![]() ![]() PHP if statement is used to execute some code, if a condition is evaluated to true otherwise if the condition is evaluated to false, execute nothing, or execute some other code. If you have many elseif blocks then you may consider using the switch statement of PHP.PHP Overview PHP Tutorial PHP Introduction PHP Installation PHP Basics PHP Basics PHP Syntax PHP Data Types PHP Variables PHP Constants PHP Print and Echo Statements Operators PHP Operators PHP Arithmetic Operators PHP Assignment Operators PHP Comparison Operators PHP Logical Operators PHP Ternary Operator PHP Concatenation Operators Decision Control Structures PHP Decision Making PHP if else statement PHP elseif statement PHP switch statement Loop Control Structures PHP Looping PHP while loop PHP do-while PHP for loop PHP foreach loop Functions PHP Date and Time PHP Functions PHP String Handling Functions PHP Include and Require PHP Headers PHP File Handling PHP Cookies PHP Sessions PHP Sending Emails Compare Strings In PHP array_diff() Function in PHP array_merge() Function in PHP array_search() Function in PHP eval() in PHP preg_replace() Function in PHP URL Encoding and Decoding with PHP sleep() Function in PHP strlen() Function in PHP ksort() Function in PHP strlen() Function in PHP gettype() Function in PHP Forms PHP GET and POST PHP Server Side Form Validation PHP File Upload PHP Classes and Objects PHP Inheritance What is stdClass in PHP? PHP OOP Terminology PHP Access Modifiers Miscellaneous PHP Arrays PHP RSS Feed PHP Composer Environment Variables in PHP PHP Error Handling report this ad and logical operators like and, or, &, || etc. ![]() 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. When we want to execute some code when a condition is true, and some other code when that condition is false, then we use the if. 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: In the drop-down, you can select a color. 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. 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. Only, the if.else statement is used in the example. 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.
