Are there any differences between using the "!" symbol in PHP and in other programming languages like VB?

In PHP, the "!" symbol is used as a negation operator to reverse the truth value of an expression. This is similar to other programming languages like VB, where the "!" symbol is also used for negation. However, there may be differences in syntax or precedence rules when using the "!" symbol in different programming languages. 

$var = true;
if (!$var) {
    echo "Variable is false";
} else {
    echo "Variable is true";
}
