What are some common pitfalls when using str_replace in PHP to replace multiple search terms in a file?

One common pitfall when using str_replace in PHP to replace multiple search terms in a file is that the function only accepts single values for both search and replace parameters. To overcome this limitation, you can use str_replace in a loop to iterate over an array of search terms and their corresponding replacements. 

$search_terms = array("search_term_1", "search_term_2", "search_term_3");
$replace_terms = array("replace_term_1", "replace_term_2", "replace_term_3");

$file_contents = file_get_contents("file.txt");

for($i = 0; $i < count($search_terms); $i++) {
    $file_contents = str_replace($search_terms[$i], $replace_terms[$i], $file_contents);
}

file_put_contents("file.txt", $file_contents);
