This article mainly introduces the PHP parsing HTTP GET JSON string variable is always blank null solution, personal experience of the summary, recommended here to you.

There is a problem with the colleague project today, the JSON string obtained through the HTTP interface is never parsed correctly using Json_decode, which returns white space.

Directly copy the result string to manually create a variable but normal, in the front-end JS can also parse, engaged in a half-day not its solution, with the help of powerful Google solved the problem, the answer is the interface spit out the result contains a BOM head, BOM head this thing is PHP's mortal enemy AH

Do not say, the immediate solution:

The code is as follows:

if (substr ($return, 0,3) = = Pack ("CCC", 0XEF,0XBB,0XBF)) {
$return = substr ($return, 3);
}
$data = Json_decode ($return, true);
