What are the limitations of using str_replace() for word translation in PHP?

Using str_replace() for word translation in PHP has limitations because it replaces exact matches of strings, which can lead to unintended replacements. To address this issue, you can use the strtr() function instead, which allows for multiple translations in one call and handles longer translations more efficiently. 

// Define an array with key-value pairs for word translations
$translations = array(
    'hello' => 'hola',
    'goodbye' => 'adiós'
);

// Use strtr() to translate words in a string
$string = "hello, how are you?";
$translated_string = strtr($string, $translations);

echo $translated_string;
