How can the order of operations in PHP affect the outcome of code execution?

The order of operations in PHP can affect the outcome of code execution by determining the sequence in which different operations are performed. For example, if parentheses are not used correctly, the order of operations may lead to unexpected results. To ensure the desired outcome, it is important to follow the correct order of operations by using parentheses to explicitly define the order in which operations should be executed.

// Incorrect order of operations
$result = 10 + 5 * 2; // Result will be 20 instead of 15

// Correct order of operations using parentheses
$result = (10 + 5) * 2; // Result will be 30
