json_encode() - JSON_PRETTY_PRINT Option
How to use the JSON_PRETTY_PRINT option in the json_encode() call to generate a pretty looking JSON text string?
✍: FYIcenter.com
If you want a pretty looking JSON text string, you can call json_encode() with the JSON_PRETTY_PRINT option. It will add line breaks and insert 4 space characters to indent level of sub structures in the output.
Here is a PHP example that shows you how to use the JSON_PRETTY_PRINT when calling json_decode():
<?php "dev.fyicenter.com", "1"=>array("0"=>"PHP","1"=>"JSON") ); print("\nInput: "); var_dump($var); print("Output: ".json_encode($var,JSON_PRETTY_PRINT)."\n"); $var = array( "site"=>"dev.fyicenter.com", "topics"=>array("PHP"=>"Y","JSON"=>"Y") ); print("\nInput: "); var_dump($var); print("Output: ".json_encode($var,JSON_PRETTY_PRINT)."\n"); ?>
If you run the above PHP code through the PHP engine, you get the following output:
>\fyicenter\php\php.exe json_encode_pretty.php Input: array(2) { [0]=> string(17) "dev.fyicenter.com" [1]=> array(2) { [0]=> string(3) "PHP" [1]=> string(4) "JSON" } } Output: [ "dev.fyicenter.com", [ "PHP", "JSON" ] ] Input: array(2) { ["site"]=> string(17) "dev.fyicenter.com" ["topics"]=> array(2) { ["PHP"]=> string(1) "Y" ["JSON"]=> string(1) "Y" } } Output: { "site": "dev.fyicenter.com", "topics": { "PHP": "Y", "JSON": "Y" } }
