What are some alternative methods to using Regex for replacing occurrences in PHP?

Using string functions like str_replace or preg_replace can be an alternative to using Regex for replacing occurrences in PHP. These functions provide simpler and more straightforward ways to replace specific strings in a given text.

// Using str_replace to replace occurrences in a string
$text = "Hello, World!";
$newText = str_replace("Hello", "Hi", $text);
echo $newText;

// Using preg_replace to replace occurrences in a string with a regular expression
$text = "The quick brown fox jumps over the lazy dog.";
$newText = preg_replace("/brown/", "red", $text);
echo $newText;
