What are best practices for using preg_match_all in PHP to capture specific content?

When using preg_match_all in PHP to capture specific content, it is important to provide a clear and specific regular expression pattern to match the content you want to extract. Additionally, using capturing groups in the regular expression allows you to isolate the specific content you are interested in. Finally, accessing the captured content from the preg_match_all function's result array will allow you to retrieve the desired information. 

$content = "This is a sample text with some numbers like 12345 and 67890.";
$pattern = '/\b\d+\b/';

preg_match_all($pattern, $content, $matches);

foreach ($matches[0] as $match) {
    echo $match . "\n";
}
