How can PHP developers efficiently extract specific information from a string using predefined patterns?

When extracting specific information from a string using predefined patterns in PHP, developers can use regular expressions. Regular expressions allow for pattern matching within strings, making it easier to extract desired information. By using functions like preg_match() or preg_match_all(), developers can efficiently extract specific data based on predefined patterns. 

<?php

$string = "Hello, my email is example@email.com";
$pattern = '/[a-zA-Z0-9._%+-]+@[a-zA-Z0-9.-]+\.[a-zA-Z]{2,}/';
preg_match($pattern, $string, $matches);

echo "Email found: " . $matches[0];

?>
