What are some best practices for extracting data from text and storing it in variables using PHP?

When extracting data from text using PHP, it is important to use regular expressions to match the desired information and store it in variables. This can be achieved by using functions like preg_match() or preg_match_all() to extract specific patterns from the text. Once the data is extracted, it can be stored in variables for further processing or manipulation. 

$text = "The price of the product is $50.00";
$pattern = '/\$([0-9]+\.[0-9]{2})/';
if (preg_match($pattern, $text, $matches)) {
    $price = $matches[1];
    echo "The price of the product is: $price";
} else {
    echo "Price not found in the text.";
}
