[RESOLVED] json_encode output's display

blackhorse

<?php
$arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);

echo json_encode($arr);
?>

The above example will output:

{"a":1,"b":2,"c":3,"d":4,"e":5}

How can I make the out put like this following

{"a":1,
"b":2,
"c":3,
"d":4,
"e":5}

or like
{
"a":1,
"b":2,
"c":3,
"d":4,
"e":5
}

Make it easy for human reading, specially when json has long text value to return.

An ugly solution I did before is instead of call json_encode on $arr, but instead, I can loop through $arr, can json_encode on each array element and attach link break after each json encoded array element.

But I don't want to do that.

Haha.
Takes some code to do it. But I did 🙂

<?php

$arr = array ('a'=>1,'b'=>2,'c'=>3,'d'=>4,'e'=>5);

$str1 = json_encode($arr);
$str2 = trim($str1,'{}');   // remove { and }
$arr3 = explode(',',$str2); // chop at comma into array
foreach($arr3 AS $str4)     // loop array and echo
    echo $str4.'<br />';

?>

I had done that just like you did. Like I added in my post, I Loop through the array and json encode each element instead of json encode whole array once. But I want to drop that idea.

I have huge json export, and to make it human readable is not as important as the performance. json is for computer program to read in the first place. I was just trying to see if there is an easy way to display one element one line so the programmer would be easy to read it too in the process.

There is possibly some easier way.
Lets see if somebody post it ....

If by "easy" you mean fewer lines of code, and if you can safely assume there are no commas in any of the values, you could do this:

$arr = array('a' => 1, 'b' => 2, 'c' => 3, 'd' => 4, 'e' => 5);
$json_str = json_encode($arr);
echo str_replace(',', ',<br />', $json_str);

But if, as you say, it's just to display the data to the programmer, why not simply decode it and display the key and value pairs? Time spent searching for inconsequential optimization is wasted time.

Rather than messing around with the code (and possibly introducing additional bugs in the process), "the programmer" could perhaps use a better tool for looking at JSON responses. The one I use is part of the Firebug extension.

Thanks, that is exactly what I am looking for. Didn't know firebug has it.
