How can Quoted-Printable encoding affect PHP code manipulation?

Quoted-Printable encoding can affect PHP code manipulation by encoding special characters in a way that can interfere with the execution of PHP code. To solve this issue, you can use the PHP function `quoted_printable_decode()` to decode the quoted-printable encoded string before manipulating the PHP code. 

// Decode the quoted-printable encoded string before manipulating PHP code
$quotedPrintableString = 'This is a quoted-printable encoded string';
$decodedString = quoted_printable_decode($quotedPrintableString);

// Now you can safely manipulate the PHP code
eval($decodedString);
