Php 我在脚本中遇到此错误（语法错误意外T_ELSE）

关于paypal IPN，我的脚本有一些问题。 我使用PHPDesigner 7，它在第（88）行给我一个红色错误，我真的试着看看是否有一个大括号丢失了，或者是否有什么地方出错了，但似乎没有什么问题。hoveren PHPDesigner在第88行显示了我的确切位置（语法错误出乎意料）

任何帮助都将受到感谢

这是我的代码：

    <?php

// PHP 4.1

// read the post from PayPal system and add 'cmd'

$req = 'cmd=_notify-validate';

$File = "errorss.txt"; 
 $Handle = fopen($File, 'w');
 $Data = "Entered the IPN script\n"; 
 fwrite($Handle, $Data); 

foreach ($_POST as $key => $value) {
$value = urlencode(stripslashes($value));
$req .= "&$key=$value";
}

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

 $Data = "Authentication Complete\n"; 
 fwrite($Handle, $Data); 

// assign posted variables to local variables
$item_name = $_POST['item_name'];
$item_number = $_POST['item_number'];
$payment_status = $_POST['payment_status'];
$payment_amount = $_POST['mc_gross'];
$payment_currency = $_POST['mc_currency'];
$txn_id = $_POST['txn_id'];
$receiver_email = $_POST['receiver_email'];
$payer_email = $_POST['payer_email'];
$payment_gross = $_POST['payment_gross'];
$payment_fee = $_POST['payment_fee'];

 $Data = "Iten number:".$item_number." ".$payment_status."\n"; 
 fwrite($Handle, $Data); 

if (!$fp) {


 $Data = "Error\n"; 
 fwrite($Handle, $Data); 

} else {
fputs ($fp, $header . $req);
while (!feof($fp)) {
$res = fgets ($fp, 1024);
if (strcmp ($res, "VERIFIED") == 0) {

 $Data = "Verified\n"; 
 fwrite($Handle, $Data); 
    if($payment_status == "Completed")
    {

 $Data = "Completed\n"; 
 fwrite($Handle, $Data); 

require_once('./dbconnect.php');



$kkql= mysql_query("SELECT * FROM orders WHERE w='$item_number'");



                if(mysql_num_rows($kkql) == 0)
                    {

                    exit(); 
                    } 

                                 mysql_query("UPDATE orders SET paid='1'");







                }
    }
}
else if (strcmp ($res, "INVALID") == 0) {
// log for manual investigation
}

}
fclose ($fp);


} //This is also causing the error i think as it is red when it click on it, open and closed braces are displayed in green this one in red
 fclose($Handle); 
?>

拆下第87行的闭合支架
}
（85或86，如果您愿意）

这是假设您想要
else if
而不是第88行的
if
，
else if（strcmp（$res，“INVALID”）==0{
，问题是这个else不适合代码的其余部分

else if (strcmp ($res, "INVALID") == 0) {
    // log for manual investigation
}

我想你的意思可能是这样的

<?php

// read the post from PayPal system and add 'cmd'

$req = 'cmd=_notify-validate';

$File = "errorss.txt"; 
$Handle = fopen($File, 'w');

fwrite($Handle, $Data); 

foreach ($_POST as $key => $value) {
    $value = urlencode(stripslashes($value));
    $req .= "&$key=$value";
}

// post back to PayPal system to validate
$header .= "POST /cgi-bin/webscr HTTP/1.0\r\n";
$header .= "Content-Type: application/x-www-form-urlencoded\r\n";
$header .= "Content-Length: " . strlen($req) . "\r\n\r\n";
$fp = fsockopen ('ssl://www.paypal.com', 443, $errno, $errstr, 30);

$Data = "Authentication Complete\n"; 
fwrite($Handle, $Data); 

// assign posted variables to local variables
$item_name = $_POST['item_name'];

$payer_email = $_POST['payer_email'];
$payment_gross = $_POST['payment_gross'];
$payment_fee = $_POST['payment_fee'];

$Data = "Iten number:".$item_number." ".$payment_status."\n"; 
fwrite($Handle, $Data); 

if (!$fp) {
 $Data = "Error\n"; 
 fwrite($Handle, $Data); 
} else {
    fputs ($fp, $header . $req);
    while (!feof($fp)) {
        $res = fgets ($fp, 1024);
        if (strcmp ($res, "VERIFIED") == 0) {
            $Data = "Verified\n"; 
            fwrite($Handle, $Data); 
            if($payment_status == "Completed")
            {
                $Data = "Completed\n"; 
                fwrite($Handle, $Data); 
                require_once('./dbconnect.php');
                $kkql= mysql_query("SELECT * FROM orders WHERE w='$item_number'");
                if(mysql_num_rows($kkql) == 0)
                {
                    exit(); 
                } 
                mysql_query("UPDATE orders SET paid='1'");
            }
        }
        if (strcmp ($res, "INVALID") == 0) {
            // log for manual investigation
        }
    }
}
    fclose ($fp);
} //This is also causing the error i think as it is red when it click on it, open and closed braces are displayed in green this one in red
fclose($Handle); 
?>

根据我的评论，您有n个额外的
，并且您的
elseif
条件没有父if条件尝试将其放在您的
if
之后，并删除最后一个结束

如果代码缩进一致，则查找不匹配的括号会容易得多。如果
没有任何父级
如果
它位于
else
案例中，则会有一个额外的结尾
如果
没有父级
它位于
else
案例中获取一个支持php的IDE来编辑您的代码它。。。他们会指出你缺少的括号在哪里
