Bad words replacement

[Jaan]

It's like Show smileys using str_replace() that tutorial. I hope it helps.

PHP Code:

<?php

// Display your form
function form(){

echo "<form action='?act=show' method='post'>"
    ."<textarea name='text' cols='50' rows='10'></textarea><br>"
    ."<input type='submit' value='Show'>"
    ."</form>";
    
}

function show(){

// Request your text
$text = $_REQUEST['text'];

// This will determine things what you want to replace
$bad_words = array("banana", "tomato", "grape");

// This will determine your text replacement
$fix = array("******", "******", "*****");
$content = str_replace($bad_words, $fix, $text);

// Show your text without bad words
echo $content;

}

switch($act){

default;
form();
break;

case "show";
show();
break;

}

?>

have fun
