?>
description searches in a string for a collection of stings from an array, returns true or false
you can also search for more than one words in combination
mstristr is case-insensitive
syntax <?php
bool = mstristr(string haystack, array needles);
?>
explanation so we search for a list of badwords in a text
<?php
    $badwords[0] = "viagra";
    $badwords[1] = "cialis";
    $badwords[2] = "casino";
    $badwords[3] = "porn";

    $text = "Hi Your website is sooo fantastic! Please Try my viagra!";
    
    $bool = mstristr($text,$badwords);
?>

in that case $bool is true.

ok, now we want all badwords as combination, so a badword has to occure with a link
<?php
    $badwords[0] = array("http:","viagra");
    $badwords[1] = array("http:","cialis");
    $badwords[2] = array("http:","casino");
    $badwords[3] = array("http:","porn");

    $text = "Hi Your website is sooo fantastic! Please Try my viagra or cialis!";
    
    $bool = mstristr($text,$badwords);
?>

in that case $bool is false, cause none of the combinations was found.
