What are the differences between the OR and || operators in PHP when used in logical expressions?

The main difference between the OR and || operators in PHP when used in logical expressions is their precedence. The OR operator has a lower precedence than the || operator, which means that the || operator will be evaluated first. This can lead to unexpected results if both operators are used in the same expression. To avoid this issue, it is recommended to use the || operator for logical operations to ensure consistent behavior.

// Using || operator for logical operations to ensure consistent behavior
if ($condition1 || $condition2) {
    // Code block
}
