What potential pitfalls should beginners be aware of when using logical operators like "and" in PHP?

Beginners should be aware that using the "and" logical operator in PHP can lead to unexpected results if not used correctly. One common mistake is not understanding operator precedence, which can cause logical expressions to be evaluated in an unintended order. To avoid this issue, beginners should use parentheses to explicitly define the order of operations when using multiple logical operators in a single expression.

// Example of using parentheses to ensure correct evaluation order
if (($condition1 == true) and ($condition2 == true)) {
    // Code to execute if both conditions are true
}
