Are there any best practices or conventions to follow when using the "!" symbol in PHP programming?

When using the "!" symbol in PHP programming, it is typically used as a logical NOT operator to negate a condition. It is important to use it carefully and in a way that is clear and understandable to other developers. It is a best practice to use parentheses to ensure the correct order of operations when using the "!" symbol. 

// Example of using the "!" symbol to negate a condition
$condition = true;

// Using the "!" symbol to negate the condition
if (!$condition) {
    // Code to execute if the condition is false
    echo "Condition is false";
} else {
    // Code to execute if the condition is true
    echo "Condition is true";
}
