What potential issues can arise from encoding problems in PHP code, as seen in the forum thread?

The potential issues that can arise from encoding problems in PHP code include displaying garbled text, incorrect character rendering, and data corruption. To solve encoding problems, it is important to ensure that the PHP files are saved with the correct encoding (UTF-8 is recommended), and that any input/output operations are properly encoded and decoded using functions like mb_convert_encoding() or utf8_encode()/utf8_decode(). 

// Ensure correct encoding for PHP files
header('Content-Type: text/html; charset=utf-8');
mb_internal_encoding('UTF-8');

// Example of encoding and decoding data
$inputString = "Hello, 你好";
$encodedString = mb_convert_encoding($inputString, 'UTF-8');
$decodedString = mb_convert_encoding($encodedString, 'UTF-8', 'UTF-8');

echo $decodedString; // Output: Hello, 你好
