WEBVTT 00:00.920 --> 00:04.190 So now we're going to learn the match statement. 00:04.190 --> 00:10.310 That's something similar to the switch statement though there are some differences. 00:10.340 --> 00:15.860 Let's start by creating a match PHP file and the PHP tag. 00:16.550 --> 00:24.320 So in this example I'd like to convert the HTTP status codes, which are always returned with every 00:24.320 --> 00:33.020 response from the server to some meaningful text that would basically describe of to which group this 00:33.020 --> 00:34.670 status belongs. 00:34.670 --> 00:37.490 And for that we're going to use the match statement. 00:37.490 --> 00:41.120 And already that's the first difference. 00:41.120 --> 00:49.970 I can immediately assign the result of the match statement to a variable, because match returns a value. 00:49.970 --> 00:54.140 So essentially it can be described as an expression. 00:54.140 --> 00:58.340 So with the switch statement that wasn't the case. 00:58.340 --> 01:01.880 You just used switch statement to execute some code. 01:01.880 --> 01:09.180 And you would have to assign something to the message variable in every single case for it to work the 01:09.180 --> 01:14.790 same way here, I can directly get the result from the match statement. 01:15.150 --> 01:17.100 Let's add a semicolon here. 01:17.100 --> 01:19.440 And how do you define cases? 01:19.440 --> 01:22.140 Well, this syntax here is short. 01:22.170 --> 01:25.230 Well it's shorter than in the switch statement. 01:25.740 --> 01:30.030 So I can just list cases like that 200 300. 01:30.030 --> 01:32.520 And I use this arrow symbol. 01:32.550 --> 01:35.670 Again these are just two characters together. 01:36.600 --> 01:38.340 And I return something. 01:38.340 --> 01:41.820 I don't have to write the return keyword or anything. 01:41.820 --> 01:45.270 Just whatever I type here is being returned. 01:45.270 --> 01:49.680 So for those codes we assume it's a success. 01:49.680 --> 01:51.990 Now obviously there are more HTTP codes. 01:51.990 --> 01:54.330 We are just having a simple example here. 01:54.510 --> 02:03.390 Then for 400 404 not found and 500 internal server error, we just return that. 02:03.390 --> 02:04.560 That's an error. 02:04.560 --> 02:12.900 And also we will have a default case that does an unknown status. 02:14.760 --> 02:17.800 Finally let's just Strauss echoed the message. 02:17.800 --> 02:21.190 And make sure we have a new line character. 02:22.570 --> 02:25.060 So another difference with the match statement. 02:25.060 --> 02:30.550 Comparing it to switch is that you don't need to use the break statement. 02:30.550 --> 02:35.350 So this is by default working more like the if statement. 02:35.350 --> 02:43.120 So we we are essentially trying to match the value of this expression to some specific values. 02:43.120 --> 02:47.950 And then we return a specific value if there is a match. 02:49.420 --> 02:50.560 So let's run it. 02:50.590 --> 02:53.260 We do PHP match PHP. 02:53.740 --> 02:57.580 That's an error because our status code was error. 02:57.580 --> 03:01.420 If I'm gonna try that with the success, this also works. 03:01.420 --> 03:09.850 And if I come up with something that doesn't make sense for HTTP, we get the unknown status. 03:11.320 --> 03:17.890 Another thing you should keep in mind when using match is that it is using the strict comparison, which 03:17.890 --> 03:23.590 means that not only will it compare a value, it will also compare the type. 03:23.590 --> 03:27.410 So there is no type coercion in the match statement. 03:27.410 --> 03:29.870 So essentially let me give you an example. 03:29.870 --> 03:36.500 With the switch statement it was loosely compared, which means that in case of the switch statement 03:36.530 --> 03:44.900 string 600 is the same as the number 600 because the type coercion is happening there. 03:45.230 --> 03:57.890 But with the strict comparison, the text 600 is different then the number 600, because here the match 03:57.890 --> 04:02.450 statement is going to be using the strict equality operator. 04:02.450 --> 04:05.480 So as a reminder, also checking the type. 04:07.760 --> 04:17.180 Now what also needs to be said about the match statement is that it was only introduced in PHP 8.0. 04:17.270 --> 04:21.380 So you need to have at least this version of PHP. 04:21.410 --> 04:23.240 It didn't exist previously. 04:23.240 --> 04:30.740 It's quite new, but I really love this match statement and I think it was really necessary to add something 04:30.740 --> 04:33.290 like this to the PHP language.
