How To Request JSON API Data With JavaScript Or PHP

Here is the full PHP file. We can display the data in a table, for an example. This is often preferable when outputting HTML. There’s another way we can access the data in PHP. And here’s how to access the loop. So far, we’ve only used JSON feeds with key/value pairs, but it’s common to encounter nesting. Here’s another nerdy example, which we can save in a new file called wizards.json. We made a PHP array and encoded it. We’re going to create a JavaScript variable called data and apply the JSON string. Now we’ll use JavaScript built in JSON.parse() function to decode the string. From here we can access the data like a regular JavaScript object. And we can loop through each iteration with a for loop. That was easy! Now, we’ll probably need to access JSON from a URL. There’s an extra step involved, where we have to make a request to the file. Let’s just take the above JSON string and put it in data.json. Now we’ll make an XMLHttpRequest(). We’ll open the file (data.json) via GET (URL) request. From here, we’ll parse and work with all our JSON data within the onload function. Then finally, submit the request. Here’s the final code. Now you can also use the Fetch API to do the same thing. Read How to use the JavaScript Fetch API to Get JSON Data for an easier method to get this data. As you can see, it’s not too difficult to retrieve a JSON feed with plain JavaScript. However, it’s even easier with jQuery, using the getJSON() function. If you don’t know how jQuery works, you’ll need to load the jQuery JavaScript library before any of this custom code.
’ characters, parentheses, variable names, and so on, all become part of the value of the variable you are defining. See Defining Multi-Line Variables, for a complete explanation of define. The first command in this example runs Yacc on the first prerequisite of whichever rule uses the canned sequence. The output file from Yacc is always named y.tab.c. The second command moves the output to the rule’s target file name. To use the canned sequence, substitute the variable into the recipe of a rule. You can substitute it like any other variable (see Basics of Variable References). Because variables defined by define are recursively expanded variables, all the variable references you wrote inside the define are expanded now. This is a realistic example, but this particular one is not needed in practice because make has an implicit rule to figure out these commands based on the file names involved (see Using Implicit Rules). In recipe execution, each line of a canned sequence is treated just as if the line appeared on its own in the rule, preceded by a tab.
In this case, n.c is called an intermediate file. Once make has decided to use the intermediate file, it is entered in the data base as if it had been mentioned in the makefile, along with the implicit rule that says how to create it. Intermediate files are remade using their rules just like all other files. But intermediate files are treated differently in two ways. The first difference is what happens if the intermediate file does not exist. If an ordinary file b does not exist, and make considers a target that depends on b, it invariably creates b and then updates the target from b. But if b is an intermediate file, then make can leave well enough alone: it won’t create b unless one of its prerequisites is out of date. This means the target depending on b won’t be rebuilt either, unless there is some other reason to update that target: for example the target doesn’t exist or a different prerequisite is newer than the target.
