How can regular expressions (regex) be effectively used to extract values from custom tags in PHP?

Regular expressions can be effectively used in PHP to extract values from custom tags by defining a pattern that matches the structure of the tags. By using functions like preg_match() or preg_match_all(), you can extract the desired values from the tags and use them in your code. 

// Example code to extract values from custom tags using regular expressions in PHP

// Custom tag pattern
$pattern = '/<custom_tag>(.*?)<\/custom_tag>/';

// Input string containing custom tags
$input = "<custom_tag>Value1</custom_tag> <custom_tag>Value2</custom_tag>";

// Extract values from custom tags
preg_match_all($pattern, $input, $matches);

// Output the extracted values
foreach ($matches[1] as $value) {
    echo "Value: " . $value . "\n";
}
