Is it advisable to use preg_quote in combination with preg_replace for safer string replacements in PHP?

When using preg_replace in PHP to replace strings, it is advisable to use preg_quote to escape any special characters in the search pattern to prevent unexpected behavior or errors. This helps ensure that the search pattern is treated as a literal string rather than a regular expression, making the replacement process safer and more reliable. 

$search = "special characters like . and +";
$replacement = "escaped characters";
$string = "Replace special characters like . and + with escaped characters.";

$search_pattern = preg_quote($search, '/');
$result = preg_replace('/' . $search_pattern . '/', $replacement, $string);

echo $result;
