Strings are used everywhere. PHP gives many helpers.
  
  ## Common string functions
  
  ```php
  $text = " Hello World ";
  
  echo strlen($text);
  echo trim($text);
  echo strtoupper($text);
  echo strtolower($text);
  echo str_replace("World", "PHP", $text);
  ```
  
  ## Splitting and joining
  
  ```php
  $words = explode(" ", "I love PHP");
  echo implode("-", $words);
  ```
