PHP Conditional Statements
There are many statements in PHP that you can use to perform different actions which is given below:

Now Let’s start to explain each of these conditions statements see below:
PHP – The if Statement
The if statement is used to execute some code only if the condition is true.
Syntax:
if (condition) {
//code to be executed here
}
Flowchart:

The if…else statement executes some code if a condition is true and another block of code if it is false.
Syntax:
if (condition) {
code to be executed if condition is true;
} else {
code to be executed if condition is false;
}
Example
<?php $num=12; if($num%2==0){ echo "$num is even number"; }else{ echo "$num is odd number"; } ?>
Output:
PHP – The if…elseif…else Statement
The if…elseif…else a special statement that is used to more than two conditions.
Syntax:
if (condition) {
code to be executed if this condition is true;
} elseif (condition) {
code to be executed if first condition is false and this condition is true;
} else {
code to be executed if all conditions are false;
}
Example
