What are the potential pitfalls of using str_replace or array_replace functions in PHP for value replacement?

Using str_replace or array_replace functions in PHP for value replacement can lead to unintended consequences if the search value is found within the replacement value. This can result in an infinite loop or incorrect replacements. To avoid this issue, you can use a loop to replace values one by one, ensuring that each replacement is done correctly without causing conflicts. 

$array = ['apple', 'banana', 'cherry'];
$search = 'a';
$replace = 'e';

foreach ($array as $key => $value) {
    $array[$key] = str_replace($search, $replace, $value);
}

print_r($array);
