How can PHP be used to extract a specific section of text based on certain criteria?

To extract a specific section of text based on certain criteria in PHP, you can use regular expressions to search for the desired text pattern and extract the matching section. By using functions like preg_match() or preg_match_all(), you can easily extract the text that meets your criteria. 

// Sample text to search
$text = "This is a sample text with a specific section that needs to be extracted.";

// Define the criteria to search for
$pattern = '/specific section/';

// Use preg_match() to extract the specific section based on the criteria
if (preg_match($pattern, $text, $matches)) {
    echo "Specific section found: " . $matches[0];
} else {
    echo "Specific section not found.";
}
