How does the use of {} in scripts affect the performance of PHP code, especially with long if statements?

Using curly braces {} in scripts can improve the readability of long if statements by clearly defining the scope of the code block. This can make the code easier to understand and maintain. However, using curly braces does not have a significant impact on the performance of PHP code.

// Example of using curly braces in a long if statement
if ($condition) {
    // Code block
    echo "Condition is true";
} else {
    // Code block
    echo "Condition is false";
}
