This read will be easy" Įcho "I am a complete beginner. In this syntax, if the expression is true, PHP executes the code block that follows the if clause. php $know_js = false Įcho "I know Javascript. In PHP we have the following conditional statements: if statement - executes some code if one condition is true if.else statement - executes some code if. Great, now let's be more PHP specific and translate the above example to valid if/else statement syntax. It worth to mention that while, for and their derived are also called loops, because they execute a piece of code while the condition is met. foreach - executes a block of code for each element of an array.for - executes a block of code a given number of times.do / while - executes a block of code once, and then repeats it as long as the condition is met.while - repeats a block of code as long as the condition is met. ![]() Conditions are placed inside parentheses immediately after the if and else if.

PHP have the following conditional statements when it comes to performing different actions depending if a condition is By the way, pseudo-code is a simplified way of writing natural language code without taking into consideration the programming-specific syntax. If not, just read this tutorial carefully because it will be useful when learning any other programming language.ĭid you paid attention to what I've just said? The upper paragraph contains a conditional statement. So if you already know some other programming language this will be an easy read. Sections, each conditional line must end with a colon and the whole statementĪ Boolean variable is one that holds a true or a false value.The if/else condition is the most simple form of conditional processing and you will find it in any programming language. If the conditional statement is made of different if, elseif, and/or else The Body of an If/Else Conditional Statement is there a possibility to write a shorthand if, ELSE IF, else statement for php. The formula to follow is: if( variable-or-value1 operator1 variable-or-value2)Įlseif( variable-or-value1 operator_n1 variable-or-value2)Įlseif(variable-or-value3 operator2 variable-or-value4)Įlseif(variable-or-value5 operator3 variable-or-value6) 12 This question already has answers here : How to replace 'if' statement with a ternary operator ( : ) (16 answers) Closed 8 years ago. ![]() If none of the elseif comparisons applies, you can add a last else statement. $incomeTax = 38.40 + ($rawSalary * 0.15) Įlseif(htmlspecialchars($_POST) = 'Monthly') $incomeTax = 35.50 + ($rawSalary * 0.15) Įlseif(htmlspecialchars($_POST) = 'Semimonthly') Most people grasp the syntax rather quickly and will within short time be able to produce a script that works using. $incomeTax = 99.10 + ($rawSalary * 0.25) Įlseif(htmlspecialchars($_POST) = 'Biweekly') $rawSalary = $hourlySalary * $timeWorked $payrollPeriod = htmlspecialchars($_POST) ![]() It also applies to any variation of the if conditional, such as if.elseif and if.else. $hourlySalary = (float)htmlspecialchars($_POST) Definition and Usage The endif keyword is used to mark the end of an if conditional which was started with the if (.): syntax. $employeeName = htmlspecialchars($_POST) You can include any HTML code anywhere in the loop as longĪs you delimit the loop code with its own PHP delimitiers. $monthl圜harges = $consumption * $pricePerCCF Here is an example: įont-family: Georgia, "Times New Roman", Times, serif The section where you define what to do about aĬonditional statement is referred to as its body. Here is an example of using the webpages: The redirect needs to be sent before absolutely any screen output, so where ever in your code where the first bit of html, echo statements.etc is at, the.
