JSON numeric value altered on php json_decode

When I JSON decoded the JSON in my php one of the numeric value is altered. My JSON is given below:

[
    {
        "__m":"m_0_7p"
    },
   100001572061234,
   null,
   "profile_friends",
   "pb_friends_tl",
   "\/ajax\/add_friend\/action.php",
   "",
   true,
   null,
   false,
   null,
   null,
   "friends_tab",
   []
]

On Json decode the output for the above json is

Array ( [0] => stdClass Object ( [__m] => m_0_7o ) [1] => 1.000091378372E+14 [2] => [3] => profile_friends [4] => pb_friends_tl [5] => /ajax/add_friend/action.php [6] => [7] => 1 [8] => [9] => [10] => [11] => [12] => friends_tab [13] => Array ( ) )

where '100001572061234' changed into 1.000091378372E+14. Don't know why this is happening.

When PHP displays numbers, it uses the php.ini precision setting to decide whether it should display all digits, or use scientific format..... this is a display setting, it doesn't change the value internally.

However, that value is too large for a signed integer in 32-bit PHP, so it will be treated as a float in PHP

From PHP 5.4.0 you have an option to use the option flags to determine how large integer values are to be handled 

$decoded = json_decode($encoded, false, null, JSON_BIGINT_AS_STRING);
