Decipher PHP if statements effortlessly! This guide breaks down conditional logic with practical examples, empowering you to craft dynamic and robust code.
Conditional statements are used to perform different actions based on different conditions.
Very often when you write code, you want to perform different actions for different conditions. You can use conditional statements in your code to do this.
In PHP we have the following conditional statements:
if
statement - executes some code if one condition is trueif...else
statement - executes some code if a condition is true and another code if that condition is falseif...elseif...else
statement - executes different codes for more than two conditionsswitch
statement - selects one of many blocks of code to be executedThe if
statement executes some code if one condition is true.
if (condition) {
code to be executed if condition is true;
}
Output "Have a good day!" if 5 is larger than 3:
if (5 > 3) {
echo "Have a good day!";
}
We can also use variables in the if
statement:
Output "Have a good day!" if $t
is less than 20:
$t = 14;
if ($t < 20) {
echo "Have a good day!";
}
