What are some best practices for handling array values in PHP when replacing text?

When replacing text in PHP, it's important to handle array values properly to ensure that the replacement is done correctly for each element in the array. One best practice is to use a loop to iterate through the array and apply the replacement to each element individually. Another approach is to use array_map() function along with a callback function to perform the replacement on each element. Additionally, using regular expressions with preg_replace() can be helpful for more complex text replacements. 

// Example of replacing text in an array using a loop
$originalArray = ['Hello, world!', 'Goodbye, world!'];
$replacement = 'PHP';

foreach ($originalArray as $key => $value) {
    $originalArray[$key] = str_replace('world', $replacement, $value);
}

print_r($originalArray);
