What are the best practices for optimizing resource usage when performing string searches in PHP scripts?

When performing string searches in PHP scripts, it is important to optimize resource usage to ensure efficient performance. One way to achieve this is by using built-in PHP functions such as strpos() or preg_match() instead of custom functions. Additionally, avoid unnecessary string manipulation and use regular expressions efficiently to minimize processing time. 

// Example of optimizing resource usage for string searches in PHP

// Using strpos() function for simple string searches
$string = "Hello, World!";
$search = "World";
if(strpos($string, $search) !== false) {
    echo "String found!";
} else {
    echo "String not found.";
}

// Using preg_match() function for more complex string searches
$string = "The quick brown fox jumps over the lazy dog.";
$search = "/\b(quick|brown|fox)\b/i"; // Search for words "quick", "brown", or "fox" ignoring case
if(preg_match($search, $string)) {
    echo "String found!";
} else {
    echo "String not found.";
}
