Finally, we learned how using switch-case can be faster than if-else blocks in certain situations. We also saw how to write case statements that cover multiple conditions. There is only one default in the switch statement. ![]() ![]() The keyword "break" means "get out of the switch/case statement", and has the effect of stopping PHP from executing the actions of all subsequent cases after its match. In this tutorial, I showed you how to use switch-case statements in PHP in place of if-else blocks to execute code conditionally. Essential points about switch case in PHP The default is an optional statement. This might not seem very helpful at first, but there are many situations where it comes in useful - not the least of which is trying to program a script to print out the song "The 12 Days of Christmas"! With the use of the switch statement you can check for all these conditions at once, and the great thing is that it is actually more efficient programming to do. This is because once PHP finds a match in its case list, it will execute the action of that match as well as the actions of all matches beneath it (further down on your screen). Secondly, each of our case actions end with "break ". The switch-case statement is an alternative to the if-elseif-else statement, which does almost the same thing. Firstly, there is no word "case" before "default" - that's just how the language works. Rounds all values in a timeframe and groups them. For example, ago (1h) is one hour before the current clock's reading. There are two important things to note in the PHP switch/case statement code. Returns the time offset relative to the time the query executes. Switch/case statements are used to check all sorts of data, and as you can see they take up much less room than equivalent if statements. Using switch/case statements, we can rewrite the previous mess of if statements like this: Unique rules to find Bugs, Vulnerabilities, Security Hotspots, and Code Smells in your PHP code. More often than not, you want to compare a variable with different values, and based on that you want to execute a piece of code. The syntax for the switch.case statement is as follows: main. You must see that in every case statement block there is a break. In many occasions, you may want to compare the same variable (or expression). Switch.Case - PHP Basics Intro PHP Basics PHP Advance PHP OOP The switch statement is used to select one of many blocks of code to be executed. As it seems something like a condition that will get executed by default. In a switch/case block you specify what you are checking against, then give a list of possible values you want to handle. In PHP, the switch statement is considered as an alternative to if-elseif-else statements. The switch statement is similar to a series of IF statements on the same expression. PHP has a solution to this, and it is called switch/case statements. × PHP Tutorial PHP HOME PHP Intro PHP Install PHP Syntax PHP Variables PHP Echo / Print PHP Data Types PHP Strings PHP Constants PHP Operators PHP If.Else.As you can see, here we're just trying to find out which piece of code we should execute, however it requires a lot of code because of the way if statements work.
