In what scenarios would using strtr() be more beneficial than str_replace in PHP?

strtr() would be more beneficial than str_replace in scenarios where you need to replace multiple characters or strings in a single operation. strtr() allows you to create a translation table where you can specify multiple replacements at once, which can be more efficient than making multiple calls to str_replace(). 

// Using strtr() to replace multiple characters in a string
$string = "Hello, world!";
$replacements = array("H" => "J", "e" => "i", "o" => "a");
$newString = strtr($string, $replacements);

echo $newString; // Output: Jilla, warld!
