How can PHP developers effectively utilize the php.net documentation and forum search function to find solutions to common issues like extracting URLs?

To extract URLs from a string in PHP, you can use regular expressions to search for patterns that match URLs. One common way to achieve this is by using the preg_match_all function with a regular expression that captures URLs. 

$string = "Check out this website: https://www.example.com and also visit http://www.anotherexample.com";
preg_match_all('/https?:\/\/\S+/', $string, $matches);
$urls = $matches[0];

foreach ($urls as $url) {
    echo $url . "\n";
}
