Remember that this method is NOT search engine friendly, since the bot will have a dificult time reading your text. Only humans can read.
| <?php
// main function, will call the replacews() function
function ghostText($data){
return preg_replace_callback('{((\s)+?)}i', "replacews", $data);
}
function replacews($xxx){
$c = chr(mt_rand(62,155));
return "<span style='color:#fff'>$c</span>";
}
?> | |
And the usage is still quite simple:
| <?php
$data = "Quick brown fox jumps over the lazy dog!";
echo ghostText($data);
?> | |
Then any whitespaces will be replaced with random character in white color. |
