What methods can be used to search for specific patterns or strings within a larger text in PHP?

When searching for specific patterns or strings within a larger text in PHP, you can use regular expressions with functions like preg_match() or preg_match_all(). Regular expressions allow you to define a pattern to search for within the text and can be quite powerful for complex searches. You can also use functions like strpos() or stripos() for simple string searches. 

// Using preg_match() to search for a specific pattern in a text
$text = "The quick brown fox jumps over the lazy dog";
$pattern = '/quick/';
if (preg_match($pattern, $text)) {
    echo "Pattern found in the text!";
} else {
    echo "Pattern not found in the text.";
}
