How can I parse json array string to array on php

Question

'[{"a": "1", "b": "2"}, {"a": "3"}]'

seems json_decode allows parse only objects but not arrays. Should it be manually parsed to array before using json_decode?

Seems problem in string. I get a variable with json, and if I output it, looks like the json is valid

echo($jsonvar); //result [{"title":"Home","id":"/","url":"/"}]

but when I try parse string from the variable, the result is nothing even when string is trimmed

echo('[{"title":"Home","id":"/","url":"/"}]', true); //nice parsed array
echo($jsonvar, true); //nothing
echo(trim($jsonvar, " \t\n\r\0\x0B"), true); //nothing

How has this gotten two votes? If the documentation was actually read then this question would of never gotten asked. From the doc: When TRUE, returned objects will be converted into associative arrays. ` — SamV

Believe or not, json_decode() can actually decode JSON; any kind of valid JSON. I can't figure out how you reached a different conclusion. — Álvaro González

The problem has been solved with the following code json_decode(html_entity_decode($jsonvar));, Sorry for the dumb question, it cannot be removed because of answers. I thought the reason was in array. — IgorCh

Pass the true as a second parameter to your json_decode() to parse the json string to array.

$json='[{"a": "1", "b": "2"}, {"a": "3"}]';
$arr= json_decode($json,true); 
print_r($arr);

You can get the json into array by using the true flag in json_decode()

<?php
$str = '[{"a": "1", "b": "2"}, {"a": "3"}]';
$arr=json_decode($str,true);
print_r($arr);
