Question

我对编码很新，最近刚开始将功能集成到我的PHP中。我正在尝试对Google Analytics的IP地址进行编码和回显。这就是我的自定义修改器的样子：

pagetracker._setCustomVar(1, "IP", "<?php include function.php; echo remove_numbers_advanced($_SERVER['REMOTE_ADDR']); ?>", 2);

函数文件如下所示：

<?
function remove_numbers_advanced($string)
{
    $numbers = array();
    for($counter =0; $counter <= 10; $counter++) {
        $numbers[$counter] = $counter;


    $replacements = array("A","7","B","6","C","4","D","3","E","F");
    $string = str_replace($numbers, $replacements, $string);
    return $string;
}';

echo remove_numbers_advanced($string);
?>

当我将自定义变量的PHP部分隔离以试图测试它时，页面会抛出500错误，向我建议我的脚本设置有问题。

请记住，我对这个如此简单的术语和例子很新，这对我来说很有帮助！

Answer 1

您的功能中存在少量错误。正确的功能是：

function remove_numbers_advanced($string)
{
    $numbers = array();
    for($counter =0; $counter <= 10; $counter++) 
        $numbers[$counter] = $counter;


    $replacements = array("A","7","B","6","C","4","D","3","E","F");
    $string = str_replace($numbers, $replacements, $string);
    return $string;
}

1-您在for循环旁边添加了开放花括号但未关闭它

2-在功能的闭合括号中还有“';”。它不应该存在。

Answer 2

include函数必须有一个字符串参数，所以把''放在文件名

pagetracker._setCustomVar(1, "IP", "<?php include 'function.php'; echo remove_numbers_advanced($_SERVER['REMOTE_ADDR']); ?>", 2);

PHP函数 - 未知失败
