sql语句为:$sql="select count(*) from com where a_id=$v['id']";

出现以下错误:

( ! ) Parse error: syntax error, unexpected '' (T_ENCAPSED_AND_WHITESPACE), expecting identifier (T_STRING) or variable (T_VARIABLE) or number (T_NUM_STRING) in D:\demo\code\yolo\index\index.php on li

原因:

变量没有用花括号引起来

改为:  $sql="select count(*) from com where a_id={$v['id']}";
