Switch case is something that cannot be missed if we talk about any programming language. The following pointers will be covered in this Switch Case in PHP article,

 

What is a Switch Case?

In this article, we are going to talk about something called switch case in PHP and the basic idea behind the switch case is that we are going to do something different inside the browser depending on some kind of answer we might have. It is an alternative to a series of if statement, which does almost the same thing.

switch-case-in-phpA Variable is tested by switch-case statements against a series of values until it finds a match, and then executes the block of code corresponding to that match.

 

Moving on with this article on switch case in php

Code: Switch case in PHP

In our example, the answer is going to be a value assigned to some variable. So the way we write out a switch is by
switch()
{
}
though it looks similar to if statement, it is not exactly same though because in an if statement, you do actually have different conditions where in switch, you write all the different possible answers inside the curly brackets itself. So let’s go ahead and write out one different case

<?php
$x=1;
switch($x)
{
case 1:
echo "This answer is case 1";
break;
}

We can also assign string to the variable.

<?php
$x="number";
switch($x)
{
case 1:
echo "This answer is case 1";
break;
case "number";
echo "This answer is case number";
break;
}

Example- switch case in php- Edureka

Basically, we use break to prevent the code from running into the next case automatically. We use default statement, if no match is found.

<?php 
$company = "amazon"; 
switch($company) 
{ 
case "simplilearn": echo "Company choosed: simplilearn"; 
break; 
case "edureka": echo "Company choosed: edureka";
break; 
case "intellipaat": echo "company choosed: intellipaat"; 
break; 
default: echo "Company not found"; 
break;
 }
 ?>

With this, we come to an end of this article. I hope you have learned about switch case in PHP and the basic idea behind the switch case, that we have done something different inside the browser depending on some kind of scenario.
