WEBVTT 00:00.740 --> 00:06.710 The for each loop has to be the simplest one to understand and to use. 00:07.580 --> 00:15.800 As the name might suggest, the idea is simple just go over every single item from the items array. 00:15.860 --> 00:24.320 Optionally also get the key, which might be the actual key from the associative array or an index, 00:25.550 --> 00:34.700 and get every single value and for every one of those values and optionally keys run the statements 00:34.700 --> 00:39.200 or the actual loop body and then you are done. 00:39.230 --> 00:43.910 So as a quick reminder we've seen arrays and the types of arrays. 00:43.940 --> 00:49.670 I haven't explained them in depth yet but we've used arrays before. 00:49.670 --> 00:57.680 So this is just this compound type where you have multiple items indexed by numbers starting with zero 00:57.710 --> 01:01.190 or indexed by keys. 01:01.640 --> 01:04.660 And they can also be Dimensional. 01:06.400 --> 01:09.910 So let's see an example of the for each loop. 01:10.660 --> 01:12.460 So let's see a quick example of a. 01:12.460 --> 01:14.680 For each loop let's create a. 01:14.710 --> 01:18.790 For each PHP file add the starting tag. 01:18.820 --> 01:22.840 And in this example we're going to use a basket. 01:23.080 --> 01:25.720 That would be an array associative array. 01:25.720 --> 01:29.230 So we've seen that on the diagram before there are keys. 01:29.230 --> 01:32.080 And keys have the values associated. 01:32.080 --> 01:36.310 So as keys I'm going to use the things that we can have in the basket. 01:36.310 --> 01:42.580 So I can have three apples and maybe four bananas. 01:42.580 --> 01:50.500 And we're going to use for each to just count every single item and maybe just display how many items 01:50.500 --> 01:52.750 of specific type someone has in a basket. 01:52.780 --> 01:58.540 Now also keep in mind that this symbol symbol here, this arrow that are actually those two characters 01:58.540 --> 02:01.540 placed together, it's just called ligature. 02:01.540 --> 02:05.680 And this is a thing that I have in my editor. 02:05.680 --> 02:11.010 So just remember those are two characters placed together. 02:11.250 --> 02:14.280 And now we're going to count the items. 02:14.280 --> 02:19.230 So let's use a variable called total initialized with zero. 02:19.230 --> 02:21.750 And now the for each loop. 02:21.780 --> 02:24.090 So we iterate over basket. 02:24.090 --> 02:26.730 So that's the array we're gonna go over. 02:26.760 --> 02:28.470 We use the as keyword. 02:28.470 --> 02:35.490 And first we type the name of the variable that will represent the current key. 02:35.520 --> 02:37.800 Then again this arrow symbol. 02:37.800 --> 02:43.380 And then we type the variable name that will represent the current value. 02:43.410 --> 02:47.520 So what this means is we're going to go over the basket array. 02:47.520 --> 02:55.590 And this body inside the loop will be run for every item, which in this case is the key. 02:55.590 --> 03:00.240 And for every quantity which is this value. 03:00.270 --> 03:03.510 Now keep in mind that the key is optional. 03:03.540 --> 03:10.470 This is also a valid for each loop where you're gonna skip the keys and only care about values. 03:10.470 --> 03:12.740 Now that's sometimes the case. 03:12.740 --> 03:15.500 In our case, we care about both. 03:15.710 --> 03:19.580 So let me just display the count of specific item. 03:19.580 --> 03:22.820 So I'm gonna do item equals. 03:25.340 --> 03:26.390 Quantity. 03:26.870 --> 03:30.650 Add a new line so the output is visible. 03:30.650 --> 03:36.860 And I need to remember about adding to the total quantity of items. 03:36.860 --> 03:38.990 So I can do it this way. 03:38.990 --> 03:49.910 Either reassign total as total plus quantity or use a shorthand which would be a plus equals, which 03:49.910 --> 03:54.590 means add the value on the right to the variable on the left. 03:54.860 --> 03:56.210 I'm going to use this shortcut. 03:56.210 --> 04:02.990 And finally we'll just say total items equals total. 04:03.020 --> 04:04.310 Add a new line. 04:04.310 --> 04:05.480 And that's it. 04:05.510 --> 04:09.470 Now let's run PHP for each PHP. 04:09.500 --> 04:10.190 There it is. 04:10.190 --> 04:15.410 We've got three apples, four bananas, and seven items in total.
