What are the best practices for handling character replacement in PHP strings?

When handling character replacement in PHP strings, it is best practice to use the str_replace() function. This function allows you to specify the character or characters you want to replace, as well as the character or characters you want to replace them with. By using this function, you can easily and efficiently replace characters in a string without manually iterating through each character. 

// Replace all occurrences of 'a' with 'b' in the string
$string = "abcde";
$newString = str_replace('a', 'b', $string);
echo $newString;
