php if else

php if else
In this lesson we will talk about php if else and what does it mean and what we can do with it
so if statement are using to verify a particular condition after it, for example
if you are not busy bring me a cup of coffee, the condition in this case is not busy, if it is true than he will bring you a cup of coffee,if not he will beat you hhhhhh just kidding he will not bring you the coffee cup,
So let's write some code

<?php
$p = "busy" ;
if ($p == "busy") {
echo "sorry i can't i'm busy" ;
}
?>

In this example we define a variable and we gave him the value of busy, and put a conditional statement after it to check if the variable p is equal to busy then he will print sorry i can't i'm busy 
So write this code and you will see in the screen this statment sorry i can't i'm busy 

Let's do other example with if and else
<?php
$p = "not busy" ;
if ($p == "busy") {
echo "sorry i can't i'm busy" ;
}
else {
echo "ok no probleme" ;
}
?>
In this example the program will check if the variable p equal to busy, but as we see it's not so he will scroll down to the else statement and do what is between brackets
