How can PHP developers avoid errors related to comparing string fragments within an array?

When comparing string fragments within an array in PHP, developers should ensure they are using strict comparison operators (===) instead of loose comparison operators (==) to avoid unexpected errors. Strict comparison operators compare both the values and data types, which helps prevent unintended type coercion. By using strict comparison operators, PHP developers can accurately compare string fragments within an array without encountering errors related to data type mismatch. 

$array = ["10", "20", "30"];
$fragment = "10";

foreach ($array as $value) {
    if ($value === $fragment) {
        echo "Found matching fragment: " . $value;
    }
}
