What are some best practices for efficiently extracting text after a delimiter in PHP?

When extracting text after a delimiter in PHP, one efficient way is to use the explode function to split the string into an array based on the delimiter, and then access the desired text using array indexing. Another approach is to use the substr and strpos functions to find the position of the delimiter and extract the text after it. Regular expressions can also be used for more complex delimiter patterns. 

// Using explode function
$text = "Hello, World!";
$delimiter = ",";
$parts = explode($delimiter, $text);
$extracted_text = $parts[1];
echo $extracted_text;

// Using substr and strpos functions
$text = "Hello, World!";
$delimiter = ",";
$position = strpos($text, $delimiter) + 1;
$extracted_text = substr($text, $position);
echo $extracted_text;

// Using regular expressions
$text = "Hello, World!";
$delimiter = ",";
$pattern = "/$delimiter(.*)/";
preg_match($pattern, $text, $matches);
$extracted_text = $matches[1];
echo $extracted_text;
