How can arrays be effectively used to prevent multiple character replacements in PHP encryption?

To prevent multiple character replacements in PHP encryption, you can use arrays to map specific characters to their encrypted counterparts. By using arrays, you can ensure that each character is only replaced once during encryption, preventing repetitive replacements and maintaining the integrity of the encrypted text. 

// Define an array to map characters to their encrypted counterparts
$encryptionMap = [
    'a' => 'x',
    'b' => 'y',
    'c' => 'z',
    // Add more mappings as needed
];

// Encrypt the text using the encryption map
$text = "abc";
$encryptedText = strtr($text, $encryptionMap);

echo $encryptedText; // Output: "xyz"
