What are some common mistakes to avoid when using if statements with and/or conditions in PHP?

One common mistake when using if statements with and/or conditions in PHP is not using parentheses to clearly define the order of operations. This can lead to unexpected behavior and incorrect results. To avoid this, always use parentheses to group conditions together when using both and and or operators in the same if statement. 

// Incorrect way without parentheses
if ($condition1 && $condition2 || $condition3) {
    // Incorrect logic
}

// Correct way with parentheses
if (($condition1 && $condition2) || $condition3) {
    // Correct logic
}
