PHP Conditional Statements
Like most programming languages, PHP also allows you to write code that perform different actions based on the results of a logical or comparative test conditions at run time. This means, you can create test conditions in the form of expressions that evaluates to either true or false and based on these results you can perform certain actions.
There are several statements in PHP that you can use to make decisions:
The if statement
The if…else statement
The if…elseif….else statement
The switch…case statement
We will explore each of these statements in the coming sections.
The if statement is used to execute a block of code only if the specified condition evaluates to true…
You can enhance the decision making process by providing an alternative choice through adding an else statement to the if statement. The if…else statement allows you to execute one block of code if the specified condition is evaluates to true and another block of code if it is evaluates to false. It can be written, like this:
if…elseif…else a special statement that is used to combine multiple if…else statements.
