In what scenarios would the strtr function in PHP be more suitable than str_replace?

The strtr function in PHP would be more suitable than str_replace when you need to replace multiple occurrences of different strings in a single operation. Str_replace is more suitable for replacing a single occurrence of a specific string. Strtr allows you to define a translation table where each key is replaced with its corresponding value. 

// Using strtr to replace multiple occurrences of different strings
$trans = array("hello" => "hi", "world" => "planet");
$string = "hello world!";
$new_string = strtr($string, $trans);

echo $new_string; // Output: "hi planet!"
