➤ A conditional statement in PHP is a way to control the flow of a program based on certain conditions. The "condition" is a boolean expression that evaluates to either true or false. If the condition is true, the code within the curly braces will be executed. If the condition is false, the code will be skipped. Other conditional statements such as else and elseif can also be used to specify different actions to be taken if the initial condition is not met.

If-else Statement
➤ The if-else statement is used to execute a block of code if a certain condition is true and another block of code if the condition is false.
The syntax for an if-else statement is as follows:
if (condition) {
// code to be executed if condition is true
} else {
// code to be executed if condition is false
} 

 //Here is an example of using an "if-else" statement in PHP:
$num = 5;
if ($num > 0) {
echo "$num is positive.";
} else {
echo "$num is not positive.";
}

In this example, the condition being tested is whether the variable $num is greater than 0. If it is, the code within the first set of curly braces will be executed and the message "5 is positive." will be displayed. If it is not, the code within the second set of curly braces will be executed and the message "5 is not positive." will be displayed.
