What potential issues can arise when manipulating strings in PHP, such as splitting and rejoining them?

One potential issue when manipulating strings in PHP, such as splitting and rejoining them, is the possibility of encountering encoding problems. To solve this, it's important to ensure that the encoding of the strings is consistent throughout the manipulation process. You can use functions like mb_internal_encoding() and mb_convert_encoding() to handle different encodings effectively. 

// Set internal encoding to UTF-8
mb_internal_encoding('UTF-8');

// Convert string to UTF-8 before splitting
$string = mb_convert_encoding($string, 'UTF-8');

// Split the string
$parts = explode(' ', $string);

// Join the parts back together
$newString = implode(' ', $parts);
