What is the best way to extract specific content from a string in PHP?

When extracting specific content from a string in PHP, you can use functions like `strpos`, `substr`, `preg_match`, or `explode` depending on the complexity of the extraction needed. These functions allow you to search for specific patterns or substrings within a string and extract the desired content. 

// Example: Extracting a specific substring from a string
$string = "Hello, my name is John Doe. I am 30 years old.";
$start = strpos($string, "name is ") + strlen("name is ");
$end = strpos($string, ".", $start);
$extracted = substr($string, $start, $end - $start);
echo $extracted; // Output: John Doe
