Question

I have a string in php example below.

$string = "This is my website example.org check it out!";
if( preg_match( '/\w+\.(?:com|org)/i', $string, $matches)) {
var_dump( $matches[0]);
echo '' . $matches[0] . '';
}

It will echo out

string(11) "example.org" example.org

I need it to only echo out only

example.org

You will need a regular expression to do this. Here is a start:

$string = "This is my website example.org check it out!";
if( preg_match( '/\w+\.(?:com|org)/i', $string, $matches)) {
    // var_dump( $matches[0]);
    // echo '<a href="' . $matches[0] . '">' . $matches[0] . '</a>';
    echo $matches[0];
}

The regex is:

\w+\.(?:com|org)
^   ^^
|   |Match either com or org
|   Match a period
Match one or more word character [A-Za-z0-9_]

This will output:

string(11) "example.org" 

You will need to adapt it to include subdomains and protocols, if necessary.
