How does PHP handle type conversion in comparisons?

When comparing values of different types in PHP, type conversion can occur, which may lead to unexpected results. To avoid this, you can use strict comparison operators (=== and !==) which not only compare values but also their types. This ensures that values are not converted during the comparison, resulting in more predictable outcomes. 

$value1 = 5;
$value2 = '5';

// Using strict comparison to compare values without type conversion
if ($value1 === $value2) {
    echo 'Values are equal.';
} else {
    echo 'Values are not equal.';
}
