php bad words replacement with stars and output array - php

Question

Following php function is being used to replace bad words with starts but I need one additional parameters that will describe either bad words found or not .
$badwords = array('dog', 'dala', 'bad3', 'ass');
$text = 'This is a dog. . Grass. is good but ass is bad.';
print_r( filterBadwords($text,$badwords));
function filterBadwords($text, array $badwords, $replaceChar = '*') {
$repu = preg_replace_callback(array_map(function($w) { return '/\b' . preg_quote($w, '/') . '\b/i'; }, $badwords),
function($match) use ($replaceChar) {
return str_repeat($replaceChar, strlen($match[0])); },
$text
);
return array('error' =>'Match/No Match', 'text' => $repu );
}// Func
Output if badwords found should be like
Array ( [error] => Match[text] => Bad word dog match. )
If no badwords found then
Array ( [error] => No Match[text] => Bad word match. )

Answer 1

You can use the following:
function filterBadwords($text, array $badwords, $replaceChar = '*') {
//new bool var to see if there was any match
$matched = false;
$repu = preg_replace_callback(array_map(
function($w)
{
return '/\b' . preg_quote($w, '/') . '\b/i';
}, $badwords),
//pass the $matched by reference
function($match) use ($replaceChar, &$matched)
{
//if the $match array is not empty update $matched to true
if(!empty($match))
{
$matched = true;
}
return str_repeat($replaceChar, strlen($match[0]));
}, $text);
//return response based on the bool value of $matched
if($matched)
{
$return = array('error' =>'Match', 'text' => $repu );
}
else
{
$return = array('error' =>'No Match', 'text' => $repu );
}
return $return;
}
This uses reference and if condition to see if there were any matches and then returns response based on that.
Output(if matched):
array (size=2)
'error' => string 'Match' (length=5)
'text' => string 'This is a ***. . Grass. is good but *** is bad.'
Output(if none matched):
array (size=2)
'error' => string 'No Match' (length=8)
'text' => string 'This is a . . Grass. is good but is bad.'

<?php
$badwords = array('dog', 'dala', 'bad3', 'ass');
$text = 'This is a dog. . Grass. is good but ass is bad.';
$res=is_badword($badwords,$text);
echo "<pre>"; print_r($res);
function is_badword($badwords, $text)
{
$res=array('No Error','No Match');
foreach ($badwords as $name) {
if (stripos($text, $name) !== FALSE) {
$res=array($name,'Match');
return $res;
}
}
return $res;
}
?>
Output:
Array
(
[0] => dog
[1] => Match
)
