PHP/String/stristr
Detecting whether a string is contained in another string

<?php $password="secretpassword1"; if (strstr($password,"password")){
echo("Passwords cannot contain the word "password".");
} else {
echo ("Password accepted.");
} ?>

Using Substring Alternatives
<source lang="html4strict">
//string strstr ( string haystack, string needle ) //string stristr ( string haystack, string needle ) <?php $url = "www.wbex.ru"; $domain = strstr ($url, "."); echo $domain; ?>
</source>
