Shorten Code for Inserting Random Invisible Character
This post is related correction to my previous one, inserting invisible random character inbetween words to avoid copy-paste doer.
I wrote a function to insert invisible random character inbetween words, and it used looped str_replace() to seek for the whitespaces. And I realize it’s not good for a very long texts, because the process will slowed down. So here is a new function with call back method, hopefully it will be faster and cooler ^_*
// main function, will call the replacews() function
function ghostText($data){
return preg_replace_callback('{((\s)+?)}i', "replacews", $data);
}
function replacews($xxx){
$c = chr(mt_rand(62,155));
return "$c";
}
?>
And the usage is still quite simple:
$data = "Quick brown fox jumps over the lazy dog!";
echo ghostText($data);
?>
Many thanks to Aryo for simplifying the function ^_*
