What potential pitfalls should developers be aware of when using var_export() with binary characters like chr(0)?

When using var_export() with binary characters like chr(0), developers should be aware that var_export() may not handle these characters correctly and may introduce errors in the output. To avoid this issue, developers can use the base64_encode() function to encode the binary data before passing it to var_export() and then decode it back using base64_decode() when needed.

$data = chr(0); // binary data
$encoded_data = base64_encode($data);
$exported_data = var_export($encoded_data, true);
$decoded_data = base64_decode($exported_data);
