Pretty-Printing JSON with PHP

💻📝 Pretty-Printing JSON with PHP: Making Your Data Look Beautiful 😍🌈

If you've ever worked with JSON data in PHP, you might have encountered the issue of your JSON output looking less than pretty. 🤔😕

You know, the kind of JSON that looks like a tangled mess of characters, making it hard to read and understand. 😫🙈

Well, fear not! 🥳 In this blog post, we're going to address this common issue and provide you with easy solutions to pretty-print your JSON output using PHP. 🎉🙌

So, let's get started! 🚀

Understanding the Problem

To understand the issue, let's take a look at an example script that outputs JSON data:

$data = array('a' => 'apple', 'b' => 'banana', 'c' => 'catnip');
header('Content-type: application/json');
echo json_encode($data);

The output of this script looks like this:

{"a":"apple","b":"banana","c":"catnip"}

Now, this might be fine for small amounts of data, but when you're dealing with larger JSON structures, it quickly becomes unreadable. 😱

The Solution: JSON_PRETTY_PRINT

Thankfully, PHP provides an easy solution for pretty-printing JSON. 🙌🎉

When encoding your JSON, you can use the JSON_PRETTY_PRINT flag as a parameter to json_encode(). This flag formats the JSON output in a more human-readable way, adding indentation and line breaks. 😍🌈

Here's the updated code:

$data = array('a' => 'apple', 'b' => 'banana', 'c' => 'catnip');
header('Content-type: application/json');
echo json_encode($data, JSON_PRETTY_PRINT);

And voila! 🎉🌟 The output will now look like this:

{
    "a": "apple",
    "b": "banana",
    "c": "catnip"
}

The Facebook Solution 🚀

You might be wondering if PHP can pretty-print JSON without the JSON_PRETTY_PRINT flag. Well, it turns out that someone at Facebook found a cute little hack to achieve this. 😎💡

By setting the pre tag as the content-type, PHP will format the JSON as if it were preformatted text, resulting in a pretty-printed output. 😏💪

Here's the modified code:

$data = array('a' => 'apple', 'b' => 'banana', 'c' => 'catnip');
header('Content-type: text/html');
echo '<pre>' . json_encode($data) . '</pre>';

And guess what? 🙌🌈 The output will look just as pretty as before!

{
    "a": "apple",
    "b": "banana",
    "c": "catnip"
}
