PHP IF ELSE CODE
PHP if else statements are used when you want to execute some code if a condition is true and another code if a condition is false. Here the program will output “Condition matched”, since the condition checked by if statement is true. Read more about conditional statements in our PHP if else Tutorial. It also applies to any variation of the if conditional, such as if.elseif and if.else. It’s a one-way branching in which the statements will only execute if the given expression is true. The endif keyword is used to mark the end of an if conditional which was started with the if (.): syntax. The code you can see in the example is meant to output the text Good day. Let's see if else PHP statements in action to get a better idea. If it is not, the code next to the else statement is executed as an alternative. If securty is enabled, only PHP functions from phpfunctions. PHP is no exception to this.PHP if statement, as the name suggests, is used to make a decision and execute a block of code if only the condition checked is matched. if else PHP statements execute certain code if the condition specified next to the if part proves true. All PHP conditionals and functions are recognized, such as, or, &, and, isarray(), etc. Most programming languages evaluate conditionals from left to right. The first thing that you should always keep in mind is the order that conditionals get evaluated. The syntactic meaning is slightly different (if you're familiar with C, this is the same behavior) but the bottom line is that both would result in exactly the same behavior. But knowing how PHP evaluates them lets you remove and/or combine conditionals. In PHP, you can also write 'else if' (in two words) and the behavior would be identical to the one of 'elseif' (in a single word). This is so often misunderstood when using conditionals. How does PHP evaluate multiple conditionals?įirst, let’s take a look at how PHP evaluates conditionals. We’ll go over some programming techniques that can help make conditionals more manageable.
This is what this article will try to help you with. if.elseif.else statement - executes different codes for more than two conditions. if.else statement - executes some code if a condition is true and another code if that condition is false. That said, it’s possible to develop good programming habits with conditionals. In PHP we have the following conditional statements: if statement - executes some code if one condition is true. In case the expression evaluates to false. If the expression evaluates to true, PHP executes the statement. These are: If statement is used to perform an action if a single condition is true. (This is also a problem with loops.) This can lead to code that’s complex and hard to read or even test. In this syntax, PHP evaluates the expression first. PHP If Else statement is a conditional statement, which can be used in various forms to check a condition or multiple conditions and to perform the specified action or actions, if the particular condition is true. It allows you to check if a conditional statement returns true if your previous statement returns false. You can also write the elseif statement as else if. This is what is called the elseif statement. In fact, they’re so easy to use that you can develop some bad habits around them. if else PHP statements execute certain code if the condition specified next to the if part proves true. The PHP language allows you to add a conditional statement after an if statement. There’s just no way around it.īut conditionals (that’s what we call these control structures) fit in the “easy to learn, hard to master” category. With a few exceptions, you’ll use at least one per function or method that you write.
No set of control structures is more pervasive in programming than if, elseif and else. In this syntax, if the expression is true, PHP executes the code block that follows the if clause. The PHP if statement is very similar to other programming languages use of the if statement, but for those who are not familiar with it, picture the.
