Hey guys,

How can I echo the name of one person with the lowest level in array like this?

Code: Select all

"test_subjects": {
		"5059844": {
			"name": "TylerDurden",
			"level": "25"
		"4270364": {
			"name": "Bob",
			"level": "23"
		"5536597": {
			"name": "gandalf",
			"level": "27"
		"4762201": {
			"name": "Neo",
			"level": "21"
		"2871510": {
			"name": "Sergey",
			"level": "21"
So I'd like to display either Sergey or Neo in this example.

should I order the array then use “end” to get the name of the last entry?

Once you change the syntax to PHP, it is one way of doing it.

Use json_decode to convert the json string into a php array.

Loop through the array and create a new array where "5059844" etc are the key and the "level" is the value.

Sort that new array by its value.

Get the first (or last) element in that array

Get the key from that

Use the key you found to select the full info from the original array

echo $original["test_subjects"][ $key ]["name"};

... something roughly along those lines should work.

There's probably a way to do this in only 1 or 2 lines of code but I don't think that way so I can't tell you what it is.
