How can the use of multiple operators in PHP code impact code readability and maintainability?

Using multiple operators in PHP code can make the code harder to read and maintain. It can lead to confusion about the order of operations and make it difficult to understand the logic of the code. To improve readability and maintainability, it's recommended to break down complex expressions into smaller, more manageable parts and use parentheses to clearly define the order of operations. 

// Example of breaking down a complex expression into smaller parts
$condition1 = $var1 > 0 && $var2 < 10;
$condition2 = $var3 == 'foo' || $var4 != 'bar';

if ($condition1 && $condition2) {
    // Code block
}
