What are some best practices for inserting content in between chunks of data in PHP?

When inserting content in between chunks of data in PHP, one best practice is to use the implode() function to join the chunks of data with the content you want to insert. This allows for easy manipulation of the data while maintaining readability and efficiency.

$data = array('chunk1', 'chunk2', 'chunk3');
$content_to_insert = 'inserted content';

// Insert content between chunks of data
$new_data = implode($content_to_insert, $data);

echo $new_data;
