Check if string contains a value in array [duplicate]

Question

I am trying to detect whether a string contains at least one URL that is stored in an array.

Here is my array:

$owned_urls = array('website1.com', 'website2.com', 'website3.com'); 

The string is entered by the user and submitted via PHP. On the confirmation page I would like to check if the URL entered is in the array.

I have tried the following:

$string = 'my domain name is website3.com'; if (in_array($string, $owned_urls)) {     echo "Match found";      return true; } else {     echo "Match not found";     return false; } 

No matter what is inputted the return is always "Match not found".

Is this the correct way of doing things?

Answer 1

Try this.

$string = 'my domain name is website3.com'; foreach ($owned_urls as $url) {     //if (strstr($string, $url)) { // mine version     if (strpos($string, $url) !== FALSE) { // Yoshi version         echo "Match found";          return true;     } } echo "Not found!"; return false; 

Use stristr() or stripos() if you want to check case-insensitive.

Answer 2

Try this:

$owned_urls= array('website1.com', 'website2.com', 'website3.com');  $string = 'my domain name is website3.com';  $url_string = end(explode(' ', $string));  if (in_array($url_string,$owned_urls)){     echo "Match found";      return true; } else {     echo "Match not found";     return false; }
