How can hardware limitations affect PHP scripts, and what are some common issues to look out for?

Hardware limitations can affect PHP scripts by causing performance issues, such as slow execution times or memory constraints. Common issues to look out for include running out of memory when processing large datasets or exceeding CPU limits when handling intensive calculations. To address these issues, optimize your code for efficiency, use caching mechanisms to reduce server load, and consider upgrading your hardware if necessary. 

// Example of optimizing code for efficiency by using a more efficient algorithm
// Instead of looping through an array to find a specific value, use array_search() for faster results

$haystack = ['apple', 'banana', 'orange', 'grape'];
$needle = 'orange';

$key = array_search($needle, $haystack);
if ($key !== false) {
    echo "Found at index: " . $key;
} else {
    echo "Not found";
}
