I’ve been working a bit more with PHP and JSON recently and one of the things that annoyed me quite a bit was the single line output of the json_encode()<\/a> function. \u00a0Here is an example:<\/p>\n

\r\n<?php\r\n$data = array(\r\n'foo' => 'bar',\r\n'bar' => 'qux',\r\n'blah' => 'blah',\r\n);\r\n\r\necho json_encode($data);\r\n?>\r\n<\/pre>\n
Poorly readable result (imagine having larger, more complex data structures like nested arrays):<\/p>\n
\r\n{"foo":"bar","bar":"qux","blah":"blah"}\r\n<\/pre>\n
Apparently, since PHP 5.4.0 it became much easier to optionally format the output with some indentation. \u00a0json_encode()<\/em> function has an $options parameter, which was given an extra option – JSON_PRETTY_PRINT<\/strong>. \u00a0Here is an updated example:<\/p>\n
\r\n<?php\r\n$data = array(\r\n 'foo' => 'bar',\r\n 'bar' => 'qux',\r\n 'blah' => 'blah',\r\n);\r\n\r\necho json_encode($data, JSON_PRETTY_PRINT);\r\n?>\r\n<\/pre>\n
And an updated output:<\/p>\n
\r\n{\r\n "foo": "bar",\r\n "bar": "qux",\r\n "blah": "blah"\r\n}\r\n<\/pre>\n
Very handy for debugging and for those bits of JSON that should be editable by hand.<\/p>\n\n","protected":false},"excerpt":{"rendered":"\n
