Are there any built-in PHP functions or libraries that can assist in selectively replacing strings based on specific criteria?

When you need to selectively replace strings based on specific criteria in PHP, you can use the `preg_replace()` function along with regular expressions to define the criteria for replacement. This function allows you to search for a pattern in a string and replace it with a specified value. By crafting the regular expression pattern to match your specific criteria, you can achieve selective string replacement. 

// Example code to selectively replace strings based on specific criteria
$string = "Hello World! Replace this text selectively.";
$pattern = "/\bReplace\b/i"; // Match the word 'Replace' case-insensitively
$replacement = "Modified"; // Replacement text

// Perform selective string replacement based on the specified criteria
$newString = preg_replace($pattern, $replacement, $string);

// Output the modified string
echo $newString;
