How can PHP developers prevent unintentional assignment errors when comparing values in arrays within for loops?

PHP developers can prevent unintentional assignment errors when comparing values in arrays within for loops by using strict comparison operators (=== and !==) instead of loose comparison operators (== and !=). Strict comparison operators not only compare the values of variables but also their types, which can help avoid unexpected behavior. Additionally, developers should pay attention to the order of operands in comparison statements to ensure that they are comparing values correctly. 

$numbers = [1, 2, 3, 4, 5];

for ($i = 0; $i < count($numbers); $i++) {
    if ($numbers[$i] === 3) {
        echo "Value 3 found at index $i";
    }
}
