PHP allows you to choose what action to take based on the result of a condition.
We can use if statements inside if statements. These statements are called Nested If Statements.
In PHP, there are 4 different types of Conditional Statements.
This tests the return value of the function, whose name is the value in the variable named fun("str1"), and given the arguments fun("str2") and the value of the variable named fun("str3").
Example:
If fun("str1") equals "x", fun("str2") equals 34, and fun("str3") equals "y", then the statement would look like:
if ( $x (34, $y) )
