Are there any best practices for efficiently replacing specific parts of a string in PHP?

When replacing specific parts of a string in PHP, it is best to use the str_replace() function. This function allows you to specify the substring you want to replace, the new substring you want to insert, and the original string. By using this function, you can efficiently replace specific parts of a string without having to manually manipulate the entire string. 

// Example of replacing specific parts of a string in PHP
$string = "Hello, World!";
$oldSubstring = "Hello";
$newSubstring = "Hi";

$newString = str_replace($oldSubstring, $newSubstring, $string);

echo $newString; // Output: Hi, World!
