![]() PHP If statement is the conditional statement you can use when you want to test one condition and execute the code when the test is true. Same as in real life you can perform the conditional operation using the below type of conditional statements: Before taking any decision you always think of conditions, if you perform this task if you will get this type of result. These decisions help you to get the desired results as the output. In real life, you make certain decisions and based on this decision you perform different actions. These actions are based on the logic you want to perform using your code and get the result of the action.īy using the conditional statements you can perform various tests in your code and you can out certain actions based on the test either true or false. ![]() If you have many elseif blocks then you may consider using the switch statement of PHP.You can use PHP If and PHP Else if conditional statements in PHP to perform different actions. and logical operators like and, or, &, || etc. If statements contain statements that are only executed when the condition is satisfied. You may use comparison operators like =, !=, >, <, <= etc. ![]() If all conditions are false, the else part will execute and after that control will move to the next line of code outside of the if statement. If it returns as true, it will perform the given actions otherwise, it will move to the next elseif statement (if provided). You have to give an expression in the if statement which is evaluated. The if.else, elseif statements in PHP are used to make decisions based at some criteria. There you can use elseif or else that will relate to the first if statement. You may go further to use another nested if inside second if statement and so on.Īfter using the if statement (with else or elseif) inside the first if, close the curly bracket. This will start nested if where you can check another condition. So inside the curly brackets of first if statement, another if statement is used before you close it. In the example, following block of codes are used in the if and elseif statements of PHP: On the change event of dropdown, the same PHP file is called where I have used if with the elseif statement.Īs you select a color from the dropdown, a div with the same color will be displayed.įirst have a look at the demo followed by a little description: ![]() If-else statement is slightly different from if statement. In the drop-down, you can select a color. PHP if-else statement is executed whether condition is true or false. As you open the demo page, an HTML dropdown will be displayed. The PHP elseif statement with select dropdown, div, and CSSįollowing is an example to use if with elseif PHP statement. ![]() You may copy the code and try it in your PHP editor. If it is some other number the PHP else statement part will execute. Depending on what you wrote for the method in the form and using REQUEST in the php, REQUEST will use Get if GET is written for the method and REQUEST. If the given number is 3, it will be evaluated as true in the if statement, so the statement inside the if statement will execute. When you put a semicolon at the end of a condition, like this: if (choice1 choice2) you are telling. Only, the if.else statement is used in the example. In JavaScript semicolons mark the end of statements. In the example, I have simply declared a variable and assigned it a numeric value. I will explain both with visual examples in this tutorial, so you may understand how to use if.else with HTML or other web elements, as such PHP is generally used for web based projects.Ī simple example to start with – the if.elseīefore going to user selection based execution of a block in the if.else statement, in this example, I will simply use a static value to show how it works, to give an idea if you are a beginner. Note: If you have multiple lines to execute, enclose each block in curly brackets. ![]()
