例如

$pop = array("0"=>"p1","1"=>"p2","2"=>"p3","3"=>"p4","a4"=>"p5","5"=>"p6","6"=>"p7","7"=>"p8","8"=>"p9");

echo json_encode(array('reward_code'=> 4 ,"pop"=>"$pop[a4]" ));

这是正确的

echo json_encode(array('reward_code'=> 4 ,"pop"=>"$pop['a4']" ));

这是错误的，报：

syntax error, unexpected T_ENCAPSED_AND_WHITESPACE, expecting T_STRING or T_VARIABLE or T_NUM_STRING in
