Today, a colleague encountered a problem in his project. The json string obtained through the http interface cannot be parsed correctly using json_decode and returns a blank.
Copy the result string directly and create a variable manually, but it works fine. It can also be parsed in the front-end js. I couldn’t figure it out for a long time. I solved the problem with the help of the powerful Google. The answer is that the result spit out by the interface contains a BOM header. The BOM header can be said to be the mortal enemy of PHP
No more talking, let’s go straight to the 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);
Record it here and share it with everyone. I hope it can be helpful to everyone.
