What are some common methods for parsing strings and extracting specific content, such as image links, in PHP?

When parsing strings in PHP to extract specific content like image links, a common method is to use regular expressions or built-in functions like `strpos` and `substr` to locate and extract the desired content. Regular expressions provide a powerful way to search for patterns within strings, while `strpos` and `substr` allow for more direct extraction based on specific positions within the string. 

// Example code to extract image links from a string using regular expressions
$string = "This is an example string with an image link <img src='https://example.com/image.jpg'>";
preg_match('/<img src=\'(.*?)\'/', $string, $matches);
$imageLink = $matches[1];
echo $imageLink;
