How does the double-pipe (||) symbol differ from the OR operator in PHP?

The double-pipe (||) symbol and the OR operator in PHP are essentially the same in terms of functionality, as they both perform logical OR operations. However, the double-pipe symbol has a higher precedence than the OR operator, which means it is evaluated first in an expression. This can lead to unexpected results if used in combination with other operators. To ensure the correct evaluation order, it is recommended to use parentheses to explicitly define the order of operations.

// Using parentheses to explicitly define the order of operations
$result = ($a || $b) && $c;
