如何解析json中的字符串？

Question

I have a string like this:

 0: array( 'name' => 'john', 'username' => 'foo' ) 1: array( 'name' => 'jack', 'username' => 'foo' )"

how I can encode it in json? I tried with:

$value = array_values($arr);
var_dump($value);

but I get NULL

UPDATE - If I do json_encode($arr); I get:

 ""
 0: array(
 'name' => 'john',
 'username' => 'foo'
 )
 1: array(
 'name' => 'jack',
 'username' => 'foo'
 )""

Take a look at json_encode php function. I believe this is what you're looking for.

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

echo json_encode($arr);
?>
