", "s", "t", "u", "v", "w", "y", "z");
for($i = 0; $i < 25; $i++){
$quant = substr_count($str, $v[$i]);
$cont[] = $quant;
}
rsort($cont);
if($cont[0] > 1){
echo "Houve ". $cont[0] ." duplicações de somente 1 caractere na string";
}
?>
