Solution 1
use
for an array use the following function
function substr_count_array( $haystack, $needle ) {
$count = 0;
foreach ($needle as $substring) {
$count += substr_count( $haystack, $substring);
}
return $count;
}
Solution 2
You can use this code:
$bad_words = array("yo","hi");
$sentence = "yo you your";
// break your sentence into words first
preg_match_all('/\w+/', $sentence, $m);
echo ( array_diff ( $m[0], $bad_words ) === $m[0] ) ? "no bad words found\n" :
"bad words found\n";
Solution 3
// returns false or true
function multiStringTester($feed , $arrayTest)
{
$validator = false;
for ($i = 0; $i < count($arrayTest); $i++)
{
if (stringTester($feed, $arrayTest[$i]) === false )
{
continue;
} else
{
$validator = true;
}
}
return $validator;
}

I have looked around the internet for something that will do this but it will only work with one word.
I am trying to build a script that will detect a bad username for my site, the bad username will be detected if the username contains any of the words in an array.
Here's the code I made, but failed to work.
$bad_words = array("yo","hi"); $sentence = "yo"; if (strpos($bad_words,$sentence)==false) { echo "success"; }
If anybody could help me, I would appreciate it.
