从以下两个文件我得到输出(2000)1但它应该只(2000)
使用curl获得价值后,附加1会附加,但为什么呢？
balance.PHP
<?PHP $url = "http://localhost/sms/app/user_balance.PHP"; $ch = curl_init(); curl_setopt($ch,CURLOPT_URL,$url); curl_setopt($ch,CURLOPT_POST,2); curl_setopt($ch,CURLOPT_POSTFIELDS,"id=2&status=Y"); $result = curl_exec($ch); curl_close($ch); echo $result; ?>
user_balance.PHP
<?PHP $conn = MysqL_connect("localhost","root",""); MysqL_select_db("sms",$conn); $user_id = $_REQUEST["id"]; $sql = "SELECT * FROM user_sms WHERE user_id='$user_id'"; $rec = MysqL_query($sql); if($row = MysqL_fetch_array($rec)) { $balance = $row["user_sms_balance"]; } echo "(".$balance.")"; ?>
从
curl_setopt()的PHP手册文档：
CURLOPT_RETURNTRANSFER – Set value to TRUE to return the transfer as a string of the return value of curl_exec() instead of outputting it out directly.
如果不设置CURLOPT_RETURNTRANSFER选项设置为TRUE,然后从curl_exec()的返回值将是操作的布尔值 – 1或0.为了避免它,你可以设置CURLOPT_RETURNTRANSFER为TRUE,如下图所示：
curl_setopt($ch,CURLOPT_RETURNTRANSFER,1);
