How can developers optimize PHP code for efficient text processing and manipulation?

Developers can optimize PHP code for efficient text processing and manipulation by using built-in functions like `strpos`, `str_replace`, `substr`, and `preg_match` instead of custom functions. Additionally, they can minimize the use of regular expressions and loops to improve performance. 

// Example of optimized PHP code for text processing and manipulation
$text = "Hello, World!";
$position = strpos($text, ",");
$newText = str_replace("Hello", "Hi", $text);
$substring = substr($text, 0, 5);

echo $position . "\n"; // Output: 5
echo $newText . "\n"; // Output: Hi, World!
echo $substring; // Output: Hello
